Why Choose the Carlo Gavazzi CLD4MA2D230 Conductive Level Controller?
The Carlo Gavazzi CLD4MA2D230 is a multifunction 2 to 4-point conductive liquid level controller designed for DIN rail installation in industrial control panels. Part of the Carlo Gavazzi CL series, it uses up to five connected probes to monitor electrically conductive liquids and provide automatic filling, emptying and high/low level control.
This version operates from a 230 V AC supply and provides SPDT + SPST-NO relay contacts. Its 250 Ω to 500 kΩ sensitivity range allows the controller to work with conductive liquids having a broad range of conductivity characteristics, while relay contacts rated at 8 A at 250 V AC provide practical switching capability for industrial control circuits.
The CLD4MA2D230 is housed in a compact 35.5 × 81 × 60.2 mm enclosure with screw terminals and IP20 protection. Its multifunction architecture is particularly useful for pump control, tank filling and emptying, and applications requiring maximum and minimum level monitoring across interconnected liquid systems.

Reliable Multifunction Conductive Liquid Level Control
Conductive level controllers detect liquid by monitoring electrical conductivity between installed electrodes. The Carlo Gavazzi CLD4MA2D230 provides 2 to 4-point control using five probe inputs, allowing it to perform more advanced filling, emptying and high/low monitoring functions than basic single-point level relays.
The multifunction design can also support maximum and minimum control between two liquid systems, such as transferring the same conductive liquid from one tank to another using a common pump. Its 230 V AC supply, relay outputs, wide sensitivity range and DIN rail format make the CLD4MA2D230 well suited to automated pumping, water handling and industrial process installations.
Typical Applications
- Automatic tank filling and emptying.
- High and low liquid-level monitoring.
- Pump start and stop control.
- Tank-to-tank liquid transfer.
- Well and reservoir level monitoring.
- Overflow prevention systems.
- Dry-running protection control systems.
- Industrial water handling equipment.
- Conductive process-liquid monitoring.
