>>>>>型号:9907-164 基于数字微处理器的控制器 适用于带单量程或分体式执行器
【功能描述】
这里列出的设备是 9907-164 型号，是基于微处理器的 505 和 505E 调速器控制单元的一部分。这些控制模块专门设计用于操作汽轮机、涡轮发电机和透平膨胀机模块。505/505E 系列最初由伍德沃德公司开发、生产和制造，伍德沃德是美国历史最悠久的工业制造商，成立于 1870 年，至今仍是市场上领先的工业公司之一。
9907-164 装置设计用于通过操作单次抽气和/或汽轮机进气来控制汽轮机。它利用涡轮机的分级执行器（其中一个或两个）来驱动进气阀以获取蒸汽。
与任何 505 调速器模块一样，该装置可由现场操作员在现场进行配置。菜单驱动的软件由集成在设备正面的操作员控制面板进行控制和更改。该面板显示两行文本，每行 24 个字符。
9907-164 配备一系列分立式和模拟输入：16 个触点输入（其中 4 个专用，12 个可编程），然后是 6 个可编程电流输入，电流为 4 至 20 mA。9907-164 功能中包含的标准功能包括临界速度避让、阀门限制器、自动启动顺序和用于停机的先出指示器。

【英文介绍】
The device listed here is Model 9907-164 and is part of the microprocessor based 505 and 505E governor control units. These control modules are specifically designed to operate steam turbines, turbine-generators and expander modules. The 505/505E series was originally developed, produced and manufactured by the Woodward Company, America's oldest industrial manufacturer, founded in 1870 and still one of the leading industrial companies in the market.
The 9907-164 unit is designed to control the steam turbine by operating a single extraction and/or steam turbine intake. It utilizes the turbine's staged actuators (one or both of them) to drive the intake valve to obtain steam.
As with any 505 governor module, the unit can be configured in the field by a field operator. The menu-driven software is controlled and changed by an operator control panel integrated on the front of the device. The panel displays two lines of text, each of 24 characters.
The 9907-164 is equipped with a range of discrete and analog inputs: 16 contact inputs (of which 4 are dedicated and 12 are programmable), followed by 6 programmable current inputs with currents from 4 to 20 mA. Standard features included in the 9907-164 feature include critical speed avoidance, valve limiter, automatic start sequence, and first-out indicator for shutdown.
