This handy device allows you to switch devices with low voltage contacts on and off with any of our plug-in controllers. Safe, reliable, power sensing relay monitors AC voltages from 90-140VAC and triggers a relay, but it is more than a relay in a box. Includes a de-bounce circuit and overcurrent breaker for safety and has both normally-open and normally-closed contact for versatility. Comes with 18" power cord with 2 prong plug.

Common Use Example
You can control a gas heater with 24v or millivolt controls and a 120v fan system with the same controller. Just plug this power control relay into the controller's heating outlet, and wire the heater's thermostat terminals to the screw-down contacts on the relay. When the controller sends power to the heating outlet, the relay will activate the heater.
