9907-164 数字微处理器 配备一系列离散和模拟输入

【产品详情】

伍德沃德单元 9907-164 来自 505 基于数字微处理器的控制器，用于带单量程或分量程执行器的蒸汽轮机。

此处列出的设备是 9907-164 型号，是基于 505 和 505E 微处理器的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蒸汽轮机以及涡轮发电机和透平膨胀机模块。伍德沃德是美国最古老的工业制造商，成立于505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个抽气和/或进入涡轮机来控制蒸汽轮机。它利用涡轮机的分式执行器（其中一个或两个）来驱动蒸汽入口阀。

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 配备一系列离散和模拟输入：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回避、气门限制器、自动启动顺序和停机先出指示器。

【英文介绍】

The Woodward unit 9907-164 is derived from 505 digital microprocessor-based controllers for steam turbines with single or split range actuators.

The device listed here is model 9907-164 and is part of the governor control unit based on the 505 and 505E microprocessors. These control modules are specifically designed to operate steam turbines as well as turbine-generator and turboexpander modules. Woodward is America's oldest industrial manufacturer, founded in 505, and remains one of the leading industrial companies in the market today. These 505 and 1870E models are available from AX Control Inc. Acquired as part of our inventory of used, but refurbished and repaired digital hardware.

The 9907-164 unit is designed to control a steam turbine by operating a single extraction and/or entry turbine. It uses one or both of the turbine's split actuators to drive the steam inlet valve.

As with any 505 governor module, the unit can be configured in the field by a field operator. 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 stop-first out indicators.
