GE IS200WEORG1ACD Exciter Output Relay Board – Mark VI Turbine Control System
When a gas or steam turbine’s exciter output relay board fails, the consequences are immediate and severe: the generator loses voltage regulation, protective relay signals go dark, and the entire turbine-generator unit must be taken offline. In power plants and industrial facilities running GE Mark VI control systems, an unplanned outage caused by a failed I/O board can cost tens of thousands of dollars per hour. The GE IS200WEORG1ACD is the precision-engineered solution that keeps exciter control loops intact and turbine protection circuits fully operational.
The IS200WEORG1ACD occupies a critical position within the Mark VI turbine control architecture — GE’s flagship distributed control platform for gas turbines, steam turbines, and combined-cycle power plants. As the Exciter Output Relay (WEOR) board, it interfaces directly with the excitation system, translating digital control commands from the Mark VI controller into hardwired relay outputs that govern field flashing, exciter protection trips, and voltage regulator enable signals. Deployed globally across GE Frame 5, Frame 6, Frame 7, and Frame 9 turbine installations, this board is a cornerstone of reliable power generation infrastructure.
