The Macromatic THR-14168-31 is an on/off delay Time Delay Relay. This encapsulated relay has an input voltage of 24V AC/DC. It has an adjustable time range of 1 to 100 seconds. Time is adjusted by turning the blue dials at the top. The encasement of the unit is made for use under harsh conditions. The design is microprocessor-based to provide better functionality, and is perfect for high volume OEM applications.

With the On/Off Delay function, the T1 time delay starts when the control voltage is present and the trigger is introduced. The relay energizes after the time delay and stays energized for the duration of the T2 time delay. Afterward the relay is de-energized until another trigger is introduced. If the trigger is removed during T1, it stays de-energized and the time delay resets. If the trigger is re-introduced during T2, the relays stays energized and the time delay resets.
