Pneumatic Valve Actuators Intelligent Positioner SRD998 SRD991 SRD960

Foxboro Eckardt Intelligent Positioner SRD998 SRD991 SRD960 For Pneumatic Valve Actuators With Hart - Dp Flow

The intelligent positioner SRD991 is designed to operate pneumatic valve actuators and can be operated from control systems (e.g. the Foxboro I/A Series System), controllers or PC-based configuration- and operational tools such as PC20 / IFDC or PC50 (FDT Software). The positioner is available with different communication protocols. The multi-lingual full text graphical-LCD in connection with the 3 push buttons allows a comfortable and easy local configuration and operation as well as the display of valve specific data, and status- and diagnostic messages.
