THCU Timers
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. Ten-position 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.

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.
