SAMSON 3730-4 technology data
The 3730-4 positioner is a smart, bus-powered field unit conforming to PROFIBUS-PA specification based on IEC 61158-2 transmission technology. The microprocessor-controlled positioner compares the reference variable cyclically transmitted over the PROFIBUS-PA net- work to the travel or opening angle of the control valve and pro- duces the corresponding output signal pressure. The Type 3730-4 Positioner communicates using PROFIBUS-PA specification according to IEC 61158 and IEC 61784 to ex- change data with programmable logic controllers, automation systems and various engineering tools.
