IS210WSVOH1AE GE Mark VIe WSVO Servo Valve Output Board
H2: Product Overview
IS210WSVOH1AE is the WSVO Servo Valve Output Board for GE Mark VIe Speedtronic turbine control system. WSVO stands for Servo Valve Output, this board executes closed-loop control for turbine hydraulic servo valves. It outputs precise analog drive signals and reads dual LVDT position feedback to regulate fuel valves, steam stop valves and inlet guide vanes in gas & steam turbines.
It is a critical actuator control component in power plant turbine control cabinets. This GE board has reached end-of-life. We supply original surplus and fully bench-tested refurbished IS210WSVOH1AE units for plant maintenance, emergency spare replacement and DCS retrofit projects. All modules pass complete functional testing before shipment.
