Technical Dossier

Product Details And Specifications

GE IS200 (Mark VI) Series Technical Notes

The GE IS200 series constitutes the core I/O, control, and communication module family of the GE Mark VI Turbine Control System. Deployed across gas turbines, steam turbines, combined-cycle power plants, nuclear auxiliary systems, petrochemical facilities, and offshore platforms, the Mark VI platform represents one of the most widely installed turbine control architectures in global heavy industry. Installations span facilities operated by ExxonMobil, Shell, Saudi Aramco, CNOOC, EDF, and major independent power producers across North America, Europe, the Middle East, and Asia-Pacific. The IS200 module family provides the physical hardware layer for all Mark VI control functions, including analog and digital I/O processing, turbine protection logic, excitation regulation, communication gateway functions, and power distribution. The IS200WEORG1ACD specifically serves as the Excitation Regulator Output board within this architecture, interfacing between the Mark VI controller and the generator excitation system.
