Tipo 8793 - SideCONTROL digital electropneumatic process controller
Descripción de tipo
The Type 8793 digital process controller is designed with standardisation in accordance with IEC 60534-6-1 or VDI/VDE 3845 (IEC 60534-6-2) for assembly to linear and quarter-turn actuators. The variant with remote position sensor can also be used for closed-loop control of 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 value of the process variable is supplied directly to the device as 4...20 mA, Pt 100 or as a frequency signal. The process controller calculates the position set-point value for the subordinated positioner via variance comparison. The parametrisation of process and position controllers can be carried out automatically via the P.TUNE and X.TUNE functions. 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 at pressure supplies up to 7 bar.
