9907-163 WOODWARD 505 DIGITAL GOVERNOR FOR STEAM TURBINES.

General Description

The 505 9907-163 controller is designed to control single or dual (split range) actuator steam turbines (extraction steam turbines require the 505XT version). The 505 is field programmable which allows a single design to be used in many different control applications and reduces both cost and delivery time. Woodward Governor uses menu-driven software to instruct site engineers on programming the control to a specific generator or mechanical drive application. The 505 can be configured to operate as a stand-alone unit or in conjunction with a plant’s Distributed Control System.

The 505 is a field configurable steam turbine control and operator control panel (OCP) 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. Easy-to-follow instructions are presented in English through the OCP’s two-line display and operators can view actual and setpoint values from the same screen.

9907-163, 505 controllers now utilize a special polyacrylate conformal coating material. So that this Coating protects their internal circuit boards from corrosive environments. This new polyacrylate material replaces the previous silicone conformal coating. This provides an improved barrier between board components and sulfur-based gases. 505 controls that have this coating will have a label on the side stating
“SULFUR RESISTANT CONFORMAL COATED”.
