Woodward 9907-1290 ProAct Model II Digital Speed Controller

The Woodward 9907-1290 ProAct Model II is a digital governor controller designed to manage engine speed and actuator positioning in demanding industrial environments.

The controller receives speed feedback signals from magnetic pickups or speed sensors, processes operating conditions through its digital control system, and adjusts actuator output to maintain accurate engine speed. It is commonly integrated with diesel and gas engines used in generator sets, mechanical drive systems, and turbine applications.

Compared with traditional analog governors, the ProAct Model II provides improved adjustment flexibility, faster response, and enhanced control stability. The unit supports modern automation requirements and can be integrated into larger control systems through communication and diagnostic functions.
