>>>>>型號:9907-1183 人機界面可配備 NEMA 4X 級保護外殼
【功能描述】
伍德沃德的 9907-1183 人機界面可配備 NEMA 4X 級保護外殼。雖然外殼是可選的，但建議使用，因為它能夠有效地保護機電組件免受任何永久性損壞。外殼防水、防塵，適用于惡劣的戶外條件。
9907-1183 型號配備 32 位微控制器，可控制各種渦輪機，例如工業(yè)尺寸的標準蒸汽輪機、公用渦輪發(fā)電機和渦輪膨脹機型號。 它可以配置為獨立設備，也可以與工業(yè)工廠的DCS（分布式控制系統(tǒng)）協(xié)同運行。505E 控制器設計用于操作大多數(shù)汽輪機系統(tǒng)的抽氣和/或進氣。
這款伍德沃德 HMI 采用 PID 結構，非常適合需要監(jiān)測和控制渦輪轉速、負載、入口壓力、排氣集管壓力或抽氣/進氣集管壓力等參數(shù)的應用。通過 4–20 mA 傳感器和 PID 以及比率/限制器功能，9907-1183 可精確控制抽氣/進氣，同時保護渦輪機不超出其參數(shù)運行。

【英文介紹】
Woodward's 907-1183 HMI can be equipped with a NEMA 4X-rated protective housing. Although the housing is optional, it is recommended because it effectively protects the electromechanical components from any permanent damage. The housing is waterproof and dust-proof, suitable for harsh outdoor conditions.
Models 9907-1183 are equipped with 32-bit microcontrollers to control a variety of turbines, such as industrial-size standard steam turbines, utility turbine generators, and turbine expansion models. It can be configured as a standalone device or run in conjunction with a DCS (distributed control system) in an industrial plant. The 505E controller is designed to operate the extraction and/or intake of most steam turbine systems.
The Woodward HMI's PID construction makes it ideal for applications where parameters such as turbine speed, load, inlet pressure, exhaust manifold pressure, or extraction/intake manifold pressure need to be monitored and controlled. With a 4-20 mA sensor and PID and ratio/limiter function, the 9907-1183 provides precise control of extraction/intake while protecting the turbine from operating beyond its parameters.
