The Macromatic TR-6612U is a Delayed Interval 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 a certain time range are made using the potentiometer switches. The TR-6612U uses an 8 pin 70169-D octal socket. This relay replaces TR-66121, TR-66122, TR-66126, & TR-66128. Note: Image is an approximation. Actual part may differ.

The Delayed Interval works in a similar fashion to the Repeat Cycle with one exception. The OFF time delay starts along with the input voltage. After that, the ON time delay starts and the relay is energized for the duration of the time delay. When the ON time delay finishes, the relay de-energizes. The input voltage has to be re-introduced to restart the cycle, as opposed to a Repeat Cycle, which will continue on its own.
