Functional Design and Turbine Control

The GE IS200TTURH1CFD connects directly to the VME backplane of the cabinet. It reads speed and temperature inputs from field sensors. Then, this board calculates valve position commands for actuators. Onboard non-volatile memory stores tuning parameters permanently. Therefore, the IS200TTURH1C maintains stable turbine operation across all load conditions.

Installation and Compatibility Notes

You must upload the application firmware before installing this control board. The GE IS200TTURH1C fits exclusively into Mark VI series cabinets. Always replace faulty units with identical GE board revisions. Additionally, verify the configuration file matches your turbine type. This practice ensures proper control response during startup and shutdown.
