How It Works

The REX-C100FK07 monitors the temperature via a K-type thermocouple or RTD sensor. Based on the difference between the set temperature (SV) and current temperature (PV), it adjusts the output through PID control. This minimizes overshooting and ensures stable and accurate temperature maintenance. The auto-tuning feature automatically determines the optimal PID parameters for your system.
