The Macromatic TR-51321-18 is a time delay relay with 2C DPDT output and rated 10 A at 240 V AC, 10 A at 30 V DC, driven by a 240V AC input.
It is adjustable from 1.8 to 180 min and set by an onboard knob.
It is a Watchdog timer.
Upon application of control voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the output is energized and the time delay (t) begins. At the end of the time delay (t), the output is de-energized unless the trigger is removed and re-applied prior to time out (before time delay (t) elapses). Continuous cycling of the trigger at a rate faster than the time delay (t) will cause the output to remain energized indefinitely.
It is started by a control switch.
It has Socketable mounting and Plug In terminals.
