Burkert’s New Intelligent SideControl Brings Flexibility, Precision & Ease-of-Use to Positioner & Process Control Tasks

The SideControl 8792 intelligent positioner unit is extremely flexible and suitable for a wide range of applications; it can be attached directly to an actuator; used as an remote mounted version; or installed in a separately control enclosure. Thanks to its compact and robust IP65/IP67- rated aluminium housing, the SideControl 8792 is ideally suited for use under tough ambient conditions, and in ATEX zones 2/22. In addition, when configured as a process controller (type 8793) with automatic process value evaluation (such as temperature, pressure, filling level and flow rate) and automated parameterisation, the device is the ideal solution for decentralised process control with optional simultaneous feedback to the plant control level.

The design of the 8792 employs the latest 3-wire technology, significantly reducing the cost of the new controller compared to comparable devices based on 2-wire technology. In addition, the positioner’s wide control pressure range, of 1.4 to 7 bar, and the high air flow range of 7 to 100 Nl/min or 150 Nl/min, make the SideControl 8792 extremely versatile, enabling users to reduce their stock of different controllers to a minimum. This cut in inventory costs is complemented by the 8792’s ability to reduce operating costs, as the controller consumes no control air once in its steady position.

The 8792 positioner offers a comprehensive range of functions, and can be easily operated using a large backlit graphic display. The menu control of the SideControl unit is operated through an intuitive 4-key panel that is very simple to use; the operating concept being based on tried and tested Bürkert technology.

“In order to standardise and simplify processes for the operator, the concept is the same as that of Burkert’s digital 8692 electro-pneumatic positioner,” said Sebastian Kundel, segment manager for Hygienic Processing at Bürkert. End- users of SideControl 8792/8793 units connected to control actuators with IEC or VDI/VDE interfaces, and TopControl 8692/8693 devices for use on Bürkert control valves can thus use the same control logic for both types of controllers. This makes day-to-day operation much more efficient.”

Also aiding ease-of use of the 8792/93 is a new version of Burkert’s ProcessTune function. This allows very easy, fast and reliable recognition of the control loop type, and selection of the suitable controller type with optimised parameters.

Initially, Bürkert have launched the standard version of the SideControl 8792, for IEC534-6/VDI/VDE 3845 (NAMUR) adaptions, as well as a version with Profibus DPV1 communications. These will be followed later by units with DeviceNet communications, a remote version for externally connected position sensors, and a low-cost basic version without display for low- cost OEM applications.

Technical Facts About SideControl

The SideControl actuators are suitable for both double-acting and single-acting linear and rotary actuators. Offering the advantage of operating from a low voltage (24V) supply, the 8792 works with industry standard signal inputs and outputs: 4-20 mA/0-5-10V, plus binary I/O, and offers Profibus DPV1 communications. End position detection on the unit is by means of limit switches (or the integrated displacement measuring system) with mechanical position indication also an option. The 8793 process controller version also has 4-20mA input, a PT 100 or frequency signal for the process value input in closed loop control applications. In common with the 8792, it has RS232 port for software updates and parameterisation.
