Woodward 9907-164 Governor Control Unit

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 control module controls the steam turbine by operating a single extraction and/or intake of the turbine, using the turbine’s split actuators (one or two) to drive the steam inlet valve.

Like any 505 governor module, the WOODWARD 9907-164 device can be configured by on-site operators on site. The menu driven software is controlled and modified by an operator control panel integrated on the front of the device, which can display two lines of text with 24 characters per line. In addition, it is equipped with a series of discrete and analog inputs, including 16 contact inputs (including 4 dedicated and 12 programmable), as well as 6 programmable current inputs (current ranging from 4 to 20 mA).

The function of this device is very comprehensive, including standard functions such as critical speed avoidance, valve limiters, automatic start sequence, and stop first out indicator. These functions help ensure the safety and stability of the equipment during startup and operation, and prevent personal injury caused by loss of control or overspeed.

Overall, WOODWARD 9907-164 is a powerful and flexible control module suitable for industrial automation applications that require precise control of steam turbines, turbine generators, and turbine expander modules. It can help users improve production efficiency, reduce maintenance costs, and ensure the safe and stable operation of the process flow.

Please note that when selecting and using this control module, it is necessary to configure and debug it according to specific application scenarios and requirements to ensure its optimal performance and effectiveness. At the same time, it is also necessary to comply with relevant safety regulations and operating guidelines to ensure the safe and stable operation of the equipment.
