Introduction to WOODWARD 9907-163
Product Overview
The WOODWARD 9907-163 is a microprocessor-based digital turbine controller, standing as a pivotal component in the brand’s 505 series for steam turbine regulation. It integrates programmable control logic, multi-parameter processing, and user-friendly configuration features to deliver stable speed and load management for single or split-range actuator-equipped turbines. Widely applied in thermal power generation, industrial process drives, and turbogenerator systems, it ensures consistent steam turbine operation in thermal plants, optimizes mechanical drive performance in manufacturing, and maintains reliable output for backup power units. Its robust NEMA 4-compliant enclosure offers excellent protection against dust and water, making it suitable for harsh industrial environments like power plant control rooms and factory workshops. Seamlessly compatible with WOODWARD Varistroke hydraulic actuators and 505 View configuration software, it supports RS-232/RS-422 communication for easy integration into plant control networks, simplifying monitoring and maintenance.
