Timer - Delay-on-Make
TDM / TDMH / TDML Series
The TDM Series is a delay-on-make timer that
combines accurate digital circuitry with isolated,
DPDT relay contacts in an industry standard
8-pin plug-in package. DIP switch adjustment
allows precise selection of the time delay over
the full time delay range. The TDM Series is the
product of choice for custom control panel and
OEM designers .
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output relay
energizes and remains energized until input voltage is
removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
HRDM Series
The HRDM Series combines an electromechanical
relay output with microcontroller timing circuitry.
It offers 12 to 230V operation in five ranges and
factory fixed, onboard, or external adjustable
time delays with a repeat accuracy of ±0.5%. The
output contact rating allows for direct operation of
heavy loads, such as compressors, pumps, blower
motors, heaters, etc. This series is ideal for OEM
applications where cost is a factor.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output relay
energizes and remains energized until input voltage is
removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
ERDM Series
Econo-Timers are a combination of digital
electronics and a reliable electromechanical relay.
These devices offer a DPDT relay output for relay
logic circuits, and isolation of input to output
voltages. Cost effective for OEM applications, such
as random starting, sequencing ON, switch debouncing, anti-short cycling, and other common
delay-on-make applications.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
KSDU/ TDU Series
The TDU and KSDU Series are encapsulated solidstate, delay-on-make timers that combine digital
timing circuitry with universal voltage operation.
The TDU offers DIP switch adjustment allowing
accurate selection of the time delay over the full
time delay range. The KSDU is factory fixed from
0.1s to 10,230s and does not include the DIP switch.
These series are excellent choices for process
control systems and OEM equipment .
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

The TSD1 Series is designed for more demanding
commercial and industrial applications where small
size and accurate performance is required. The
factory calibration for fixed time delays is within
1% of the target time delay. The repeat accuracy,
under stable conditions, is 0.1% of the time delay.
The TSD1 Series is rated to operate over an extended
temperature range. Time delays of 0.1 seconds to 100
hours are available. The output is rated 1A steady
and 10A inrush. The modules are totally solid state
and encapsulated to protect the electronic circuitry.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
THD1 Series
The THD1 Series combines accurate timing
circuitry with high power solid-state switching.
It can switch motors, lamps, and heaters directly
without a contactor. You can reduce labor,
component cost, and increase reliability with these
small, easy-to-use, Digi-Power timers.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
KSD1 Series
The KSD1 Series features two-terminal, seriesconnection with the load. The KSD1 Series
is an ideal choice for delay-on-make timing
applications. This series is designed for general
purpose commercial and industrial applications
where a small, cost effective, reliable solid-state
timer is required. The factory calibration for fixed
time delays is within 5% of the target time delay.
The repeat accuracy, under stable conditions,
is 0.5% of the selected time delay. This series is
designed for popular AC and DC voltages. Time
delays of 0.1 seconds to 1000 minutes are available
in 6 ranges. The output is rated 1A steady and 10A
inrush. The modules are totally solid state and
encapsulated to protect the electronic circuitry.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
TH1 Series
The TH1 Series is a solid-state relay and timer
combined into one compact, easy-to-use control.
This highly reliable device eliminates the need
for a separate solid-state relay. When mounted to
a metal surface, it can switch load currents up to
20A steady state, and 200A inrush.
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
MSM Series
The MSM replaces bi-metal type timing with
reliable solid-state circuitry. There are no moving
parts to arc or wear. It is a cost effective solution
for OEM designers. It is available for printed
circuit board mounting or surface mounting with a
removable bracket and wire leads. The MSM offers
immediate reset on removal of power.
Operation (Delay-on-Make):
The time delay begins upon application of input voltage.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Delay-on-Make
TSD4 Series
The TSD4 Digi-Timer is a delay-on-make timer
with a normally closed solid-state output. The load
is energized prior to and during the delay period.
The TSD Series is designed for more demanding
commercial and industrial applications where
small size and accurate performance are required.
The factory calibration for fixed time delays is
within 1% of the target time delay. The repeat
accuracy, under stable conditions, is 0.1% of the
time delay. The TSD Series is rated to operate over
an extended temperature range. Time delays of 0.1
seconds to 100 hours are available. The output is
rated 1A steady and 10A inrush. The modules are
totally solid state and encapsulated to protect the
electronic circuitry .
Operation (Delay-on-Make NC):
Upon application of input voltage, the load energizes
immediately. When the initiate switch is closed, the
time delay begins. At the end of the time delay, the load
de-energizes.
Reset: When the initiate switch is reopened, the load
energizes again and the time delay is reset. Removing
input voltage resets the time delay.

Timer - Delay-on-Make
THD4 Series
The THD4 utilizes solid-state circuitry and a
solid-state relay in one easy to use control. The
metallized mounting surface allows a metal panel
to dissipate heat rather than adding an expensive
heat sink. The solid-state output is rated 6, 10, or 20
amps steady and up to 200 amps inrush. Motors,
heaters and valves can be switched directly,
eliminating the expense of a separate contactor.
The THD4 offers substantial performance,
reliability, and cost advantages for OEM designers.
Operation (Delay-on-Make NC):
Upon application of input voltage, the load is energized
immediately. When the initiate switch closes, the time
delay begins. At the end of the time delay, the load
de-energizes.
Reset: When the initiate switch is reopened, the load is
again energized and the time delay is reset. Removing
input voltage resets the time delay and the output.

Timer - Delay-on-Make
TS4 Series
The TS4 Versa-Timer is an analog delay-on-make
timer with a normally closed solid-state output.
Unlike an interval timer, the load is energized prior
to and during the time delay period. It can be used
as a faster starting interval time delay when S1 is
closed upon application of input voltage.
Operation (Delay-on-Make NC):
Upon application of input voltage, the load is energized
immediately. When the initiate switch is closed, the
time delay begins. At the end of the time delay, the load
de-energizes.
Reset: When the initiate switch is reopened, the load again
energizes and the time delay is reset. Removing input
voltage resets the time delay and output.

