The Macromatic LCP2C100 is a dual probe pump up liquid level control relay. This 8 Pin plug-in relay has an input voltage of 120V AC. It monitors the level of conductive liquid, (such as tap water, chemical solution, seawater, etc.) and compares the resistance between the probes. Used to monitor liquid levels in the tank for pumps, solenoids, or valves. Pilot duty rating. Sensitivity is adjustable. Can cross to products from SSAC and NCC.

Additional Product Information

When the level of conductive liquid drops below the low probe, the relay is energized and the LED is red. It stays energized until the level of liquid hits the high probe. The LED then turns green and the unit de-energizes until the liquid goes back under the low probe.
