Digital electro-pneumatic process controller SideControl (317941)

The robust and compact process controller is designed for installation on shear and rotary motion drives with standardization according to IEC 534-6 or VDI/VDE 3845. The step-by-step displacement sensor option can also be used to adjust the Burkert process control valves. The digital electro-pneumatic process controller SideControl processes all well-known standard current and voltage signals and, as an option, can be equipped with a PROFIBUS DPV1 or DeviceNet bus AS interface. The actual value of the process parameter is supplied directly to the device as a 4-20 mA, Pt 100 or frequency signal. After comparing the setpoint and the actual values, the process controller calculates the setpoint internal value for the auxiliary sensor of the actual position. Parameterization of the process controller and the position sensor can occur automatically. In this case, the type of the regulated object is automatically recognized and the appropriate adjustment structure with the appropriate optimal set of parameters is determined. The process controller is equipped with additional diagnostic functions for valve control. Diagnostic messages about the valve via status signals are sent according to NE107 (NAMUR) and stored in the form of chronological records. Through diagnostics, the operating conditions of the control valve can be monitored, which, if necessary, allows you to predict maintenance decisions and optimizes the possibilities of using the equipment. Maintenance is carried out through an external maintenance and display module consisting of a graphical display with backlight, as well as a reliable touch keyboard with four buttons with symbols of programmed functions. Maintenance for the user is very simple and intuitive, it is identical to the maintenance of position sensors and process controllers Burkert TopControl 8692/8693. The pneumatic servo system can also be used for single and double-acting drives. It is characterized by a transition to a specific safe mode when the supply of electric or pneumatic auxiliary energy is stopped and it has a very large useful power range at a supply system pressure of up to 7 bar.
