9907-164 WOODWARD 程序模块

此处列出的设备是 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。这些控制模块专为操作蒸汽轮机以及涡轮发电机和涡轮膨胀机模块而设计。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，时至今日仍然是市场上领先的工业公司之一。这些 505 和 505E 型号可从我们的 AX Control Inc. 获得，作为我们二手但翻新和维修数字硬件库存的一部分。

9907-164边缘控制器设备利用了新的IT 通信和物联网的技术，同时保留了PLC/PAC 在OT方面的 边缘控制器的通信有两个不同层面：一个是采集工业设备和过程数据的I/O，以及与其它工业控制设备通信，属于OT范畴；另一个是边缘设备与OT数据中心及云端服务器之间的通信，属于IT的范畴，也即属于工业互联网的范畴。作为IT和OT之间的一个物理接口，在完成工作站或生产线的控制功能基础上，提升工业设备的接口能力和计算能力，提高工业设备的适用性，所以在一定程度上能够促进IT与OT的融合。因此，边缘控制器多种技术的组合能够满足多种应用需求，因而非常适合工业应用。与传统PLC不同，边缘控制器能够提供连接解决方案，包括充当OPC或消息队列遥测传输（MQTT）服务器。

9907-164 装置设计用于通过操作汽轮机的单次抽汽和/或汽轮机来控制汽轮机。它利用涡轮机的分离级执行器(其中一个或两个)来驱动蒸汽入口阀。

该单元与任何 505 调速器模块一样，可以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 配备了一系列离散和模拟输入：16 个触点输入(其中 4 个是专用的，其中 12 个是可编程的)，然后是 6 个可编程电流输入，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、阀位限制器、自动启动顺序和停机先出指示器。

The devices listed here are models 9907-164 and are part of the 505 and 505E governor control units based on microprocessors. These control modules are designed for the operation of steam turbines as well as turbogenerator and turboexpander modules. The 505/505E series was originally developed, produced and manufactured by the Woodward Company. Woodward is America’s oldest industrial manufacturer, founded in 1870, and remains one of the leading industrial companies in the market today. These 505 and 505E models are available from our AX Control Inc. Acquired as part of our used but refurbished and repaired digital hardware inventory.

9907-164 Edge controller equipment uses new IT communication and Internet of Things technology, while retaining PLC/PAC in OT edge controller communication has two different levels: one is the acquisition of industrial equipment and process data I/O, and communication with other industrial control equipment, belongs to the OT category; The other is the communication between edge devices and OT data centers and cloud servers, which belongs to the category of IT, that is, the category of industrial Internet. As a physical interface between IT and OT, on the basis of completing the control functions of workstations or production lines, the interface capability and computing power of industrial equipment are improved, and the applicability of industrial equipment is improved. Therefore, the integration of IT and OT can be promoted to a certain extent. Therefore, the combination of edge controller technologies can meet a variety of application needs, so it is very suitable for industrial applications. Unlike traditional PLCS, edge controllers are able to provide connectivity solutions, including acting as OPC or message queue telemetry Transfer (MQTT) servers.

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

The unit, like any 505 governor module, 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 (four of which are dedicated, 12 of which are programmable), followed by six programmable current inputs ranging from 4 to 20 mA. Standard features included in the 9907-164 feature include critical speed avoidance, valve position limiter, automatic start sequence, and stop-first out indicator.
