The HRN-36 Monitoring Relay is used to monitor the voltage level in a DC supply range. The monitored voltage is also the supply voltage. It is possible to set 2 independent levels with the relay.
To avoid short-term peaks, there is a delay that can be set in the range 0.5-10s. This comes into effect when the device switches from the normal state to the fault state and avoids unnecessary switching of the output relays. When resetting to the normal state, this delay no longer comes into effect, but the hysteresis (5%) does. The changeover contacts provide further configurations and functions depending on the current requirements of the application.
