This module continuously evaluates DC distribution systems to detect active ground faults before they escalate into systemic failures or hazardous plant shutdowns. Operating on a nominal 24 VDC power supply, the unit maintains a balanced earth reference of -12 VDC under normal, non-fault operating conditions. Any electrical current imbalance on the DC loop is registered by the internal monitoring circuitry, triggering an output relay once the current leakage exceeds a predefined threshold limit.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #1a365d;