Timer - Delay-on-Break
TDB / TDBH / TDBL Series
The TDB Series combines accurate digital circuitry
with isolated, 10A, DPDT or SPDT contacts in an 8
or 11-pin plug-in package. The TDB Series features
DIP switch selectable time delays ranging from
0.1-10,230 seconds in three ranges. The TDB Series
is the product of choice for custom control panel
and OEM designers .
Operation (Delay-on-Break):
Input voltage must be applied to the input before and
during timing. Upon closure of the initiate switch, the
output relay is energized. The time delay begins when
the initiate switch is opened (trailing edge triggered).
The output remains energized during timing. At the
end of the time delay, the output de-energizes. The
output will energize if the initiate switch is closed when
input voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time delay
and output .

Timer - Delay-on-Break
TRB Series
Features:
The TRB Series combines an isolated, 10A
electromechanical relay output with analog timing
circuitry. False trigger of the TRB by a transient is
unlikely because of the complete isolation of the
circuit from the line prior to initiation. The initiate
contact is common to one side of the line and may
be utilized to operate other loads. Installation is
easy due to the TRB’s industry standard 8 or 11-pin
plug-in base wiring.
Connection:
8-pin octal SPDT
• Onboard adjustable time delays
• Fixed or adjustable delays from 0.05 - 600s in

Timer - Delay-on-Break
The PRLB Series is designed for use on non-critical
timing applications. It offers low cost, knob
adjustable timing control, full 10A relay output,
and onboard LED indication. The knob adjustment
provides a guaranteed time range of up to 10
minutes in 6 ranges. The onboard LED indicates
whether or not the unit is timing (flashing LED)
as well as the status of the output.
Operation (Delay-on-Break):
Input voltage must be applied at all times prior to and
during timing. Upon closure of the initiate switch, the
output contacts transfer and remain transferred if no
further action is taken. The LED is on steady. When the
initiate switch is opened, the time delay is started. The
LED flashes during timing. At the conclusion of the delay,
the output contacts revert to their original unenergized
position. Applying input voltage with the initiate switch
closed will energize the load.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time delay
and output .

Timer - Delay-on-Break
HRDB Series
The HRDB Series combines an electromechanical,
relay output with microcontroller timing circuitry.
The HRDB offers 12 to 230V operation in five
options and factory fixed, external, or onboard
adjustable time delays with a repeat accuracy of
±0.5%. The isolated output contact rating allows
for direct operation of heavy loads, such as
compressors, pumps, blower motors, heaters, etc.
The HRDB is ideal for OEM applications where
cost is a factor.
Operation (Delay-on-Break):
Input voltage must be applied before and during timing.
Upon closure of the initiate switch, the output relay
energizes. The time delay begins when the initiate switch
is opened. The output remains energized during timing.
At the end of the time delay, the output de-energizes. The
output will energize if the initiate switch is closed when
input voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time delay
and output .

with universal voltage operation. Voltages of
24 to 240VAC and 12 to 24VDC are available in
three ranges. The TDUB Series offers DIP switch
selectable time delays ranging from 0.1 seconds to
102.3 minutes in three ranges. Its 1A rated output,
ability to operate on multiple voltages, and wide
range of switch selectable time delays make the
TDUB Series an excellent choice for process control
systems and OEM equipment .
Features:
Operation (Delay-on-Break):
Input voltage must be applied before and during timing.
Upon closure of the initiate switch, the output energizes.
The time delay begins when the initiate switch is opened
(trailing edge triggered). The output remains energized
during timing. At the end of the time delay, the output
de-energizes. The output will energize if the initiate switch
is closed when input voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the time delay
and output .

Timer - Interval/Delay-on-Break
TSD7 Series
The TSD7 utilizes only two terminals connected in
series with the load. Interval timing mode period
is achieved by using a small portion of the AC
sine wave allowing sufficient voltage for circuit
operation. It can be used as an interval timer to
control or pulse shape the operation of contactors,
solenoids, relays, and lamp loads. The TSD7 can be
wired to delay on the break of a switch for energy
saving fan delays.
Connection:

Interval
Operation (Interval):
Upon application of input voltage, the output energizes
and the time delay begins. The output remains energized
throughout the time delay. At the end of the time delay,
the output de-energizes and remains de-energized until
power is removed.
Reset: Removing input voltage resets the time delay and
the output.
Operation (Delay-on-Break):
Upon closure of SW1, the load is energized and the timer is
reset (zero volts across its input terminals). Opening SW1
re-applies input voltage to the timer, the load remains
energized and the time delay begins. At the end of the
time delay, the output de-energizes. If SW1 is open when
power is applied, the load will energize for the time delay
then de-energize.
Reset: Reclosing SW1 resets the timer.

Timer - Delay-on-Break
TSB Series
The TSB Series is a totally solid-state, delay-onbreak timing module. The TSB is available with a
fixed, external, or onboard adjustable time delay.
Time Delays from 0.05 to 600 seconds, in 4 standard
ranges, cover over 90% of all OEM and commercial
appliance timing applications. The repeat accuracy
is ±2%. Operating voltages of 24, 120, or 230VAC
are available. The TSB’s 1A steady state, 10A rated,
solid-state output is perfect for direct control of
solenoids, contactors, relays, lamps, buzzers, and
small heaters. The TSB can be surface mounted
with a single screw, or snapped on a 35 mm DIN
rail using the P1023-20 adaptor.
Operation (Delay-on-Break):
Input voltage must be applied before and during timing.
Upon closure of the initiate switch, the output energizes.
The time delay begins when the initiate switch opens.
The output remains energized during timing. At the end
of the time delay, the output de-energizes. The output
will energize if the initiate switch is closed when input
voltage is applied.
Reset: Reclosing the initiate switch during timing resets
the time delay. Loss of input voltage resets the output
and the time delay.

