Designed as a high-reliability earth leakage sensor, this unit continuously monitors the isolation resistance between the 24VDC power system and the protective earth. The \u003cstrong\u003eHoneywell FC-TELD-0001\u003c\/strong\u003e features conformal coating (indicated by the CC designation) to ensure long-term stability and resistance to corrosive, humid, or dusty industrial atmospheres. By alerting control systems of leakage currents before they escalate into full ground faults, this sensor prevents unexpected safety system trips and maintains high operational availability in critical process environments.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul style=\"list-style-type: square;
