The CLP2FA1BM24 is a 2-point level controller with cascade coupling designed for conductive liquid level detection in filling or emptying applications. It features adjustable sensitivity ranging from 250O to 500kO, with three selectable ranges (Low, Standard, and High sensitivity) to accommodate various probe configurations and cable capacitances. The device operates at rated voltages of 24 VAC/DC (19.2 to 28.8 V), with an 8A/250 VAC SPDT relay output, LED indicators for power and output status, and a response time of 1 second for both ON-OFF and OFF-ON transitions. Installation is simplified through an 11-pin circular plug connector, and up to 7 units can be cascaded for multi-level detection in a single tank. This controller is ideal for industrial tank monitoring, pump control, and process automation systems requiring reliable conductive level sensing.
