Information About IS200FCGEH1A

The IS200FCGEH1A is a General Electric LCI control and gating-exciter board developed to provide key signal interfacing between the motor field exciter and the LCI drive system. Its primary role is to condition voltage and current feedback signals from the exciter bridge so they can be accurately interpreted by the LCI processor board, ensuring reliable gating control and synchronized inverter operation. Equipped with two 96-pin VMEbus connectors and two 20-pin ribbon cable connectors, the board supports high-speed communication and stable integration within Mark V and LCI architectures. Six analog voltage inputs allow for continuous monitoring of exciter parameters, enabling precise real-time control adjustments critical for heavy-duty industrial systems. Designed with robust components, diagnostic LEDs, and durable construction, the IS200FCGEH1A maintains long-term reliability in turbine control and high-power drive environments.
