RE41, RE42, RE43, RE44

The RE4x series process controllers are distinguished by the innovative PID & Fuzzy Logic algorithm. This allows the setpoint to be reached in the shortest time with a minimum overshoot during warm-up or during external interference. The variety of built-in functions enables the use of these controllers in demanding control processes.
