contact output modules offer either normally-open (Form A) or
normally-closed (Form B) configurations. You can select the form
configuration for four of the contact output modules, the 1771-OW,
-OW16, -OWN, and -OX. The 1771-OW has eight selectable
outputs. The 1771-OW16 has eight normally-open and eight
selectable outputs. The 1771-OWN has 32 selectable outputs.The
1771-OX has four selectable outputs. Selectable–configuration
means you can predetermine whether an output will be on or off
when local power is lost to the control system or the output module.
The 1771-OWNA has 32 non-selectable normally-open contacts.

Isolation helps assure that a failure on one
output circuit does not pull down another output circuit, thus
increasing overall system integrity. This isolation also protects the
backplane logic from line transients on the output circuits.
!" You can apply either ac or
dc voltages to relay contact output circuits. The range of these
voltages can be broad (within the module’s operating specifications)
without impacting the module’s performance.
Contacts on relays permit dc outputs to be
sinking or sourcing as required by the devices being controlled.
Solid-state outputs require specific compatibility with the load
device as to current sinking or sourcing.
" You can use analog module
inputs for different devices by switching circuits through relays.
Analog signals are typically low voltage (+10V dc) and low current
(4-20 mA). Contact resistance can be critical, and should be
accounted for in low-impedance circuits.
This publication provides you with information about
Allen-Bradley’s relay contact output modules. The publication is
divided into two sections. The first section contains general
information that pertains to all of the relay modules; the second
section contains module-specific information. The following table
lists the relay contact modules and the page number on which you
can find information about each.

Allen-Bradley relay contact output modules use one of the following
relay types:
$ +)'% "&#$
)-. ),)-. ++ .
.
.
.
. .
.
Electromechanical relays contain the most economical design for
power applications. These modules typically can handle line surges
and noise through closed contacts. Electromechanical relays are not
recommended for low voltage/low current applications.
Electromechanical relays are generally slower than dry-reed relays.
They are not recommended for use in environments with
contaminants such as acid, ammonia, nitrogen, or chlorine (noxious
environments) because they are not hermetically sealed.
Allen-Bradley modules that use electromechanical relays include the
1771-OW, 1771-OW16, 1771-OWN, and 1771-OWNA modules.
Dry-reed relays are noted for their speed. These relays are
well-suited for low-voltage, low-power applications. They are
hermetically sealed and thus offer protection in noxious
environments. Dry reeds, however, cannot handle surge currents due
to their low-voltage design. Allen-Bradley modules that use
dry-reed relays are the 1771-OYL and 1771-OZL modules.
The mercury-wetted relay is a power version of the dry-reed switch.
These relays feature long life and high contact reliability because the
mercury re-coats the contacts on every operation. Mercury-wetted
relays are also hermetically sealed and have no bounce on outputs
and offer a clean switch. Of the three types of relays,
mercury-wetted relays are the slowest (10 ms). ATTENTION: The
1771-OX module contains mercury-wetted relays. At the end of the
equipment's life, it should be collected separately from any unsorted
municipal waste.

Relay contact output modules receive power through the 1771 I/O
chassis backplane from the chassis power supply. Refer to the
module specifications on pages 11 through 24 for the current
required from the power supply (in mA) to operate the module. You
should total the current requirements for all the modules in the
chassis to avoid overloading the power supply or the I/O chassis
backplane.
Plastic keying bands shipped with each I/O chassis let you configure
your I/O slots to accept only one type of module. You can configure
any backplane connector in an I/O chassis to receive your contact
output module except for the leftmost connector, which is reserved
for adapter or processor modules. Since mixed voltages are often
used on relay modules, most of the contact output relay modules all
have the same keying slots. Refer to the module specifications for
specific keying positions.
Status indicators on the front of each module show the system logic
side status of the output relays. Each module has one indicator per
output. When the indicator is on, it means the output relay coil is
energized; when the indicator is off, it means the output relay coil is
not energized. You can quickly isolate many types of external
hardware-related faults by comparing these indicators with their
corresponding output devices, and the control program.

When using relay contact output modules, you must consider the
following:
Relays have a finite number of operations during their life. This
varies depending on the current loads and voltages you apply relative
to the relay’s design specifications. A relay that is always operating
at the same load conditions has a very predicatable life. A low power
load delivers longer contact life when the minimum load conditions
are met. Varying load conditions can drastically shorten contact life.
Do not operate a contact at low current or voltage conditions after
operating the same relay under high power conditions. Operate at
low power first, then at high power.
Electromechanical relays typically have a longer life than dry-reed
relays. When selecting a relay type, we recommend that you
consider the number of operations expected over time and the load
placed on the relay.
The switching frequency of a relay is limited by its mechanical
characteristics. To obtain maximum relay life, do not exceed the
maximum switching frequency of the module.
All types of relay outputs have a specified time in which contact is
made or broken (pull-in or drop-out times). Dry-reed relays are
notably faster than electromechanical. Electromechanical and
dry-reed relays have contact bounce. Mercury-wetted relays do not
have bounce.
All wiring between the module and the load creates a certain amount
of capacitive loading for the relay contacts. This capacitance is
discharged during contact closure. The resulting peak current flow
causes additional wear of the contact. Avoid this effect by keeping
your cable lengths as short as possible, and, if possible, insert a
resistor in series with your load. Locate the resistor as near as
possible to the field wiring arm. Size the resistor properly.

