The Macromatic LCP8D100 is a dual probe pump down liquid level control relay. This 8 Pin plug-in relay has an input voltage of 24V 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 & NCC.

Additional Product Information

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