GE IS200EXAMG1BAA | Exciter Attenuation Module for EX2100e

Description / Overview

The GE IS200EXAMG1BAA is an Exciter Attenuation Module (EXAM) designed by General Electric (GE) for the EX2100e excitation control system. It plays a vital role in monitoring the exciter bridge and converting high-voltage signals into low-voltage outputs for the Exciter Ground Detector Module (EGDM). This ensures accurate fault detection, diagnostic precision, and overall system protection.

The module is also responsible for field flashing relay control, a key function during generator startup to initiate field current. Moreover, it enhances safety by detecting single-point ground faults in the field winding. Built with industrial durability in mind, the IS200EXAMG1BAA can operate reliably in harsh turbine environments. Its rack-mounted design ensures seamless integration within the GE EX2100e system architecture.
