Product Description
Product: Woodward 8200-226 – SPC Servo Position Controller
Woodward 8200-226 | High Precision Digital Valve Actuator Driver for Turbine & Engine Control System
Woodward 8200-226 is a digital Servo Position Controller (SPC) from Woodward, upgraded replacement model for legacy 8200-224 and 8200-225 units. It acts as the signal conversion and closed-loop drive core between turbine main control systems and hydraulic/pneumatic servo actuators. The module receives position setpoint signals via analog 4–20mA or DeviceNet bus, collects real-time position feedback from LVDT/RVDT/potentiometer sensors, runs high-speed PID closed-loop algorithms, and outputs bipolar proportional current to drive fuel valves, steam control valves and gas throttle actuators. Widely deployed on gas turbines, steam turbines, reciprocating engines and generator sets to maintain stable speed, load and combustion ratio control.
