:The robust and compact process controller is designed to standardisation acc. to IEC 60534- 6-1 or VDI/VDE 3845 (IEC 60534-6-2) for assembly with linear and rotary actuators. In addition, the remote version can be combined with Bürkert process control valves. The digital electropneumatic SideControl process controller can be operated by the usual current and voltage standard signals and can also be equipped with the fi eldbus interface PROFIBUS DPV1. The actual process value is directly supplied to the device as 4-20 mA, PT100 or as frequency signal. The process controller calculates the position setpoint for the subordinated positioner through the variance comparison. Due to the analogue feedback all analogue values on the controlling level can be transferred. The parameterization of process controller and positioner can be carried out automatically.