Timer - Single Shot
TDS / TDSH / TDSL Series
Features:
The TDS Series combines accurate digital circuitry
with isolated, 10A rated, DPDT or SPDT relay
contacts in an 8 or 11-pin plug-in package. The
TDS Series features DIP switch selectable time
delays ranging from 0.1s to 10,230s in three ranges.
The TDS Series is the product of choice for custom
control panel and OEM designers .
• Switch selectable time delay
• Three time ranges from 0.1s - 10,230s
• ±0.1% repeat accuracy
• ±2% setting accuracy
• 10A, SPDT or DPDT output contacts
• LED indication
Approvals:
Operation (Single Shot):
Input voltage must be applied to the input before and
during timing . Upon momentary or maintained closure
of the initiate switch (leading edge triggered), the output
relay energizes for a measured interval of time. At the
end of the delay, the output de-energizes. Opening or
reclosing the initiate switch during timing has no affect
on the time delay. The output will energize if the initiate
switch is closed when input voltage is applied.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets
the time delay and output.

Timer - Single Shot
TRS Series
The TRS Series combines an isolated, 10A
electromechanical, relay output with analog timing
circuitry. False trigger of the TRS by a transient is
unlikely because of the complete isolation of the
circuit from the line prior to initiation. The initiate
contact is common to one side of the line and may
be utilized to operate other loads. Installation is
easy due to the TRS’s industry standard 8 or 11-pin
plug-in base wiring.
Operation (Single Shot):
Input voltage must be applied to the input before and
during timing . Upon momentary or maintained closure
of the initiate switch (leading edge triggered), the output
energizes for a measured interval of time. At the end of
the delay, the output de-energizes. Opening or reclosing
the initiate switch during timing has no affect on the time
delay. Applying input voltage with the initiate switch
closed will energize the load and begin the time delay.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets
the time delay and output.

Timer - Single Shot
PRLS Series
The PRLS Series is designed for use on non-critical
timing applications. It offers low cost, knob
adjustable timing control; full 10A relay output;
and onboard LED indication. The knob adjustment
provides a guaranteed time range of up to 10
minutes in 6 ranges. The onboard LED indicates
whether or not the unit is timing (flashing LED)
as well as the status of the output.
Operation (Single Shot):
Input voltage must be applied to the input at all times
prior to and during timing. Upon closure of the initiate
switch (momentary or maintained) the output contacts
transfer and the time delay is initiated. The LED flashes
during timing. At the end of the delay, the output contacts
revert to their original position. If the initiate switch is
reclosed during timing, the time delay will not be affected.
Applying input voltage with the intiate switch closed will
energize the load and begin the time delay.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets
the time delay and output.

Timer - Single Shot
HRDS Series
The HRDS Series combines an electromechanical
relay output with microcontroller timing circuitry.
It offers 12 to 230V operation in five options and
factory fixed, onboard or external adjustable
time delays with a repeat accuracy of ±0.5%. The
output contact rating allows for direct operation of
heavy loads, such as compressors, pumps, blower
motors, heaters, etc. This series is ideal for OEM
applications where cost is a factor.
Operation (Single Shot):
Input voltage must be applied before and during timing.
Upon momentary or maintained closure of the initiate
switch, the output relay energizes for a measured interval
of time. At the end of the delay, the output de-energizes.
Opening or reclosing the initiate switch during timing has
no affect on the time delay. The output will energize if the
initiate switch is closed when input voltage is applied.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets
the time delay and output.

Timer - Interval/Single Shot
ERDI Series
Econo-Timers are a combination of digital
electronics and an electromechanical relay. DPDT
relay output for relay logic circuits, and isolation
of input to output voltages. For applications, such
as interval on, pulse shaping, minimum run time,
etc. The ERD Series is encapsulated to protect the
circuitry from shock, vibration and humidity.

Interval
Operation (Interval):
Upon application of input voltage, time delay begins, and
output relay energizes. At the end of time delay, output
de-energizes until input voltage is removed.
Reset: Removing input voltage resets the time delay and
the output.
Operation (Single Shot):
Input voltage must be applied before & during timing.
Upon momentary or maintained closure of initiate switch,
output relay energizes for time delay. At the end of the
delay, output de-energizes. Opening or reclosing initiate
switch during timing has no affect on time delay. Output
will energize if initiate switch is closed when input voltage
is applied .
Reset: Reset occurs when time delay is complete & initiate
switch is opened. Loss of input voltage resets time delay
& output.

Timer - Single Shot
KRDS Series
Features:
The KRDS Series is a compact time delay relay
measuring only 2 in. (50.8 mm) square. Its
microcontroller timing circuit provides excellent
repeat accuracy and stability . Encapsulation
protects against shock, vibration, and humidity.
The KRDS Series is a cost effective approach for
OEM applications that require small size, isolation,
reliability, and long life.
Operation (Single Shot):
Input voltage must be applied before and during timing.
Upon momentary or maintained closure of the initiate
switch, the output relay energizes for a measured interval
of time. At the end of the delay, the output de-energizes.
Opening or reclosing the initiate switch during timing has
no affect on the time delay. The output will energize if the
initiate switch is closed when input voltage is applied.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets
the time delay and output.

Timer - Single Shot
TSDS Series
The TSD Series is designed for more demanding
commercial and industrial applications where
small size and accurate performance are required.
The factory calibration for fixed time delays is
within 1% of the target time delay. The repeat
accuracy, under stable conditions, is 0.5% of the
time delay. The TSD Series is rated to operate over
an extended temperature range. Time delays of 0.1
seconds to 1000 minutes are available. The output
is rated 1A steady and 10A inrush. The modules
are totally solid state and encapsulated to protect
the electronic circuitry. This product is suitable for
many applications, including dispensing, welding,
and exposure timing.

