9907-164 is an electronic speed regulator product produced by WOODWARD company, which is part of its governor control unit. This product is specifically designed for operating steam turbines, turbine generators, and turbine expander modules, achieving precise speed control by controlling the single extraction or intake of these devices.

In terms of specific functional implementation, 9907-164 utilizes the staged actuators (which can be one or two) of the steam turbine to drive the steam inlet valve, thereby achieving precise control of the steam turbine. It has a series of discrete and analog input interfaces, including 16 contact inputs (4 of which are dedicated and 12 are programmable), as well as 6 programmable current inputs (ranging from 4 to 20 mA).

The standard functions of 9907-164 cover multiple aspects, including critical speed avoidance, valve limiters, automatic start sequence, and stop first out indicator, all of which are aimed at ensuring stable operation and operational safety of the equipment. On site operators can configure and make changes through the operator control panel on the front of the equipment, which uses menu driven software and can display two lines of text, each containing 24 characters.

In addition, the 9907-164 also has a high degree of flexibility and can adapt to various industrial application scenarios. It supports on-site configuration and can be integrated with other control systems to achieve higher levels of automation and intelligent control.

In summary, WOODWARD 9907-164 is a comprehensive and high-performance governor product suitable for various industrial automation applications that require precise control of steam turbines, turbine generators, and turbine expander modules. It can provide effective solutions for improving production efficiency and ensuring equipment operation safety.
