Digital electropneumatic Process Controller

Transcription

1 Digital electropneumatic Process Controller Type 879 can be combined with Compact and robust design Easy Start-up using tune function of the Positioner and Process controller Integrated diagnostic functions for valve monitoring (optional) Dynamic positioning system with no air consumption in controlled state Profibus DPV1 or DeviceNet (optional) Yoke type actuators Rotary actuators Rotary actuators with remote positioner Process control valve with remote positioner Hygienic process control valve with remote positioner The robust and compact process controller is designed to standardisation acc. to IEC or VDI/VDE 85 (IEC ) for assembly with linear and rotary actuators. In addition, the remote version can be combined with Bürkert process control valves. The digital electropneumatic process controller can be operated by the usual current and voltage standard signals and can also be equipped with the fieldbus interface PROFIBUS DPV1. The actual process value is directly supplied to the device as -0 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. 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 optimises plant availability. The easy handling and the selection of additional software functions are done either on a graphic display with backlight and keypad or via PC interface. The user operation is very simple and clear, identical to the Bürkert positioner or process controller TopControl, type 869/869. The pilot valve system can be used equally for single and double acting actuators. It is characterised 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.
