GE IS200ERGTH1AAA EX2100 Excitation System Terminal Board

Product Description

GE IS200ERGTH1AAA (ERGT) is an exciter regulator ground detector terminal board for Speedtronic Mark VI / EX2100 excitation control systems. It acts as a dedicated signal interface between the EROC exciter regulator option card and third-party ground fault detectors. This module converts signals from the 9-pin connector of the EROC board to screw terminal connections. It supports connection to third-party ground detectors and provides three monitoring outputs: ground alarm, detector fault and diode fault. It monitors insulation and ground faults on the generator excitation circuit in real time, which is a critical spare part for excitation protection of gas turbine and steam turbine generator units.
