Digital electropneumatic Process Controller Side Control
The device Type 8793 digital process controller is designed with standardisation according to IEC 60534-6-1 or VDI/VDE 3845 (IEC 60534-6-2) for assembly to linear and rotary actuators. The variant with remote position sensor can also be used to control Bürkert process control valves. The process controller processes all standard current and voltage signals and can also be equipped with the fieldbus interface. The actual process value is supplied directly to the device as 4-20 mA, PT100 or as a frequency signal. The process controller calculates the position setpoint for the subordinated positioner via variance comparison. The parameterisation of process and position controllers can be carried out automatically via the Tune function. Operation is simple via the graphical display with keypad or via Bürkert Communicator. The process controller is equipped with diagnostic functions to monitor the valve. The diagnostics can be used to monitor the operating conditions of the control valve which makes maintenance decisions predictable and optimises the availability of the plants as required. The pneumatic actuating system can be used equally for single-acting and double-acting actuators. It is characterised by a defined safety response in the event of the failure of the electrical or pneumatic auxiliary power and possesses an enormous air capacity range with pressure supply up to 7 bar.
