The Universal Positioner SRD960 is designed to operate pneumatic valve actuators and is available in the version Ex d (flameproof) / explosion proof.
The positioner is available with different communication protocols. This includes versions with HART-signal, digital with FoxCom protocol, or 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 by using FDT/DTM. 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 DTMs for HART, PROFIBUS 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 comfortably and easily by a backlit multi-lingual full text graphic-LCD in connection with the external 4 push buttons.

SRD991 Intelligent Positioner Ex ia / Intrinsically safe

A wde range of position transmitters is available to monitor position of valves and actuators.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.
