Woodward 9907-164 数字微处理器的控制器

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。这些 505 和 1870E 型号可从 AX Control Inc. 获得，作为我们二手、但经过翻新和维修的数字硬件库存的一部分。

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。

The devices listed here are models 9907-164, which are part of the governor control unit based on 505 and 505E microprocessors. These control modules are specifically designed for operating steam turbines as well as turbine generator and turbine expander modules. Woodward is the oldest industrial manufacturer in the United States, founded in 505 and still one of the leading industrial companies in the market. These 505 and 1870E models are available from AX Control Inc. as part of our used but refurbished and repaired digital hardware inventory.

The 9907-164 device is designed to control the steam turbine by operating a single extraction and/or entering the turbine. It utilizes the fractional actuators of the turbine (one or two of them) to drive the steam inlet valve.

Like any 505 governor module, this device can be configured by on-site operators on site. The menu driven software is controlled and modified by an operator control panel integrated on the front of the device. This panel displays two lines of text, each containing 24 characters.

The 9907-164 is equipped with a series of discrete and analog inputs: 16 contact inputs (including 4 dedicated and 12 programmable), followed by 6 programmable current inputs, with currents ranging from 4 to 20 mA. The standard functions included in the 9907-164 function include critical speed avoidance, valve limiter, automatic start sequence, and stop first out indicator.