Operation (Single Shot):
Input voltage must be applied before and during timing.
Upon momentary or maintained closure of the initiate
switch, the output energizes for a measured interval of
time. At the end of the delay, the output de-energizes.
Opening or reclosing the initiate switch during timing has
no affect on the time delay. The output will not energize if
the initiate switch is closed when input voltage is applied.
Reset: Reset occurs when the time delay is complete and
the initiate switch is opened. Loss of input voltage resets
the time delay and output.

Upon momentary or maintained closure of the initiate
switch, the output energizes for a measured interval of
time. At the end of the delay, the output de-energizes.
Opening or reclosing the initiate switch during timing
has no affect on the time delay. The output energizes if

The KSDS Series is ideal for applications that
require momentary start interval timing including
dispensing, exposure timing, or pulse shaping.
This series is available for both AC and DC
voltages. This series is designed for general
purpose commercial and industrial applications
where a small, cost effective, reliable solid-state
timer is required. The factory calibration for fixed
time delays is within 5% of the target time delay.
The repeat accuracy, under stable conditions, is
0.5% of the selected time delay. Time delays of 0.1
seconds to 1000 minutes are available in 6 ranges.
The output is rated 1A steady and 10A inrush. The
modules are totally solid state and encapsulated
to protect the electronic circuitry.

Timer - Single Shot
TSS Series
The TSS is a totally solid-state timing module. Its
1A rated, solid-state output provides an excellent
method of time control for exposures, dispensing,
or for increasing or decreasing a switch closure.
Time delays from 0.05 to 600 seconds, in 4 ranges,
cover 90% of all OEM applications. Factory
calibration of fixed delays is ±5% and the repeat
accuracy is ±2%. The TSS can be surface mounted
with a single screw, or snapped on a 35mm DIN
rail using the P1023-20 accessory adaptor.
Operation (Single Shot):
Voltage must be applied before and during timing. Upon
momentary or maintained closure of the initiate switch,
the output energizes for a measured interval of time. At
the end of the delay, the output de-energizes. Opening or
reclosing the initiate switch during timing has no affect
on the time delay. The output will energize if the initiate
switch is closed when input voltage is applied.
Reset: Reset occurs when the time delay is complete and
the initiate switch opens. Loss of input voltage resets the
time delay and output .

Timer - Single Shot
THC / THS Series
The TH series is a solid-state relay and timer
combined into one compact, easy-to-use control.
When mounted to a metal surface, the TH Series
may be used to directly control lamp or heater
loads of up to 20A steady, 200A inrush. Its single
shot function can perform dispensing and pulse
shaping operations. The initiate switch can be a
momentary or maintained type of switch. Time
delays can be selected from 0.1 - 600 seconds
in 4 ranges. The THC Series is used for coin
vending applications where fast initiate response
is required .
Operation (Single Shot):
Input voltage must be applied before and during timing.
Upon momentary or maintained closure of the initiate
switch (leading edge triggered), the output energizes for
a measured interval of time. At the end of the delay, the
output de-energizes. Opening or reclosing the initiate
switch during timing has no affect on the time delay. The
output will energize if the initiate switch is closed when
input voltage is applied.
Reset: Reset occurs when the time delay is complete and
the initiate switch opens. Loss of input voltage resets the
time delay and output .

Timer - Retriggerable Single Shot
HRD9 Series
The HRD9 Series combines an electromechanical
relay output with microcontroller timing circuitry.
It offers 12 to 230V operation in five ranges and
factory fixed, external, or onboard adjustable
time delays with a repeat accuracy of ±0.5%. The
isolated output contact rating allows for direct
operation of heavy loads, such as compressors,
pumps, blower motors, heaters, etc. The HRD9 is
ideal for OEM applications where cost is a factor.
Operation (Motion Detector/Retriggerable Single Shot):
Input voltage must be applied prior to and during timing.
The output is de-energized. Upon closure of the initiate
switch (momentary or maintained) the output energizes
and the time delay starts. On completion of the delay
period, the output de-energizes.
Reset: Reclosing the initiate switch during or after timing
will reset the time delay and restart timing. Reset is also
accomplished by removing and reapplying input voltage.
Note: Powering up the unit with the initiate switch closed
will not energize the output relay or start timing.

Timer - Retriggerable Single Shot
KRD9 Series
Features:
The KRD9 Series microcontroller timing circuit
provides excellent repeat accuracy and stability.
Cost effective approach for OEM applications
that require small size, isolation, reliability, and
long life.
Operation (Retriggerable Single Shot):
Function Type A (Output Initially De-energized): Input
voltage must be applied prior to and during timing. When
the initiate switch is closed, (momentary or maintained)
the output energizes and the time delay starts. On
completion of the delay, the output de-energizes. The unit
will time out if S1 remains in the open or closed position
for the full time delay. Reclosing the initiate switch resets
the time delay and restarts timing; the output remains
energized. The output will not energize if the initiate
switch is closed when input voltage is applied.
Function Type B (Output Initially Energized): Upon
application of input voltage, the output energizes and the
time delay starts. At the end of the time delay, the load
de-energizes. The unit will time out if S1 remains in the
open or closed position for the full time delay. Closing
(re-closing) the initiate switch resets the time delay and
restarts timing; the output remains energized.
Reset: The time delay and the output are reset when input
voltage is removed.

HRDI Series
The HRDI Series combines an electromechanical
relay output with microcontroller timing circuitry.
It offers 12 to 230V operation in five ranges and
factory fixed, external, or onboard adjustable
time delays with a repeat accuracy of ±0.5%. The
output contact rating allows for direct operation of
heavy loads, such as compressors, pumps, blower
motors, heaters, etc. This series is ideal for OEM
applications where cost is a factor.
Operation (Interval):
Upon application of input voltage, the time delay begins.
The output relay is energized during the time delay. At
the end of the time delay, the output de-energizes and
remains de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and the output.

