【功能描述】
9907-167 裝置是伍德沃德 505E 系列數(shù)字控制設(shè)備的一部分。這些設(shè)備是伍德沃德公司制造的 505E 系列的一部分。 這是美國歷史最悠久的渦輪控制系統(tǒng)獨立制造商之一。505E 系列專為工業(yè)級汽輪機、小型機組渦輪發(fā)電機或公用事業(yè)透平膨脹機型號等設(shè)備而設(shè)計。505E系列專為蒸汽輪機的單次抽氣和/或進氣而設(shè)計。它通過使用一對執(zhí)行器來驅(qū)動入口蒸汽閥，使汽輪機運行。
該裝置以 9907-167 的數(shù)字名稱列出。 它配備了一個 32 位微處理器，用于控制渦輪機。9907-167 單元的物理主體由一系列印刷電路板單元組成，這些單元安裝在一個能夠牢固地安裝在控制面板系統(tǒng)中的外殼中。
9907-167 型號可配備 NEMA 4X 級保護外殼。該外殼是可選的，但是，它能夠有效地保護機電組件免受任何永久性損壞或任何侵入性顆粒的影響。外殼既防水又防塵，適用于室內(nèi)和室外條件。9907-167 裝置的環(huán)境溫度范圍（不含保護框架）為 -25 至 65 °C，但連接框架后，它只能承受高達 55 °C。

【英文介紹】
The 9907-167 unit is part of the Woodward 505E series of digital control devices. These devices are part of the 505E series manufactured by Woodward. It is one of the oldest independent manufacturers of turbine control systems in the United States. The 505E series is designed for industrial steam turbines, small turbine generators or utility turbine expansion models. The 505E series is designed for single extraction and/or intake of steam turbines. It operates the steam turbine by using a pair of actuators to drive the inlet steam valve.
The device is listed under the numerical names 9907-167. It is equipped with a 32-bit microprocessor for controlling the turbine. The physical body of the unit 9907-167 consists of a series of printed circuit board units that are housed in a housing capable of being securely installed in the control panel system.
Models 9907-167 can be equipped with NEMA Class 4X protective housing. The housing is optional, however, it is effective in protecting the electromechanical components from any permanent damage or any intrusive particles. The housing is both water and dust resistant and suitable for indoor and outdoor conditions. The ambient temperature range of the 9907-167 device (without the protective frame) is -25 to 65 °C, but when the frame is connected, it can only withstand up to 55 °C.
