The Macromatic THR-12268-37 is a single shot falling edge Time Delay Relay. This encapsulated relay has an input voltage of 24V AC/DC. It has an adjustable time range of 10 to 1000 minutes. Time is adjusted by turning the blue dial 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 a Single Shot Falling Edge, the relay de-energizes when the trigger is implemented. Taking away the trigger energizes the relay and begins the time delay. After the time delay, it de-energizes again, and needs the trigger introduced and taken out to re-energize. Adding and taking away the trigger before the time delay ends will keep the relay energized.
