The Macromatic THR-11668-35 is an 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 hours. 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 the Off Delay function, the relay energizes once the trigger is implemented. The time delay only starts once the trigger is taken out. After the time delay ends, the relay de-energizes. Re-introducing the trigger before the time delay finishes resets it, preventing the relay from de-energizing. The input voltage needs to be in place for the trigger to be successfully introduced Macromatic THR Series Relay Installation Instructions
