Off-Delay Relay Output

OPERATION

Voltage is continuously applied to the input. An external isolated switch controls the

timer. When closed, the relay energizes. Opening the switch initiates the delay period.

Upon completion of the delay period, the relay de-energizes. If the control switch

recloses during the delay period, the relay remains energized and the timer resets

to zero.
