A timer relay is required to operate a circuit, machine or mechanism for a certain period of time. The ELO Countdown Timer Relay w/ Delay does not give output immediately after it has been triggered. It starts counting the front-end time first. Once the specified countdown time is over, the relay gives an output until trigger is cut off. Once the trigger is off, it continues to give output for the duration of back-end delay period. If the relay recieves a trigger before the back-end countdown period is over, the output continues without interruption and the back-end timer is reset to 0.

Both times (front-end and back-end) are adjusted by ELO according the customer specifications. The front-end can have 3 different options where the back-end time needs to be fixed. When there is no specific customer time requests, the standard times for delay time are 1,  and 3 minutes, where the output time is 1 minute.
