Guide to Ground Fault Sensing

With electromechanical relay outputs, the operation is the same. In normally energized versions, the output relay is energized with sensor power applied, so the contacts change state when the sensor has power. The relay will then return to shelf state when there is a loss of power to the sensor, or the fault current exceeds the trip point.
