9907-167 Woodward Digital Control Unit

Description

The 9907-167 Woodward Digital Control Unit, also known as the Woodward 505 Electronic Governor, is a microprocessor-based speed control system designed for steam turbines and turbomachinery applications. It is engineered to regulate the speed of turbine compressors, industrial steam turbines, small grid turbine generators, or turbine expanders, and can support systems with single or dual actuators. The unit features two core operating modes: programming mode, used to configure internal settings and operational parameters, and run mode, which executes pre-set control logic to manage equipment operation. Its digital control signals are converted to hydraulic signals via an I/H converter, which adjusts the opening of the steam turbine compressor’s main steam valve to maintain precise speed regulation. As part of the Woodward 505 series, this control unit offers flexible, field-configurable functionality, allowing adaptation to specific application requirements and future operational adjustments. It leverages microprocessor technology to deliver reliable, automated speed control for critical turbomachinery systems, ensuring consistent performance across diverse industrial power and compression applications.
