Product Performance
High precision control: using digital PID algorithm and adaptive control technology to achieve precise adjustment of speed and load, with fast dynamic response and strong anti-interference ability.
Redundancy design: Supports dual machine hot standby redundancy configuration (with redundant modules), ensuring seamless switching in case of system failure and improving reliability.
Flexible configuration: Parameter programming can be performed through Woodward ProAct software, supporting custom control logic, limit settings, and alarm thresholds.
Fault diagnosis: Built in self diagnostic function, real-time monitoring of sensor, actuator, and internal circuit status, supporting fault code storage and remote reading.
Compatibility: Seamless integration with Woodward actuators (such as electro-hydraulic actuators, electronic throttle valves) and third-party devices (such as PLC, DCS).
