Models 9907-1183 are equipped with a 32-bit microcontroller that allows control of a wide variety of turbines, such as industrial-scale standard steam turbines, utility turbine generators, and turbine expansion models. It can be configured as a standalone device, or it can work in conjunction with a distributed control system in the plant. The 505E controller is designed to operate the extraction and/or admission of most steam turbine systems.
The Woodward HMI has a PID construction that makes it ideal for applications where parameters such as turbine speed, load, inlet pressure, exhaust manifold pressure, or extraction/intake manifold pressure need to be monitored and controlled. The 9907-1183 uses a 4-20mA sensor and PID and ratio/limiter function to precisely control extraction/admission while protecting the turbine from operating outside its parameter range.

Easy maintenance: The digital governor has a user-friendly operation interface and simple appearance design, which is convenient for users to operate and maintain. It also has self-diagnosis and troubleshooting functions, which can help users quickly locate and resolve problems, reducing maintenance costs and downtime.
Energy saving and environmental protection: the digital governor can realize the precise control of the motor and reduce the waste and pollution of electric energy. At the same time, it also has low noise and vibration, and has less impact on the surrounding environment.
In short, the digital governor has the characteristics of high precision, good stability, strong programmability, easy maintenance and energy saving and environmental protection. It is an efficient, reliable and intelligent control equipment, which has been widely used in industrial fields and mechanical equipment.
The role of the digital governor is mainly to control the speed of the DC motor to achieve accurate control of the motor. It changes the speed of the motor by adjusting the voltage and current of the motor. Compared with the traditional voltage type or current type control mode, the digital governor has better control accuracy and dynamic performance. At the same time, it can also realize the joint control of torque and speed, which is widely used in the machinery industry.
In addition, the digital governor also has the control function of setting the starting fuel amount and cutting off the starting air delay after starting, the governor parameter characteristic curve and its control function, the acceleration rate limit function of the speed of the vehicle, the automatic control function of avoiding the critical speed zone, the maximum speed limit function and the function of limiting the maximum oil supply according to the scavenging air pressure.
