About the 9907-1183

Woodward's 9907-1183 Human-Machine Interface can be outfitted with a NEMA 4X grade protective casing. While the casing is optional, it is recommended as it is able to protect the electromechanical components effectively from any permanent damage. The case is watertight, dust-tight, and suitable for harsh outdoor conditions.

The 9907-1183 model is equipped with a 32-bit microcontroller that allows the control of a wide variety of turbines, such as industrial-sized standard steam turbines, utility turbogenerators, and turboexpander models. It is able to be configured as a stand-alone device or can operate in tandem with an industrial plant’s DCS, distributed control system. The 505E controller is designed to operate extraction and/or admission of most steam turbine systems.

This Woodward HMI has a PID structure which makes it ideal for applications where it is required to monitor and control parameters like turbine speed, load, inlet pressure, exhaust header pressure, or extraction/admission header pressure. Via a 4–20 mA transducer and PID,  and ratio/limiter function, the 9907-1183 accurately controls extraction/admission, while protecting the turbine from operating outside its parameters.
