Product Overview (English)
Woodward 8200-226 Servo Position Controller Module is specifically designed for industrial closed-loop control applications. It can process both DeviceNet bus signals and 4-20mA analog inputs, achieving micrometer-level positioning accuracy. This module adopts digital signal processing technology to precisely control proportional servo valves and integral servo valves, widely used in metallurgical machinery, chemical equipment, and automated production lines.
As a key component of Woodward’s digital control solution, the 8200-226 module integrates dual redundancy design with hot-swapping capability. Its core advantages include 24Vdc power system compatible with multiple industrial standards, support for PROFIBUS-DP and Modbus RTU multi-protocol communication, built-in self-diagnosis function for real-time valve position feedback monitoring, and IP54-rated industrial-grade metal housing. These features make it particularly suitable for long-term stable operation in harsh environments such as high temperature, dust, and vibration.
