The Macromatic TR-6312U is a Repeat Cycle OFF 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 a rotary switch. Adjustments within the time range are made using the potentiometer switch. The ON & OFF times can be set separately. The OFF time occurs first. The TR-6312U uses an 8 pin 70169-D octal socket. This relay replaces TR-63121, TR-63122, TR-63126, & TR-63128. Note: Image is an approximation. Actual part may differ.

This Repeat Cycle function means that once the input voltage is introduced, the OFF time delay starts. The relay energizes after this time delay, and stays energized during the ON time delay. After the ON time delay the relay de-energizes and the cycle repeats itself until the input voltage is taken out.
