1/8 DIN Fuzzy Logic Heat/Cool Controllers

1/8 DIN, Heat/Cool Controllers, Fuzzy Logic, FuzyProFuzyPro 1/8 DIN Fuzzy Logic Heat/Cool Controllers are designed to provide precise control with a quick and easy set up procedure. SMT and microprocessor technology provides all these features plus reliability and economy. LED index indication allows full viewing and selection of parameters.

The dual display allows set point and process value visibility at all times. An advanced software algorithm automatically calculates all PID parameters to eliminate complicated manual tuning efforts. Automatic tuning can be bypassed if manual tuning is preferred. An open-loop, manual mode can be initiated if the sensor fails. Front panel electronic calibration sensor linearization self-diagnostic capabilities and cold junction compensation are all performed by the single chip microprocessor. The in-panel depth is only 2-1/2".
