Description
The digital process controller type 8793 is designed for mounting on thrust and swivel drives with standardization in accordance with IEC 60534-6-1 and/or VDI/VDE 3845 (IEC 60534-6-2). The variant with remote position sensor can also be used to control Bürkert process control valves. The process controller processes all common current and voltage standard signals and can be equipped optionally with a fieldbus interface. The actual value of the process variable is fed directly to the device as a 4 - 20 mA, Pt 100 or frequency signal. The process controller calculates the internal setpoint for the lower-level positioner from the target-actual comparison. The process and position controller can be parameterized automatically by means of the Tune function. The device is easy to use via the graphic display with buttons or via Bürkert Communicator.
The process controller is equipped with diagnostic functions for valve monitoring. With the diagnostics, the operating conditions of the control valve can be monitored, WAS makes the maintenance decisions predictable, if necessary, and the availability of the systems optimized.
The pneumatic actuator system can be used equally for single and double-acting drives. It is characterized by a defined safety behavior in the event of failure of the electrical or pneumatic auxiliary power and has a very large usable air power range with supply pressures up to 7bar.
