Bürkert ECONTROL – Universal Controller

Universal controller Type 8611 is ideally suited for the construction of compact control systems thanks to its compactness. It is compatible and has been tested with all Bürkert proportional valves and sensors, and can be used in combination with all non-Bürkert control valves with a standard signal (4-20 mA/0-10 V/PWM output). The process controller with PI behaviour comes with a variety of auxiliary functions. The process actual value can be connected to one of the three analog inputs of the universal controller as a standard signal (4–20 mA / 0–10 V), a frequency signal, or as a signal from a Pt100 resistance temperature sensor. The process setpoint can be specified via a current or voltage standard signal or via the keyboard. Specifically for temperature control tasks, there is the option to create a cascade structure with underlying flow control. A wide range of control tasks in fluid technology can be implemented for both liquid and gaseous media by enabling the control of proportional valves and process valves.
