The Macromatic LCP1D250 is a dual probe pump up liquid level control relay. This 8 Pin plug-in relay has an input voltage of 240V 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. Can cross to products from SSAC & NCC Note: Image is for reference, actual part may differ.
