    Battery Voltage Guard BW500

    The BW500 is designed for monitoring of battery voltages. Under-voltage or over-voltage can be selected.

    The relay switches off, if the voltage falls under the limit value and if the delay time ran off. If the voltage exceeds the limit value + hysteresis, the relay will be activated.

    The relay switches on, if the voltage exceeds the limit value and if the delay time ran off. If the voltage falls under the limit value - hysteresis, the relay will be deactivated.
