Woodward unit 9907-164. From 505 digital microprocessor controllers for steam turbines with single or split-range actuators.
Product description
The devices listed here are models 9907-164 and are part of the 505 and 505E microprocessor-based governor control units.
These control modules are specifically designed to operate steam turbines, turbogenerators 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.
The 9907-164 unit is designed to control the steam turbine by operating a single extraction and/or admission of steam.
It uses one or both of the turbine's stage actuators to drive the steam inlet valve.
As with any 505 governor module, the unit can be configured in the field by a field operator.
The menu-driven software is controlled and changed by an operator control panel integrated on the front of the device. 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 ranging from 4 to 20 mA.
Standard features on the 9907-164 include critical speed avoidance, valve limiter, automatic start sequence, and stop-first out indicators.
When starting an engine, turbine, or other type of prime mover, be prepared for an emergency stop to prevent loss of control or excessive speed resulting in personal injury.
