Product Description

The 9907-135 is a high-precision actuator driver module developed by Woodward, Inc. for interfacing electronic control systems with mechanical actuators in turbine and engine applications.

It converts low-level control signals into high-power drive outputs required for accurate valve and linkage positioning. The module is commonly used in fuel metering and prime mover governing systems, providing fast response times, low hysteresis, and stable closed-loop control performance.

Its compact, ruggedized design allows installation in space-limited control cabinets while maintaining strong electrical isolation and resistance to vibration, humidity, and EMI interference.
