Woodward 9907-164 Digital Microprocessor Controller

Woodward Unit 9907-164. from 505 Digital Microprocessor Controller for Steam Turbines with Single or Split Range Actuators.

Product Description.

The unit listed here is model 9907-164 and is part of the 505 and 505E microprocessor based governor control units.

These control modules are specifically designed to operate steam turbines, turbine generators and turbo-expander modules.

The 505/505E series was originally developed, produced and manufactured by Woodward.

Woodward is the oldest industrial manufacturer in the United States, founded in 1870. and remains one of the leading industrial companies in the marketplace.

The 9907-164 unit is designed to control a steam turbine by operating a single extraction and/or intake of steam from the turbine.

It utilises the turbine's staged actuators (either one or both) to actuate 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 into the front of the unit. The panel displays two lines of text with 24 characters per line.

The 9907-164 is equipped with a range of discrete and analogue inputs:16 contact inputs (of which 4 are dedicated and 12 programmable) followed by 6 programmable current inputs, 4 to 20 mA.

Standard features of the 9907-164 include critical speed avoidance, valve limiter, automatic start sequence, and shutdown first-out indicator.

Prepare for an emergency stop when starting an engine, turbine, or other type of prime mover to prevent personal injury from loss of control or overspeed.
