Thanks to its compact design, the universal 8611 controller is especially designed for compact control system applications. It is compatible and tested with all Bürkert proportional valves and sensors and can be connected with every non-Bürkert Control valve by standard signal (4…20 mA, 0…10 V or PWM-output). The Proportional & Integral (PI) process controller is equipped with many additional functions. The process value feedback can be supplied as one of three analogue inputs; a standard signal (4…20 mA/0…10 V), frequency or RTD signal; directly to the universal controller. The process switching points can be set via a 4…20 mA or 0…10 V signal or with the keypad. For temperature specific control, it is possible to set a cascade structure with both temperature and flow as inputs. Thanks to the proportional control capabilities, a wide range of control functions can be performed in a variety of liquids and gas mediums.
