该装置是伍德沃德公司控制装置系列中的几个装置之一。这些装置被设计成一系列数字控制模块。它们被构建为能够在现场进行配置，配置为控制特定的应用，并且能够在未来改变这种情况。这些装置是灵活的，主要用于汽轮机控制，但也能控制公用事业涡轮发电机和涡轮膨胀机模型。

该装置被列为9907-170，一个标准的伍德沃德505E微处理器为基础的控制装置。它使用一个或两个分阶段致动器来运行入口蒸汽阀，从而操作汽轮机。9907-170能够操作汽轮机的单一抽汽和进汽。

505E系列配备了基于菜单的软件，能够指导现场工程师对特定发电机或驱动应用进行编程控制。

实际上，9907-170配备了一个32位微处理器单元来处理控制功能，然后是一系列印刷电路板。在外部，有一个安装设置附件，可以安装在系统网络面板内。另一个外部特征是嵌入前面板的操作员控制面板。该控制面板显示两行文本，每行24个字符。该面板用于配置9907-170装置的操作规范。

9907-170

This device is one of several devices in the Woodward control device series. These devices are designed as a series of digital control modules. They are built to be configured on-site, configured to control specific applications, and able to change this situation in the future. These devices are flexible and mainly used for turbine control, but can also control utility turbine generators and turbine expander models.

This device is listed as 9907-170, a standard Woodward 505E microprocessor based control device. It uses one or two staged actuators to operate the inlet steam valve, thereby operating the turbine. 9907-170 is capable of operating a single extraction and inlet of the steam turbine.

The 505E series is equipped with menu based software that can guide on-site engineers in programming and controlling specific generator or drive applications.

In fact, the 9907-170 is equipped with a 32-bit microprocessor unit to handle control functions, followed by a series of printed circuit boards. Externally, there is an installation setting attachment that can be installed inside the system network panel. Another external feature is the operator control panel embedded in the front panel. This control panel displays two lines of text, each containing 24 characters. This panel is used to configure the operating specifications for the 9907-170 device.
