The automatic level control units of the DHC1Y-xx series are intended for mounting on pumping control
panels. They do not use any additional sensors, but conductive probes to contact the liquid. The unit
sends low (harmless) voltage signals to the probes and once a contact between a probe and liquid is established, the unit changes its contactors’ state. Units are available in three variants with different number of control contacts suitable for different applications.
Each contact can transfer current of up to 5A, which is enough to ensure control over the powerful pumps’ contactors or to directly control pumps with mounted power of 1 kW. The automatic level control units can be installed on a DIN rail.
