IS210WSVOH1AE IS200WSVOH1ADD

IS210WSVOH1AE is a 2-channel Servo Valve Control Module (WSVO) for GE Speedtronic Mark VIe gas/steam turbine control systems, enabling electro-hydraulic servo valve drive and closed-loop position control. It delivers 4–20 mA servo outputs to actuate fuel valves, IGV guide vanes, and extraction valves; supports LVDT/RVDT position feedback with ±0.1% FS accuracy and ≤500 Ω load per channel. Featuring a special assembly version and Class A functional revision, it enhances system stability and reliability. Compatible with simplex/redundant configurations, it is ideal for power and oil & gas turbine control to ensure precise, stable, and safe operation.1.
