Produkteinführung
The Woodward 9907-023 is a reliable and field-proven Direct Acting Speed Control Module engineered to regulate engine or turbine speed in industrial and prime power applications. Specifically designed for use with Woodward’s actuators, this control module delivers consistent speed regulation without the need for complex programming or high-level automation interfaces.
As part von Woodward’s EGC (Electronic Governor Control) family, the 9907-023 operates in direct-acting mode, meaning it uses the speed signal to control the actuator directly with minimal signal processing latency. This makes it ideal for medium- to high-speed engines, especially where simplicity, fast response, and reliability are essential.
Suitable for both droop and isochronous control modes, the 9907-023 is commonly found in generator sets, marine propulsion systems, compressors, and other industrial applications that require dependable speed stability across load ranges.
