New Original FOTEK NT-20R Relay Output Digital PID Temperature Controller<\/h1>\n

1. Product Overview<\/h2>\n

The FOTEK NT-20R belongs to the NT series fuzzy + PID intelligent digital temperature controller. It adopts microprocessor control technology and supports multiple universal temperature sensor inputs. This model is equipped with relay control output and dual alarm outputs. It can automatically calculate optimal PID parameters via auto-tuning function to maintain stable temperature. Widely applied in heating furnaces, packaging machinery, injection molding equipment, food processing machines and various industrial heating\/cooling automation systems. The supplied unit is brand-new original genuine FOTEK product made in Taiwan.<\/p>\n
