9907-165

About the 9907-165

This unit is a part of the 505 and 505E series of microprocessor-based control systems. This series was developed and produced by Woodward Inc., the world’s oldest and largest independent manufacturing company for aircraft and industrial engines and turbines. The 505/505E line consists of control modules designed for the operation of steam turbines. These units achieve this by utilizing one or two of the split-stage actuators to drive the inlet steam valves. The 505/505E series is built for single extraction and admission for steam turbines. The digital controls in this series are completely programmable to the user’s specifications. They utilize menu-focused software to allow on-site engineers to program the control of a specific generator or electromechanical drive.

This unit is designated as the 9907-165 model of the Woodward Inc. 505E microprocessors. It is able to be configured as a stand-alone device or can operate in tandem with an industrial plant’s DCS, distributed control system.

The 9907-165 model is equipped with 32-bit microcontroller capabilities in order to control a wide variety of turbines, such as industrial-sized standard steam turbines, smaller, utility turbogenerators, and turboexpander models.

This unit’s operational conditions include a set of standard ranges, such as the ambient temperature range of negative 25 to 65 degrees Celsius. The unit is outfitted with a NEMA Type 4 enclosure, though it is optional. The casing brings the acceptable temperature range to negative 25 to 55 degrees C.
