Product Description
The device listed here is the 9907-1200 model, a part of the 505 and 505E Microprocessor-based governor control units. These control modules were designed specifically to operate steam turbines, as well as turbogenerators and turboexpander modules. The 505/505E series was developed, produced, and manufactured originally by Woodward Inc. Woodward is the oldest industrial manufacturer in America, founded in 1870, and still, today remains one of the leading industrial companies in the market. These 505 and 505E models are available from us here at AX Control Inc. as a part of our inventory of used, yet reconditioned and repaired digital hardware.

The 9907-1200 unit is designed to control the steam turbine by operating a single extraction and/or the admission for the turbine. It utilizes the turbine’s split-stage actuators, either one or both of them, to drive the inlet valves for steam.

This unit, like any of the 505 governor modules, is able to be configured in the field by the on-site operators. The menu-driven software is controlled and altered by the operator control panel integrated onto the front-facing side of the unit. The panel has a display of two lines of text, 24 characters per line.

The 9907-1200 is outfitted with a series of discrete and analog inputs: 16 contact inputs (4 of them dedicated, 12 of them programmable), and then 6 programmable current inputs, at 4 to 20 mA. The standard features included into the 9907-164’s capabilities are the critical speed avoidance, valve limiters, the auto start sequence, and the first-out indicator for shutdowns.
