GE IS200VSVOH1B: VME Servo Control Board

1. Core Function and Positioning

2. Key Specifications from Product Documentation

3. Functional Role

• Servo Valve Control: Directly controls 4 electro-hydraulic servo valves, translating control signals from the Mark VI system into precise mechanical movement of fuel or steam valves, critical for regulating turbine speed and power output.
• Feedback Integration: Utilizes LVDT excitation and position feedback to monitor valve positions in real time, enabling closed-loop control to maintain setpoints and correct deviations.
• Redundancy Support: Compatible with TMR systems, ensuring reliable operation in mission-critical applications by providing fault tolerance and system continuity.

4. Application Scenarios

• Gas/Steam Turbines: Deployed in power plants, refineries, and industrial facilities to control fuel and steam flow via servo-actuated valves, optimizing turbine efficiency and safety.
• Turbine Load Management: Adjusts fuel/steam input dynamically in response to load demands, ensuring stable turbine operation across varying conditions.
