Lead Time: 10 Days
Description Of Function
Upon application of input voltage, the time delay relay is ready to accept a trigger. When the trigger is applied, the output remains de-energized. Upon removal of the trigger, 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.

Approvals
Operation
Time-based control with high amperage switching allows effective and economical operation of heavy loads such as pumps, compressors, and heaters. This cost-effective solution can eliminate the need for a separate contactor reducing cost and saving space. Choose from adjustable on-board potentiometers, remote potentiometers, or factory-set fixed time delays.
