The Macromatic THR-15168-34 is a repeat cycle ON Time Delay Relay. This encapsulated relay has an input voltage of 24V AC/DC. It has an adjustable time range of 0.1 to 10 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 this Repeat Cycle function, once the input voltage is introduced, the relay energizes and the ON time delay starts. After the ON time delay, the relay de-energizes for the duration of the OFF time delay. The cycle then starts over again with the ON time delay and the relay is energized. The cycle will repeat until the input voltage is taken out.
