The Macromatic TR-6512U is a Repeat Cycle ON Time Delay Relay. This programmable multi-range plug-in relay has a universal input voltage of 24-240V AC & 12-125V DC at 50/60Hz, with 10A DPDT output contacts. It has 16 built in time ranges, from 0.05 sec to 100 hours, using rotary switches. Settings within the time range are made using the potentiometer switches. The ON & OFF times are set separately. The ON time occurs first. The TR-6512U uses an 8 pin 70169-D octal socket. This relay replaces TR-65121, TR-65122, TR-65126, & TR-65128. Note: Image is an approximation. Actual part may differ.

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.
