Description
The EQ2220GFM Ground Fault Monitor provides ground fault monitoring in a system that includes a floating 24 Vdc power source. The device detects ground fault conditions on +/– power and all secondary I/O circuits. A positive or negative ground fault condition is indicated immediately by local LEDs, and by a relay contact after a 10 second time delay. The ground fault monitor is intended to be mounted in the same enclosure as the controller.
