Description
Woodward 8200-226 Servo Position Controller (SPC)
1. Product Description
The Woodward 8200-226 is a high-precision servo position controller (SPC) designed to drive hydraulic or pneumatic servo valves in industrial applications. As the latest iteration in Woodward’s SPC series, it replaces older models like the 8200-224 and 8200-225, offering enhanced performance and compatibility. The 8200-226 accepts position commands via DeviceNet communication or 4–20 mA analog signals, enabling seamless integration with control systems. Its dual-channel architecture supports redundant feedback from AC/DC devices, ensuring reliable operation in critical environments. With Windows-based configuration software and advanced features like position loop filtering, the 8200-226 optimizes actuator positioning for turbines, compressors, and other machinery requiring precise motion control.