The KRDI Series is a compact time-delay relay
measuring only 2 in. (50.8 mm) square. Its solidstate timing circuit provides excellent repeat
accuracy and stability . Encapsulation protects
against shock, vibration, and humidity. The
KRDI Series is a cost effective approach for OEM
applications that require small size, isolation,
reliability, and long life.
Operation (Interval):
Upon application of input voltage, the time delay begins.
The output relay energizes during the time delay. At
the end of the time delay, the output de-energizes and
remains de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and
the output.

TSD2 Series
The TSD Series is designed for more demanding
commercial and industrial applications where
small size and accurate performance are required.
The factory calibration for fixed time delays is
within 1% of the target time delay. The repeat
accuracy, under stable conditions, is 0.1% of the
time delay. The TSD Series is rated to operate over
an extended temperature range. Time delays of 0.1
seconds to 100 hours are available. The output is
rated 1A steady and 10A inrush. The modules are
totally solid state and encapsulated to protect the
electronic circuitry .
Features:
Operation (Interval):
Upon application of input voltage, the time delay begins.
The output is energized during the time delay. At the end
of the time delay, the output de-energizes and remains
de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and
the output.

TS2 / TS6 Series
The TS2 Series is designed for 24, 120 or 230VAC
and the TS6 Series is designed for 12 or 24VDC.
These series are capable of controlling load
currents of up to 1A steady state, 10A inrush.
Encapsulated circuitry and the reliability of a ±2%
repeat accuracy make the TS2 and TS6 ideal for
cost sensitive applications.
Operation (Interval):
Upon application of input voltage, the time delay begins.
The output energizes during the time delay. At the end
of the time delay, the output de-energizes and remains
de-energized until input voltage is removed.
Reset: Removing input voltage resets the time delay and
the output.

Timer - Recycling
TDR Series
The TDR Series of time-delay relays are comprised
of digital circuitry and an isolated, 10A relay
output. The on and off delays are selected by
means of two, ten position binary switches, which
allow the setting of the desired delay to be precise
every time.
Operation (Recycling - ON Time First):
Upon application of input voltage, the green LED glows,
the output relay is energized, the red LED glows, and
the T1 ON time begins. At the end of the ON time, the
output de-energizes, the red LED turns OFF and the T2,
OFF time begins. At the end of the OFF time, the output
relay energizes and the cycle repeats as long as input
voltage is applied.
Reset: Removing input voltage resets the output and
time delays, and returns the sequence to the first delay.
Operation (Recycling - OFF Time First):
Upon application of input voltage, the green LED glows,
the T1 OFF time begins, the load is OFF. At the end of
the OFF time, the T2 ON time begins, the load energizes,
and the red LED glows. At the end of the ON time the
load de-energizes and the red LED turns OFF. The cycle
repeats until input voltage is removed.
Reset: Removing input voltage resets the output and the
sequence to the OFF time.

Timer - Recycling
HRDR Series
The HRDR Series combines an electromechanical
relay and microcontroller timing circuitry. It offers
12 to 230V operation in five ranges and factory
fixed, onboard or externally adjustable time
delays with a repeat accuracy of ±0.5%. The high
switching capacity of the output contacts allow
for direct control of heavy loads like compressors,
pumps, motors, heaters and lighting. A bypass/
reset switch option allows operator to interrupt
normal recycling sequence and energize output
relay. An excellent choice for OEM applications.
Connection:
L1
N/L2
Operation (Recycling with Reset Switch):
Upon application of input voltage, the ON time T1 begins
and output relay energizes. At the end of the ON time,
the output relay de-energizes and the OFF time T2 begins.
At the end of the OFF time, the output relay energizes
and the cycle repeats as long as input voltage is applied.
Some recycling timers have the OFF time as the first delay.
Reset: Removing input voltage resets output and time
delays, and returns sequence to the first delay.
Bypass/Reset Switch: Closing the normally open bypass/
reset switch energizes the output relay and resets the time
delays. Opening the switch restarts recycling operation
with the first delay.

Timer - Recycling
HRD3 Series
The HRD3 Series combines an electromechanical
relay output with microcontroller timing circuitry.
It offers 12 to 230V operation in five options and
factory fixed, external, or onboard adjustable
time delays with a repeat accuracy of ±0.5%. The
output contact rating allows for direct operation of
heavy loads, such as compressors, pumps, blower
motors, heaters, etc. This series is ideal for OEM
applications where cost is a factor.
Operation (Recycling - ON Time First):
Upon application of input voltage, the output relay
energizes and the T1 ON time begins. At the end of the ON
time, the output de-energizes and the T2 OFF time begins.
At the end of the OFF time, the output relay energizes
and the cycle repeats as long as input voltage is applied
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to the first delay.
Operation (Recycling - OFF Time First):
Upon application of input voltage, the T2, OFF time
begins. At the end of the OFF time, the T1, ON time
begins and the load energizes. At the end of the ON time
the load de-energizes, and the cycle repeats until input
voltage is removed.
Reset: Removing input voltage resets the output and the
sequence to the OFF time.

KRD3 Series
Features
The KRD3 Series measures only 2 in. (50.8
mm) square. Its solid-state timing circuit
provides excellent repeat accuracy and stability.
Encapsulation protects against shock, vibration,
and humidity. The KRD3 Series is a cost effective
approach for OEM applications that require small
size, isolation, reliability, and long life.
Operation (Recycling Flasher - ON Time First):
Upon application of input voltage, the output energizes
and the T1 ON time begins. At the end of the ON time,
the output de-energizes and the T2 OFF time begins. At
the end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to T1 ON time.
Operation (Recycling Flasher - OFF Time First):
Upon application of input voltage, the T2 OFF time begins.
At the end of the OFF time, the T1 ON time begins and
the load energizes. At the end of T1, T2 begins and the
load de-energizes. This cycle repeats until input voltage
is removed.
Reset: Removing input voltage resets the output and the
sequence to T2 OFF time .

