Direct current power supply 12÷28Vdc.
The sensor may be connected:
To the Hydrovar
®
directly on the terminal board X3. The sensor opens the NPN contact (black wire) 10
seconds (factory setting) after the water lack signal.
To a monitoring system (PLC), directly on the terminal board. A load resistance (pull-up) with a minimum
value of 1kOhm must be fitted on the outside.
To a system with a relay and direct current power supply. A recirculating (free-wheeling) diode must be
fitted on the outside.
General use, power supply 21÷27Vac.
The sensor may be connected to a system with a relay and alternating current power supply.
