GE IS200TSVCH1A IS200TSVCH1AEC Servo Board

The GE IS200TSVCH1A and GE IS200TSVCH1AEC function as precision servo terminal boards for turbine control systems. These modules belong to the Mark VI series from General Electric. They directly interface with servo valves for fuel and steam control. Consequently, these boards enable precise positioning of critical turbine actuators.

Functional Design and Servo Control

The GE IS200TSVCH1AEC connects directly to the analog output backplane. It receives position commands from the main turbine controller. Then, this board converts these commands into current signals for servo valves. Each channel includes a dedicated power amplifier for high drive capability. Therefore, the IS200TSVCH1A provides smooth and accurate valve positioning.

Installation and Compatibility Notes

You must verify servo coil resistance before connecting to this terminal board. The GE IS200TSVCH1A fits exclusively into Mark VI series turbine cabinets. Always replace faulty units with identical GE board revisions. Additionally, calibrate each channel using the onboard potentiometers. This practice ensures proper valve response across the entire operating range.
