Why Choose the Carlo Gavazzi CLD4MA2DM24 Conductive Level Controller?
The Carlo Gavazzi CLD4MA2DM24 is a versatile 2-to-4-point conductive liquid level controller designed for filling, emptying and multifunction level-control applications involving electrically conductive liquids. Part of the Carlo Gavazzi CL series, it supports up to five input probes, offers a sensitivity range of 250 Ω to 500 kΩ and provides SPDT + SPST relay outputs from a compact DIN-rail housing.
The CLD4MA2DM24 is designed for applications where several liquid-level points must be monitored and controlled. Its multifunction configuration can support filling and emptying arrangements, including applications where maximum and minimum levels are controlled using conductive probes positioned within tanks, wells or reservoirs.
Operating from a nominal 24 V AC/DC supply, the controller provides relay contacts rated up to 8 A at 250 V AC. Screw-terminal connections, LED status indication and a compact 35.5 × 81 × 60.2 mm housing simplify installation in industrial control panels.

Reliable Multi-Point Control of Conductive Liquid Levels
Conductive level controllers detect liquid by measuring electrical conductivity between sensing probes positioned at selected levels. The Carlo Gavazzi CLD4MA2DM24 can use multiple probes to monitor different level points, allowing pumps, valves or associated control equipment to respond when the conductive liquid reaches predetermined positions.
The multifunction design supports filling and emptying control and can be configured for more advanced tank and well applications. Its broad 250 Ω to 500 kΩ sensitivity range enables use with a variety of conductive liquids, while the SPDT + SPST relay arrangement provides flexible switching for industrial control circuits.
