Type 8611 controller can connect to non-Bürkert control valves by 4-20 mA, 0-10 V or PWM output. The PI controller has many functions and value feedback can be supplied as a standard signal (4-20 mA/0-10 V), frequency or RTD signal, or directly to the universal controller. Switching points can be set via 4-20 mA or 0-10 V signal or with the keypad. It is possible to set a cascade structure with both temperature and flow as inputs.
