The Macromatic LCP2B250F20 is a single probe pump down (drain) 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.) in a tank. Sensitivity is adjustable within the set range. Used to monitor liquid levels in the tank for pumps, solenoids, or valves. Electroplating is prevented due to the DC voltage pulsed through the probe, while the fixed time delay prevents rapid cycling. Pilot duty rating.

When the level of conductive liquid goes above the probe, the fixed time delay starts and the LED flashes red. The relay energizes after the time delay and the LED is solid red. It stays this way until the liquid drains below the level of the probe. The relay is then no longer energized and the LED is green.
