LCP2C250 Macromatic Relays, LCP Series

• Controls Level of Conductive Liquids in Pump Up (Fill) or Pump Down (Drain) Applications
• Probe is Pulsed with a DC Voltage to Prevent Electroplating
• Factory‑Fixed Time Delay of 1‑60 Seconds Prevents Rapid Cycling

LCP Series Liquid Level Control Relays detect and control levels of conductive liquids (tap water, seawater, sewage, chemical solutions, coffee, ice cream, etc.) in single probe pump up or pump down applications. The conductive properties of the liquid complete a circuit between a probe and common when the liquid encounters both. These relays compare the value of the measured resistance between probes with the setpoint of the adjustable potentiometer provided on the product. The output of the relay is used to control pumps, solenoids, or valves to lower, raise or maintain the level of the liquid in the tank. Probes are pulsed with a DC voltage to prevent potential electroplating issues. A built‑in time delay prevents rapid cycling.

• Two Adjustable Sensitivity Ranges
• LED Status Indication
• Uses industry‑standard 8 pin octal socket