1771 Digital I/O Relay Contact Output Modules
Many loads (relays, coils, motor starters, solenoids, motors, etc.)
contain a certain amount of inductance. This inductance does not
allow an instantaneous change of current when the relay contacts
open. As a result, the voltage across the contacts rises to a very high
level, and causes arcing between the contacts. This arcing reduces
the life of the contacts.We recommend you use a resistor-capacitor
(RC) network (also called a “snubber”) across the contacts in all
circuits.
ATTENTION: Failure to use a resistor-capacitor
(RC) network across the relay contacts can result in
generation of electromagnetic noise which could
disrupt nearby electrical equipment, including the 1771
I/O chassis.
!
The best location for the RC network is across the relay contact
terminals on the field wiring arm. This location suppresses the noise
where it is generated, and does not let the noise radiate along the
wiring going to the load.
The 1771-OW, -OW16, -OWN, -OWNA, -OYL, and -OZL modules
are not approved by UL/CSA for use with reactive loads. The
1771-OX module is designed with selectable dc surge protection
circuitry.
The formula necessary to determine the appropriate values for the
RC network is shown below. Use a capacitor with an ac voltage
rating greater than the maximum voltage seen across the contacts.
Use a 5%, 1 Watt carbon composition resistor.

Incandescent lamps also create a spike due to their low turn-on
resistance before they become hot. Therefore, you must use derating
or surge suppression (for example Allen-Bradley surge suppressors
1492-H2K120, 1492-H2K024, and 1492-H2K240). Specified relay
current is typically derated at ten times the steady-state current of the
incandescent lamp load. For derating, you can calculate cold-start
load by measuring the cold load resistance. You can also experience
large current surges when bulbs burn out (e.g. 20-50 amps).
The operating temperature of the relay greatly influences the life of
the relay contacts. The 1771 relay contact output modules have a
maximum operating temperature of 60o. Operation at lower
temperatures will extend relay contact life.
Since electromechanical relays are not hermetically sealed, they are
not recommended in environments with contaminants such as acid,
ammonia, nitrogen, and chlorine— especially with voltages under
24V ac/dc or for prolonged periods without operation. Such
environments contaminate the relay contacts, causing reliability
problems. Higher voltage usage, between 24 and 120V ac/dc, and
continued operation help keep contacts clean as a result of the
burning off of contact contaminants. Relays are also subject to
reliability problems under high vibration environments as
mechanical motion can intermittently break contacts.
Mercury-wetted relays and dry-reed relays are hermetically sealed
from the environments, thus preventing environmental reliability
problems. Mercury-wetted relays are generally sensitive to
mounting position.
The life of the relays in the output modules is directly affected by the
load through the contacts and the operating temperature.
Minimum currents and voltages specified for 1771 relay contact
output modules are selected to provide clean contacts throughout the
life of the contacts. The relays can operate below the minimum
specifications, but operation will not be reliable.
Exceeding the maximum power ratings for the module will shorten
the life of the relay contacts. Do not operate relay contact output
modules at power levels greater than maximum specifications.
By using the operating range graphs, you can determine if you are
within the operating capability of the relay. You only need to know
any two of the following:
• voltage
• load current (mA)
• load power consumption (W)

Using Figure 1, follow this example:
Given a 30V dc, 4W indicator, is this in operating range?
1. Locate the vertical line for 30V.
2. Locate the angled line for 4W; it is at this angle (\).
3. Find where the two lines cross. If this is within the shaded area
of the graph, you are in the permissible operating area for the
relay contact output module. (In this example, you are in the
permissible operating range.)
Refer to the following operating range graphs to determine the
operating capability of the relay.

1771ĆOW modules do not contain surge limiting circuitry. Use
these modules for switching resistive loads only (e.g., lamps, indicators,
heating elements). They are not recommended for inductive or capacitive
loads (e.g., motor starters, solenoids, relays).
Outputs on the 1771ĆOW module are arranged in 4 groups of 2,
each group with its own common. Each output is electrically isolated from
module logic circuitry. The module can simultaneously switch all 8 outputs
to separate loads, each conducting a maximum load of 1.0A continuously,
at rated power. AC loads switched by the modules should have a power
factor of 1.0.
You can use the 1771ĆOW module to drive
an input of the following ac modules: 1771ĆIA, ĆIA2, ĆIAD, ĆIAN, ĆID, ĆID16,
ĆIN, ĆIND. The 1771ĆOW module can drive an input of the following dc
modules at nominal voltage: 1771ĆIB, ĆIBD, ĆIBN, ĆIH, ĆIQ, ĆIQ16, ĆIT, ĆIV,
and ĆIVN. For reliable operation, a load current of at least 10mA should be
maintained.
. Do not attempt to increase load
current or wattage capability beyond the rating by connecting two or more
outputs in parallel. The slightest variation in output relay switching time may
cause one set of the contacts to switch the total load current.

