Woodward 9907-162 505 Digital Governor Turbine Control

Woodward 9907-162 505 Digital Governor Turbine Control

The 9907-162 is microprocessor based controls designed to operate steam turbines of all sizes. It is designed to operate steam turbines using one or two (split-stage) actuators to drive inlet steam valves.

The digital controls are field programmable. They use menu-driven software to instruct site engineers on programming the control to a specific generator or mechanical drive application. The 9907-162 can be configured to operate as a stand-alone unit or in conjunction with a plant's Distributed Control System.

Woodward's 505 digital controls use a 32-Bit Microprocessor to control industrial sized steam turbines, small utility turbogenerators, or turbo expanders.

The 9907-162 package consists of printed circuit boards in an enclosure designed to be mounted within a system control panel. An optional NEMA 4X enclosure is available to allow these controls to be mounted within harsh environments. An Operator Control Panel is provided on the 505's front panel. Easy to follow instructions are presented in English through the OCP's two-line display and operators can view actual and set point values from the same screen. Removable terminal blocks allow for easy wiring and installation.

The 9907-162 is a field configurable steam turbine control and operator control panel integrated into one package. A comprehensive operator control panel, including a two-line (24 characters each) display, and a set of 30 keys is located on the 505's front panel. This OCP is used to configure the 505, make On-Line program adjustments, and operate the turbine/system. 

The 9907-162 also performs as a first-out indicator for system shutdowns, thus reducing troubleshooting time. Multiple system shutdowns (3) can be brought into the 505 to allow it to shut down the system safely, and latch-in the cause of the shutdown.
