8611 Universal Process Controller
Brand: Burkert Fluid Control Systems
The universal 8611 controller is especially designed for compact control system applications.
It is compatible and tested with all Burkert proportional valves and sensors and can be connected with every none-Burkert Control valve by standard signal (4-20 mA, 0-10 V or PWMoutput). The proportional & Integral (PI) process controller is equipped with many additional functions.
The process value feedback can be supplied as one of three Analog inputs; a standard signal (4-20 mA/0-10V), frequency or Pt100 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.
Features- Continuous, 2-point, 3-point and On/Off control
- Ratio control function
- Sensor inputs (4-20 mA, 0-10 V, frequency, Pt100)
