1/4 DIN Temperature Controllers

FuzyPro 1/4 DIN Temperature Controller Heat/Cool Controllers can easily be configured to provide precise control. Thanks to its 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. in-panel depth is the shortest of any similar function control available. 

FuzyPro 1/4 DIN Temperature Controller Heat/Cool Controllers Features:

  • Automatic tuning of PID parameters
  • Selectable input, heating and/or cooling outputs, degrees C or F 
  • 2 optional alarms, large displays 5/8-in. and 1/2-in.
  • Sealed mylar front panel, external lockout 
  • All control parameters adjustable from front panel 
  • Automatic/manual mode operation 2-in. in-panel depth
