The automatic level control units of the DHC1Y-xx series are intended for installation in the pumping control panel. They do not use additional sensors, but conductive probes for contact with the liquid. The unit sends low (harmless) voltage signals to the probes, and once contact is made between a probe and liquid, the unit changes the state of its contacts. The units are available in three variations with a different number of control contacts suitable for different applications:

• Each contact can carry a current up to 5A.
• Ensure control of powerful pump contacts.
• Capability for direct control of pumps with an assembled power of 1 kW.

The automatic level control units can be mounted on a DIN rail.
