Type 8793 Digital ElectroPneumatic Process Controller SideControl

The robust and compact process controller is designed to standardization 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 electro pneumatic SideControl process controller can be operated by the usual current and voltage standard signals and can also be equipped with the fieldbus interface. 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 Analog feedback all Analog values on the controlling level can be transferred. The parameterization of process controller and positioner can be carried out automatically. The process controller is equipped with additional diagnostic functions to monitor the state of the valve. Through status signals, valve diagnostic messages are transmitted according to NAMUR NE 107 recommendations and recorded as history. With the diagnosis, the operating conditions of the control valve can be monitored. This allows planned maintenance and optimizes plant availability. The easy handling and the selection of additional software functions are done either on a graphic display with backlight. 

For the user, operation is very simple, clear and identical to the Bürkert positioner or process controller TopControl, Type 8692/8693. The pilot valve system can be used equally for single and double acting actuators. It is characterized by a defined safety feature in case of failure of the electrical or power supply and possesses an enormous air capacity range with pressure supply up to 7 bar.
