Flow Controller – eCONTROL – Universal Controller Type 8611

  • Thanks to its compact design, the universal type 8611 controller is especially designed for compact control system applications.
  • The Proportional and 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.

Key features

  • 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).
  • Sensor signals 4-20 mA, 0-10 V as well as frequency, PWM as well as 4-20 mA control output
  • Nominal width/mechanical cable connection Wall-mounting, control cabinet mounting, and valve-mounting version
  • Temperature range: 0 to 70 °C (ambient)
  • Protection class: IP65

Application areas

  • Hydrogen production – Electrolyser
  • Hydrogen use – Stationary fuel cells, Mobile fuel cells
  • Hydrogen test benches – Industrialization, Scale up
  • Hydrogen infrastructure
