The Woodward 9907-164 is a part of a governor control unit based on 505 and 505E microprocessors, specifically designed for operating steam turbines, turbine generators, and turbine expander modules. This controller was originally developed, produced, and manufactured by Woodward Inc., which utilizes split actuators (one or two) of the turbine to drive the steam inlet valve and control the steam turbine by operating a single extraction and/or intake of the turbine.

The 9907-164 device is equipped with a series of discrete and analog inputs, including 16 contact inputs (4 of which are dedicated and 12 are programmable), as well as 6 programmable current inputs, with currents ranging from 4 to 20mA. These inputs enable the controller to receive and process signals from various sensors and actuators, thereby achieving precise control of the turbine.

In addition, the 9907-164 also has a series of powerful functions, such as critical speed avoidance, valve limiters, automatic start sequence, and stop first out indicator. At the same time, it also has a self diagnostic function, which can detect turbine faults and provide alarms, thereby improving the reliability of the system. In addition, the module also has security features to ensure the safety of operations.

The Woodward 9907-164 controller has a wide range of applications, not only for controlling and adjusting generator sets, monitoring and adjusting parameters such as voltage, frequency, and power factor to ensure stable power output, but also for monitoring and controlling various industrial processes, such as temperature, pressure, flow, etc., receiving sensor signals and feedback control based on preset settings. At the same time, it can also implement fault detection and protection strategies, monitor abnormal situations in the system, and trigger corresponding protection actions.

Overall, the Woodward 9907-164 is a powerful and stable governor control unit suitable for various complex industrial applications. Whether in power generation, industrial automation, or other fields, it can provide efficient and reliable solutions to meet various control needs.
