Introduction to the FOXBORO positioner SRD991 series

The Intelligent Positioner SRD991 is designed to operate pneumatic valve actuators and can be operated from a control system (e.g., Foxboro I/A Series System), controller, or PC-based configuration and operation tool (e.g., FDT / DTM VALcare or Valve Monitor). The positioner can be used with different communication protocols. The multilingual full-text graphic LCD as well as the 3 buttons allow easy and comfortable local configuration and operation. For installations in contact with explosive atmospheres, certificates are available.
