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.
