1/4 DIN Fuzzy Logic Heat/Cool Temperature Controllers

1/4 DIN, Fuzzy Logic Heat/Cool Temperature Controllers, Fuzzy Logic Heat/Cool Controllers, Fuzzy Logic Temperature Controllers, FuzyProFuzyPro 1/4 DIN fuzzy logic Heat/Cool temperature controller is easily be configured to provide precise control. The advanced Smarter Logic "Fuzzy" allows processes to be controlled better than ever before, with virtually no initial overshoot or temperature variations.

As the control detects a process disturbance the fuzzy logic continuous decision making function quickly returns the process value to the setpoint. The large dual displays allow the set point and process value to be visible at all times. In addition self-diagnostic capabilities, sensor linearization and cold junction compensation are all performed by the powerful, single chip microprocessor. The 2" in panel depth is the shortest of any similar function control available.

1/4 DIN Fuzzy Logic Heat/Cool Temperature Controllers Features:

  • Automatic tuning of PID parameters

  • Selectable input, heating and/or cooling outputs, ºC or ºF

  • 2 optional alarms, large displays 5/8" and 1 /2"

  • Sealed mylar front panel, external lockout

  • All control parameters adjustable from front panel

  • Automatic/manual mode operation 2" in panel depth