Timer - Recycling
RS Series
The RS Series is a solid-state, encapsulated,
recycling timer designed for tough industrial
environments. It is used by many testing labs as
a life cycle tester; by others as a cycle controller.
The RS Series has separate DIP switch adjustments
for the on delay and the off delay. These make
accurate adjustment possible the first time, every
time. Time delays of 0.1 seconds to 1023 hours are
available in 4 ranges.
Operation (Recycling - ON Time First)
Upon application of input voltage, the output energizes
and the T1 ON time begins. At the end of the ON time, the
output de-energizes and the T2 OFF time begins. At the
end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to the ON time.
Operation (Recycling - OFF Time First)
Upon application of input voltage, the T2 OFF time
begins. At the end of the OFF time, the output energizes
and the T1 ON time begins. At the end of the ON time,
the output de-energizes and the cycle repeats as long as
input voltage is applied.
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to the OFF time.

TSDR Series
The TSDR Digi-Timer is an on/off or
off/on recycling timing module designed to
control metering pumps, chemical valves, flash
lamps, or use in energy saving or duty cycling
applications. It may be ordered with both time
delays factory fixed, or one delay fixed and the
other delay external or onboard adjustable. The
TSD Series is designed for more demanding
commercial and industrial applications where
small size and accurate performance are required.
The factory calibration for fixed time delays is
< ±5%. The repeat accuracy, under stable
conditions, is 0.5% of the time delay. The TSD
Series is rated to operate over an extended
temperature range. Time delays of 0.1 seconds to
1000 minutes are available. The output is rated
1A steady and 10A inrush. The modules are
totally solid state and encapsulated to protect the
electronic circuitry .
N/L2
RT is used when external adjustment is ordered.
An onboard adjustment, or terminals 4 & 5 are
only included on adjustable units.
Operation (Recycling - ON Time First):
Upon application of input voltage, the output energizes
and the T1, ON time begins. At the end of the ON time,
the output de-energizes and the T2, OFF time begins. At
the end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and
time delays, and returns the sequence to the T1 ON time.
Operation (Recycling - OFF Time First):
Upon application of input voltage, the T2 OFF time
begins. At the end of the OFF time, the T1 ON time begins
and the load energizes. At the end of the T1, T2 begins
and the load de-energizes. This cycle repeats until input
voltage is removed.
Reset: Removing input voltage resets the output and the
sequence to T2 OFF time .

Timer - Recycling
KSDR Series
The KSDR Series offers independent time
adjustment of both delay periods. The KSDR is
recommended for air drying, automatic oiling,
life testing, chemical metering, and automatic
duty cycling. This series is designed for general
purpose commercial and industrial applications
where a small, cost effective, reliable, solid-state
timer is required. The factory calibration for fixed
time delays is within ± 5% of the target delay. The
repeat accuracy, under stable conditions, is 0.5% of
the selected time delay. This series is designed for
input voltages of 24, 120 or 230VAC. Time delays
of 0.1 seconds to 1000 minutes are available in 6
ranges. The output is rated 1A steady and 10A
inrush. The modules are totally solid state and
encapsulated to protect the electronic circuitry.
Operation (Recycling - ON Time First)
Upon application of input voltage, the output energizes
and the T1, ON time begins. At the end of the ON time,
the output de-energizes and the T2, OFF time begins. At
the end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to T1 ON time.
Operation (Recycling - OFF Time First)
Upon application of input voltage, the T2 OFF time begins.
At the end of the OFF time, the T1 ON time begins and
the load energizes. At the end of T1, T2 begins and the
load de-energizes. This cycle repeats until input voltage
is removed.
Reset: Removing input voltage resets the output and the
sequence to T2 OFF time .

Timer - Recycling Flasher
THD3 Series
The THD Series combines accurate timing circuitry
with high power, solid-state switching. It can
switch motors, lamps, and heaters directly without
a contactor. The THD3 has equal on and off time
delays . A single RT sets both time delays. You
can reduce labor, component cost, and increase
reliability with these small, easy-to-use, DigiPower timers .
Operation (Recycling Flasher - ON Time First):
Upon application of input voltage, the output energizes
and the T1 ON time begins. At the end of the ON time, the
output de-energizes and the T2 OFF time begins. At the
end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to T1 ON time.
Operation (Recycling Flasher - OFF Time First):
Upon application of input voltage, the T2 OFF time begins.
At the end of the OFF time, the T1 ON time begins and
the load energizes. At the end of T1, T2 begins and the
load de-energizes. This cycle repeats until input voltage
is removed.
Reset: Removing input voltage resets the output and the
sequence to T2 OFF time .

Timer - Recycling Flasher
TSD3 Series
The TSD3 is a solid-state ON/OFF recycling
timer with the on time always equal to the off
time. When time delay is changed by the RT,
both the ON and the OFF periods are changed.
The TSD Series is designed for more demanding
commercial and industrial applications where
small size, and accurate performance is required.
The factory calibration for fixed time delays is
within 1% of the target time delay. The repeat
accuracy, under stable conditions, is 0.1% of the
time delay. The TSD Series is rated to operate over
an extended temperature range. Time delays of 0.1
seconds to 100 hours are available. The output is
rated 1A steady and 10A inrush. The modules are
totally solid state and encapsulated to protect the
electronic circuitry .
Operation (Recycling Falsher - ON Time First):
Upon application of input voltage, the output energizes
and the T1, ON time begins. At the end of the ON time,
the output de-energizes and the T2 OFF time begins. At
the end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and
time delays, and returns the sequence to the T1 ON time.

