IS200EXAMG1B New and Original

The GE IS200EXAMG1B is an Exciter Attenuation Module (EXAM) designed for the EX2100 / EX2100e Excitation Control System and Mark VI Speedtronic platform. It serves as the high-voltage front-end interface for the excitation circuit’s ground detection system . The EXAM module solves a critical engineering challenge: the generator excitation circuit operates at lethal voltages (125 VDC to 1000 VDC), while the ground detection logic circuitry operates at low voltages. The IS200EXAMG1B bridges this gap by attenuating high-voltage signals from the excitation rectifier bridge into precise low-level signals that the IS200EGDM Ground Detector Module can safely process .
