FC-TELD-0001 Earth Leakage Detector Honeywell

FC-TELD-0001 Earth Leakage Detector Terminal (TELD)

Overview: The FC-TELD-0001 is an Earth Fault Monitor engineered to identify earth faults within connected circuits in a power supply group. It elevates earth voltage to approximately +4Vdc, relative to the monitored power supply group's 0Vdc. The drawn current (0-20mA) offers insights into the nature of the earth fault present. In normal conditions, it consumes around 10mA, varying in the presence of an earth fault based on its magnitude and polarity. The module can be deactivated by the control system, isolating it from the earth pin and effectively eliminating the earth fault current.