Timer - Recycling Flasher
KSD3 Series
The KSD3 Digi-Timer is a cost effective approach
for ON/OFF recycling applications. The on time
is equal to the off time. An adjustment of the RT
will change the time delays of both on and off
times. This series is designed for general purpose
commercial and industrial applications where a
small, cost effective, reliable, solid-state timer is
required. The factory calibration for fixed time
delays is within 5% of the target time delay. The
repeat accuracy, under stable conditions, is 0.5% of
the selected time delay. This series is designed for
popular AC and DC voltages. Time delays of 0.1
seconds to 1000 minutes are available in 6 ranges.
The output is rated 1A steady and 10A inrush. The
modules are totally solid state and encapsulated
to protect the electronic circuitry.
Operation (Recycling Flasher - ON Time First):
Upon application of input voltage, the output energizes
and the T1, ON time begins. At the end of the ON time,
the output de-energizes and the T2 OFF time begins. At
the end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied.
Reset: Removing input voltage resets the output and time
delays, and returns the sequence to the ON time.
Operation (Recycling Flasher - OFF Time First):
Upon application of input voltage, the T2 OFF time
begins. At the end of the OFF time, the T1 ON time
begins and the load energizes. At the end of the ON time
the load de-energizes, and the cycle repeats until input
voltage is removed.
Reset: Removing input voltage resets the output and time
delays and the sequence to the OFF time.

Timer - Percentage
PTHF Series
The PTHF Series can be used for a variety
of applications from chemical metering, to
temperature regulating, to energy management.
The infinite adjustability from 1 to 99% provides
accurate percentage on control over a wide
factory fixed cycle period. When mounted on a
metal surface, it can be used to drive solenoids,
contactors, relays, or lamps, up to 20A steady,
200A inrush. PTHF is the suggested replacement
for the PT Series.
Operation (Percentage):
Upon application of input voltage, the output energizes
and the T1 ON time begins. At the end of the ON time,
the output de-energizes and the T2 OFF time begins. At
the end of the OFF time, the output energizes and the cycle
repeats as long as input voltage is applied. Increasing the
ON time decreases the OFF time. The total cycle period is
equal to the ON time plus the OFF time. The total cycle
period is factory fixed. ON time range is 1 to 99 percent
of cycle period.
Reset: Removing input voltage resets the output and
time delays, and returns the sequence to the T1 ON time.

Timer - Sequencing
SQ Series
The SQ Series is available with either three (SQ3) or
four (SQ4) outputs and an adjustable or fixed time
delay. The time delay period is the same for each
output. This makes the SQ ideal for applications
like dust collection, automatic lubrication, air
drying, lighting displays, merchandising displays,
duty cycling, and energy management.
Operation (Sequencing):
Upon application of input voltage, Load 1 energizes for
the selected ON time delay. At the end of this ON time
delay, Load 1 de-energizes and Load 2 immediately
energizes starting another ON time delay. At the end
of this ON time delay, Load 2 de-energizes and Load 3
immediately energizes. At the end of the ON time delay
for Load 3 (Load 4 for 4 output devices), Load 1 reenergizes and the cycle repeats. The sequential operation
continues as long as input voltage is applied.
Reset: Removing and re-applying input voltage resets the
sequence to the Load 1 ON time delay.

Timer - Delay-on-Make/Delay-on-Break
The TDMB combines both delay-on-make and
delay-on-break functions into one plug-in package.
Selection of the time period is accomplished with
dual switches, one for the on delay and the other
for the off delay. SPDT or DPDT output options
provide isolated, 10A switching capability.
Operation (Delay-on-Make/Delay-on-Break):
Input voltage must be applied at all times. The output
relay is de-energized. Upon closure of the initiate switch,
the green LED glows and the delay-on-make time delay
(T1) begins. At the end of T1, the output relay energizes
and the red LED glows. When the initiate switch opens,
the green LED turns OFF and the delay-on-break time
delay (T2) begins. At the end of T2, the output relay deenergizes and the red LED turns OFF.
Reset: Removing input voltage resets time delay and
output. Opening the initiate switch during the delay-onmake delay, resets T1. Closing the initiate switch during
the delay-on-break delay, resets T2.

Timer - Delayed Interval
ESD5 Series
The ESD5 Series is an accurate, solid-state, delayed
interval timer. It offers a 1A steady, 10A inrush
output and is available with adjustable or fixed
time delays of 0.1 seconds to 1000 minutes in six
ranges. Input voltages of 24, 120, or 230VAC are
available. Encapsulation offers protection against
shock and vibration. Adjustment options are
factory fixed, onboard or externally adjustable. The
repeat accuracy, under stable conditions, is 0.1%.
The factory calibration of the time delay is ± 5%.
Operation (Delayed Interval):
Upon application of input voltage, the T1 delay-on-make
time delay begins and the output remains de-energized.
At the end of this delay, the output energizes and the T2
interval delay begins. At the end of the interval delay
period, the output de-energizes.
Reset: Removing input voltage resets the output and the
time delays, and returns the sequence to the first delay.

Timer - Delay-on-Make
TAC1 Series
The TAC1 Series was designed to delay the
operation of a compressor relay. It eliminates the
possibility of relay chatter due to half-wave failure
of the output. It connects in series with the load
relay coil and provides a delay-on-make time delay
each time input voltage is applied. It can be used
for random start, anti-short cycling, sequencing,
and many other applications. It is an excellent
choice for all air conditioning and refrigeration
equipment .
Operation (Delay-on-Make):
Upon application of input voltage, the time delay begins.
The output is de-energized before and during the time
delay. At the end of the time delay, the output energizes
and remains energized until input voltage is removed.
Reset: Removing input voltage resets the time delay
and output .

Timer - Lockout
T2D Series
The T2D Series provides protection against short
cycling of compressors and other motors. At the
end of each operation, a lockout delay prevents
restarting the compressor or motor until the delay
is completed. 24VAC models can be used with
thermostats that include a cooling anticipator
resistor. It can be connected in series with the load
for delay-on-make operation.
Operation (Lockout with Random Start):
Connection #1: Upon application of input voltage, a
random start time delay begins. At the end of this time
delay, the output is energized. Lockout Delay: Input
voltage must be applied prior to and during timing.
When the thermostat or initiate switch opens, the output
de-energizes and the lockout time delay begins. At the
end of the lockout delay, the output is energized allowing
the load to immediately energize when the initiate switch
or thermostat closes.
Connection #2: Upon application of input voltage and
closure of initiate switch, the time delay begins. At the
end of the time delay, the output is energized and remains
energized until power is removed.
Reset: Removing power resets the output and the time
delay .

