The Macromatic TR-6182U is a power triggered Watchdog 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. Precise settings within the time range are made using the potentiometer switch. The TR-6182U uses an 11 pin 70170-D octal socket. This relay replaces TR-61821, TR-61822, TR-61826, & TR-61828. Note: Image is an approximation. Actual part may differ.

With the Watchdog function, the output is energized and the time delay starts through the use of a trigger. In this case, voltage is used as a trigger. The relay becomes de-energized once the time delay stops. Re-introducing the trigger before the time delay stops keeps it energized for another cycle. The unit can stay energized for as long as it's needed, provided that the trigger is implemented before the time delay ends. Input voltage must be in place before the trigger and time delay can take effect.