" 1771ĆOW16 modules do not contain surge
limiting circuitry. With properly chosen surge limiting devices,
this module can be used to switch resistive (e.g., lamps,
indicators, heating elements), capacitive and inductive loads
(e.g., motor starters, solenoids, relays). When driving
inductive or high current loads, a resistorĆcapacitor network
should be placed across the module's relay contacts at the
field wiring arm. This will help reduce the generation of
electromagnetic noise created by the contacts when
changing state.
. Outputs on the 1771ĆOW16 module are
arranged in 2 groups of 8. Each output has a separate
common and is electrically isolated from module logic
circuitry. The first group of outputs are arranged as
normallyĆopen contacts. The second group of outputs are
selectable normallyĆopen or normallyĆclosed. The module
can simultaneously switch all 16 outputs to separate loads.
Each output can conduct a maximum load of 2.0A
continuously at 500VA for ac loads, and 80W maximum for
dc loads, but the total output power of the module cannot
exceed 1440VA or 1280W.
You can use the
1771ĆOW16 module to drive an input of the following ac
modules: 1771ĆIA, ĆIA2, ĆIAD, ĆIAN, ĆID, ĆID16, ĆIN, ĆIND.
The 1771ĆOW16 module can drive an input of the following
dc modules at nominal voltage: 1771ĆIB, ĆIBD, ĆIBN, ĆIH, ĆIQ,
ĆIQ16, ĆIT, ĆIV, and ĆIVN. For reliable operation, a load current
of at least 10mA should be maintained.
. Do not attempt to
increase load current or wattage capability beyond the rating
by connecting two or more outputs in parallel. The slightest
variation in output relay switching time may cause one set of
the contacts to switch the total load current.
When the output image
table bit at the address corresponding to any output is
energized (set to 1), the corresponding relay contact is
closed or opened, respective to the jumper setting.

An individual output should not be subjected to high power loads and then be required to run low power loads.
Output current maximum per module is limited by the maximum output power rating.
14 gauge wire connected to all terminals may not allow the field wiring arm cover to close. A smaller wire size
may be required.

" 1771ĆOWN modules do not contain surge limiting circuitry.
Use these modules for switching resistive loads only (e.g., lamps,
indicators, heating elements). They are not recommended for
inductive or capacitive loads (e.g., motor starters, solenoids, relays).
. Outputs on the 1771ĆOWN module are arranged in 4 groups
of 8, each group with its own common. Each output is electrically
isolated from module logic circuitry. The module can simultaneously
switch all 32 outputs to separate loads, with a maximum of 12A per
module. Each output can conduct a maximum load of 1.0A
continuously at 30W maximum. AC loads switched by the modules
should have a power factor of 1.0.
You can use the 1771ĆOWN
module to drive an input of the following ac modules: 1771ĆIA, ĆIA2,
ĆIAD, ĆIAN, ĆID, ĆID16, ĆIN, ĆIND. The 1771ĆOWN module can drive
an input of the following dc modules at nominal voltage: 1771ĆIB,
ĆIBD, ĆIBN, ĆIH, ĆIQ, ĆIQ16, ĆIT, ĆIV, and ĆIVN. For reliable operation,
a load current of at least 10mA should be maintained.
. Do not attempt to increase
load current or wattage capability beyond the rating by connecting two
or more outputs in parallel. The slightest variation in output relay
switching time may cause one set of the contacts to switch the total
load current.
When the output image table bit
at the address corresponding to any output is energized (set to 1),
the corresponding relay contact is closed or opened, respective to
the jumper setting.
All outputs are individually selectable for either normallyĆopen or
normallyĆclosed operation. They are preset for normallyĆopen
operation at the factory. See next page for relay output jumper
settings.

recommended for inductive or capacitive loads (e.g., motor
starters, solenoids, relays).
The 1771ĆOYL module has 4 normallyĆopen (Form A)
and 4 normallyĆclosed (Form B) relays. Outputs are arranged in 4
groups of 2, each group with its own common. Each output is is
electrically isolated from module logic circuitry. The module can
simultaneously switch all 8 outputs to separate loads, each
conducting a maximum load of 100mA continuously at rated
power. AC loads switched by the modules should have a power
factor of 1.0.
You can use the 1771ĆOYL
module to drive an ac input module up to 24V ac. The 1771ĆOYL
module can drive an input of the following dc modules: 1771ĆIB,
ĆIBD, ĆIBN, ĆIG, ĆIGD,ĆIH, ĆIN, ĆIND, ĆIQ, ĆIQ16, ĆIT, ĆIV, and ĆIVN.
Do not attempt to increase
load current or wattage capability beyond the rating by connecting
two or more outputs in parallel. The slightest variation in output
relay switching time may cause one set of the contacts to switch
the total load current.
