Overview
The Woodward 8290-185 Isochronous Speed Control module delivers precise engine speed regulation for industrial and power generation systems. Designed for use with Woodward electric actuators, this controller maintains constant speed under varying load conditions, ensuring stable frequency output in critical applications.
Its closed-loop PID algorithm responds rapidly to load changes, minimizing overshoot and maintaining tight speed control. Moreover, the module includes features like start fuel limiting and ramp generation, which improve engine performance during startup and load transitions. In addition, its rugged design and wide operating temperature range make it suitable for harsh environments, including marine and remote installations.
The 8290-185 integrates seamlessly with Woodward actuators such as the 524 and 1724 series. Therefore, it is ideal for upgrading analog governors to digital control in retrofit projects. Whether used in gensets, compressors, or industrial engines, this module offers reliable performance and long-term stability.