Timer - Bypass
TAC4 Series
The TAC4 is a bypass timer that provides a closure
across the low-pressure switch during compressor
startup. Its time-delay circuit is totally solid
state including the normally closed output. The
molded housing with encapsulation, the single
hole mounting, and 0.25 in. (6.35 mm) termination
makes the TAC4 easy to use, rugged, and reliable.
Operation (Bypass Timer):
(As shown in the connection & function diagrams) Upon
application of input voltage and closure of controller
contact, CC, the load, CR, energizes and the time delay
begins. During the time delay, the TAC4’s solid-state
output bypasses the LPC, low pressure cutout switch.
This allows the compressor controlled by CR to start and
establish acceptable pressure. At the end of the time delay,
TAC4’s output de-energizes and remains de-energized
until reset. The TAC4 may be used in other applications
where a controlling contact must be bypassed for a
specified period of time.
Reset: Removing input voltage or opening CC resets the
output and time delay .

Timer - Lockout
TA Series
The TA Series prevents rapid recycling of a
compressor. A lockout delay is started when
the thermostat opens, or input voltage is lost.
Eliminates tripped circuit breakers or blown fuses
caused by a locked rotor during short cycling. The
TA will not allow the compressor to start when
the line voltage is low. Chatter of the compressor
relay is eliminated. Because of the fast initiate time,
bounce of the thermostat will not be transmitted
to the compressor relay coil. A 30 second delay
provides anti-reversing protection for scroll
compressors .
Operation (Lockout):
On initial closure of the S1, the compressor relay
energizes immediately. When S1 opens or input voltage
is interrupted, a lockout time delay is initiated. During
this lockout time delay, the compressor relay cannot
be energized. The low voltage (brownout) protection
prevents energization of the compressor when the line
voltage is low.
Reset: The lockout time delay cannot be reset. After the
time delay is completed, the unit automatically resets.

Timer - Lockout
TL Series
The TL Series provides protection against short
cycling of a compressor. At the end of each
operation, or whenever power is lost, a lockout
delay is initiated. This lockout delay prevents
restarting of the compressor until the head
pressure has equalized. Compressor relay chatter
due to thermostat bounce is eliminated by use
of optional one second delay-on-make. The TL
Series should not be used with cooling anticipator
resistors or solid-state switches. (See the TA
Series) .
Connection:
L1
Operation (Lockout):
Lockout: On initial closure of S1, the compressor relay
energizes immediately (or after an optional 1 s delay).
When the S1 opens or input voltage is interrupted, the
output opens and remains open for the lockout time delay.
During this lockout time delay period, the compressor
relay cannot be re-energized.
Reset: The lockout time delay cannot be reset. After the
time delay is completed, the unit automatically resets.

Timer - Delay-on-Make/Delay-on-Break
The CT Series combines a delay-on-make and
delay-on-break time delay into one unit and
may be used to control fan delays in heating
and/or cooling equipment. The CT includes
bypass circuitry to allow it to operate with cooling
anticipators ≥ 3000 ohms. It is designed to operate
in 24VAC control circuits. Several CT modules
may be combined to provide sequencing on of any
number of loads and sequencing off of the same
loads, such as electric heating elements.
Connection:
L1
N
Operation (Delay-on-Make/Delay-on-Break):
Forced Air Heating or Air Conditioning (as shown): When
the thermostat closes, the compressor relay is immediately
energized. At the end of a fixed delay-on-make delay (T1),
the fan relay is energized. When the thermostat opens,
the compressor relay is de-energized and the delayon-break delay is initiated. On completion of the fixed
delay-on- break delay (T2) the fan relay is de-energized.
If the thermostat is reclosed during the delay-on-break
delay, the delay-on-break delay is reset and the fan relay
remains energized. If the thermostat is closed when
input voltage is applied, the delay-on-make delay (T1)
begins as normal .
Reset: Removing input voltage resets the output and
time delays .

Timer - Vending
HRV Series
The HRV combines the accuracy of microcontroller
based circuitry with an electromechanical relay
output. The HRV’s switching capacity allows
direct control of loads like compressors, pumps,
motors, heaters, and lighting. The HRV “S” version
provides a vend time after the selected number
of initiate switch closures to start is reached. The
HRV “A” version includes all of the “S” features
and allows the total vend time to be extended for
each additional initiate switch closure. The HRV is
ideal for cost sensitive single coin or token vending
machines. The electronic circuitry is encapsulated
to protect against humidity and vibration.

Operation
Coin Totalizer & Vending Timer (“S” Version):
Input voltage must be applied prior to & during operation.
When the total number of S1 initiate switch closures
equals the number to start set on the lower 3 DIP switches,
the load energizes and the vending time set on the upper
7 DIP switches begins. At the end of the vending time, the
load de-energizes and the vending time is reset. Closing
the initiate switch during vend timing will have no affect
on vend time delay.
Accumulating Vending Timer (“A” Version):
Input voltage must be applied prior to & during operation.
When the total number of S1 initiate switch closures
equals the number to start set on the lower 3 DIP switches,
the load energizes and the vending time starts. For every
initiate switch closure, the HRV unit adds one time per
coin period, as set on the upper 7 DIP switches, to the
total vending time.
Operation Note: If S1 is closed when input voltage is
applied, the output remains de-energized and the S1
counter remains at zero closures. At least one “vend
time” and one “closures to start” DIP switch must be in
the “ON” position for proper operation.
Reset: Removing input voltage resets the vend time delay,
the S1 closure counter, and de-energizes the output relay.
