The intelligent Positioner SRD991 is designed to operate pneumatic valve actuators and is available in the version EEx ia / intrinsically safe.
The positioner is available with different communication protocols. This includes versions with analog setpoint (4 to 20 mA) without communication and with superimposed HART-signal; digital with fieldbus communication according to PROFIBUS-PA and FOUNDATION Fieldbus H1 based on IEC 1158-2 acc. to the FISCO-Model.
The unit can be configured and operated from the Foxboro I/A Series System in connection with our Intelligent Field Device Configurator (IFDC) or the PC-based configuration- and operation tool PC20. The SRD can also be integrated into system environments and applications that support the FDT/DTM concept according to the Specification 1.2.
For this purpose the required Vendor's specific DTMs (called VALcare or Valve Monitor) for HART, PROFIBUS, FOUNDATION Fieldbus and FoxCom are available.
In addition the device can be integrated into any other common control system such as Fisher Rosemount-AMS or -Delta-V, Siemens SIMATIC- PDM, Yokogawa, Honeywell, ABB and SMAR.
The local operation and configuration can be achieved comfortable and easy by a multi-lingual full text graphic LCD in connection with the three push buttons.
