About 9907-164
The devices listed here are models 9907-164 and are part of the 505 and 505E governor control units based on microprocessors. These control modules are designed for the operation of steam turbines as well as turbogenerator and turboexpander modules. The 505/505E series was originally developed, produced and manufactured by the Woodward Company. Woodward is America’s oldest industrial manufacturer, founded in 1870, and remains one of the leading industrial companies in the market today. These 505 and 505E models are available from AX Control Inc. As part of our inventory of used, refurbished and repaired digital hardware.
trait
With accurate control performance, real-time monitoring and adjustment of speed;
With a variety of control functions, including speed control, load control, etc.
Equipped with a variety of input and output interfaces, can be integrated with other control systems;
Supports communication interfaces to enable data exchange with other devices or systems.
The 9907-164 is part of the 505 and 505E microprocessor control units. These control modules are specifically designed to operate steam turbines, as well as turbine generator and turbine expander modules.
Unit 9907-164 is designed to control steam turbines by operating a single extraction and/or entry turbine. It utilizes the turbine’s phased drive, either or both, to drive steam from the inlet valves.
This unit, like any of the 505 Governor modules, can be configured in the field by a field operator. Menu-driven software is controlled and modified by the operator control panel integrated into the front of the unit. The panel displays two lines of text, each of 24 characters.
The 9907-164 is equipped with a range of discrete and analog inputs :16 contact inputs (of which 4 are dedicated and 12 are programmable), followed by 6 programmable current inputs (4-20mA). Standard features in the 9907-164 feature include: critical speed evasion, valve limiter, automatic start sequence and close first-out indicator.
