Thanks to its compact design, the universal 8611 controller is especially designed for compact control system applications. It is compatible with a wide range of proportional control valves and connects with an electropneumatic servo-system for pneumatically actuated process control valves. The PI process controller is equipped with many additional functions. The actual process value can be supplied as one of three inputs; a standard current (4-20 mA), frequency or Pt100 signal directly to the universal controller. The process switching points can be set via a 4-20 mA signal or with the keypad.
