【功能描述】
這里列出的設(shè)備是 9907-164 型號，是基于微處理器的 505 和 505E 調(diào)速器控制單元的一部分。這些控制模塊專門設(shè)計(jì)用于操作汽輪機(jī)、渦輪發(fā)電機(jī)和透平膨脹機(jī)模塊。505/505E 系列最初由伍德沃德公司開發(fā)、生產(chǎn)和制造，伍德沃德是美國歷史最悠久的工業(yè)制造商，成立于 1870 年，至今仍是市場上領(lǐng)先的工業(yè)公司之一。
9907-164 裝置設(shè)計(jì)用于通過操作單次抽氣和/或汽輪機(jī)進(jìn)氣來控制汽輪機(jī)。它利用渦輪機(jī)的分級執(zhí)行器（其中一個或兩個）來驅(qū)動進(jìn)氣閥以獲取蒸汽。
與任何 505 調(diào)速器模塊一樣，該裝置可由現(xiàn)場操作員在現(xiàn)場進(jìn)行配置。菜單驅(qū)動的軟件由集成在設(shè)備正面的操作員控制面板進(jìn)行控制和更改。該面板顯示兩行文本，每行 24 個字符。
9907-164 配備一系列分立式和模擬輸入：16 個觸點(diǎn)輸入（其中 4 個專用，12 個可編程），然后是 6 個可編程電流輸入，電流為 4 至 20 mA。9907-164 功能中包含的標(biāo)準(zhǔn)功能包括臨界速度避讓、閥門限制器、自動啟動順序和用于停機(jī)的先出指示器。

【英文介紹】
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.
