该单元是505和505E系列基于微处理器的控制系统的一部分。该系列由伍德沃德公司开发和生产，伍德沃德公司是世界上历史悠久，规模大的飞机和工业发动机和涡轮机独立制造公司。505/505E线由控制模块组成，设计用于汽轮机的操作。这些装置通过利用一个或两个分级执行器来驱动进口蒸汽阀来实现这一目标。505/505E系列是为蒸汽轮机的单一提取和入场而建造的。在这个系列的数字控制是完全可编程的用户的规格。他们利用以菜单为中心的软件，允许现场工程师对特定发电机或机电驱动器进行编程控制。
该机组的运行条件包括一套标准范围，例如环境温度范围为- 25至65摄氏度。该设备配备了NEMA 4型外壳，尽管它是可选的。套管的可接受温度范围为- 25至55摄氏度。
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.
