The Extech 48VFL11 Temperature PID Controller includes fuzzy logic enhanced PID and a soft start feature to prevent heaters from cold starts. PID plus fuzzy logic can handle even the most demanding applications, reducing overshoot, undesirable process variations, and drift. The gentle start function is appropriate for operations used in the thermoplastics industry, which need careful, precise, and slow heating of the product. It supports thermocouple and RTD inputs. Includes a single stage ramp and soak program with a ramp-to-set point limit that can be used with the soft start feature to meet essential process demands. Complete with mounting bracket hardware and screw terminals for simple wiring. Also available with a 4-20 mA output (48VFL 13).
