Timing Mode: DELAY ON MAKE
Category: SOLID STATE TIMER
Series: THCU-E
CUBE SOLID STATE, UNIVERSAL AC/DC WIDE VOLTAGE, DIPSWITCH
THCU Timer
THCU is a universal AC/DC voltage solid state
timer in a compact 2" x 2" configuration. This unit
features wide operating voltages: 19 to 265 VAC
and 10 to 120 VDC.
THCU-E offers three time ranges: 0.1 second to
102.3 seconds in 0.1-second increments,1 second
to 1023 seconds in 1-second increments, or 10 to
10230 seconds in 10-second increments. Tenposition binary dipswitch is easy to program.
Advanced digital circuitry provides this timing
module with unsurpassed accuracy and reliability.
Available with factory-fixed time as THCU-C.
Timing Mode
ON
INPUT
VOLTAGE
Application of input voltage to the timer starts the time delay.
At the end of the delay period, the load is energized.
To reset, remove the input voltage to the timer.
