Original Foxboro Eckardt smart positioner series SRD991 SRD991-BDNS7EA4NY-V10
Intelligent Valve Positioner SRD991 with HART, FoxCom, PROFIBUS-PA, FOUNDATION Fieldbus H1 or Without Communication
The Intellegent Valve 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 operation tools such as the DTMs VALcare
or Valve Monitor. The positioner is available with different communication protocols. The multi-lingual full text graphical-LCD (optional with infrared interface), in conjunction with the 3 push buttons, allows a comfortable and easy local configuration and operation. For installations in contact with explosive atmospheres, certificates are available.
