The Extech 48VFL11 Temperature PID Controller offers fuzzy logic enhanced PID and a soft start feature that protects heaters from cold starts. PID plus fuzzy logic tackles even the most demanding applications, eliminating over-shoot, unwanted process fluctuations, and drift. The soft start feature is ideally suited for processes such as those employed in the thermoplastics industry: where careful, exact, and slow heating of product is required. It accepts thermocouple and RTD inputs. Includes single stage ramp and soak program with ramp-to-set point limit that can be combined with the soft start feature for critical process demands. Complete with mounting bracket hardware and screw terminals for easy wiring. Also available with 4-20 mA output (48VFL13).
