GE IS200EAUXH1AAA Excitation Control System Interface Board

Product Description

GE IS200EAUXH1AAA (EAUX Board) is an Exciter Auxiliary I/O Interface Board for GE Speedtronic Mark VI / EX2100 generator excitation system. It acts as the peripheral auxiliary signal conditioning and isolated acquisition unit for the excitation system. The board collects, isolates and conditions analog and digital auxiliary signals including cabinet temperature, status feedback and auxiliary protection triggers, converting external monitoring signals into recognizable signals for the main controller. It supports auxiliary condition monitoring and alarm interlock of the excitation system, with galvanic signal isolation and excellent noise immunity. It is a dedicated spare part for EX2100 excitation cabinets of gas turbine and steam turbine generator sets.
