The CLP2FA1B115 is a 2-point level controller relay designed to monitor and control the levels of conductive liquids. It operates on a rated voltage of 115 VAC and features an adjustable sensitivity range from 250Ω to 500kΩ, driving an 8A/250 VAC SPDT relay output. The device includes LED indicators for power and output status and is designed for easy installation via an 11-pin circular plug. This controller is suitable for both filling and emptying control applications, and multiple units can be connected in series for cascade coupling to monitor more than two levels.
