>>>>>型号:9907-1183 人机界面可配备 NEMA 4X 级保护外壳
【功能描述】
伍德沃德的 9907-1183 人机界面可配备 NEMA 4X 级保护外壳。虽然外壳是可选的，但建议使用，因为它能够有效地保护机电组件免受任何永久性损坏。外壳防水、防尘，适用于恶劣的户外条件。
9907-1183 型号配备 32 位微控制器，可控制各种涡轮机，例如工业尺寸的标准蒸汽轮机、公用涡轮发电机和涡轮膨胀机型号。 它可以配置为独立设备，也可以与工业工厂的DCS（分布式控制系统）协同运行。505E 控制器设计用于操作大多数汽轮机系统的抽气和/或进气。
这款伍德沃德 HMI 采用 PID 结构，非常适合需要监测和控制涡轮转速、负载、入口压力、排气集管压力或抽气/进气集管压力等参数的应用。通过 4–20 mA 传感器和 PID 以及比率/限制器功能，9907-1183 可精确控制抽气/进气，同时保护涡轮机不超出其参数运行。

【英文介绍】
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.
