HVR272 - High Voltage Relay

Product Diagram

The signal powered High Voltage Relay HVR272 is used to monitor critical voltage levels ( low or high) up to 700Vac/dc. Typical applications include;

  • Field excitation on DC motors
  • Over voltage monitoring on 600Vdc systems.

The unit has two independent relay contact outputs which can be used for system shut-down and PLC or DCS inputs. Both the relays are energised with voltage present and can be configured for NO or NC contacts.

Trip status is indicated by a red LED. Trip point can be adjusted by a 15 turn trim pot accessible from the front of the unit.

The HVR272 is powered from the voltage being monitored.
