Frequently Asked Questions

What is the difference between PID and On/Off temperature controllers?

PID controllers continuously calculate the error between setpoint and process variable and adjust the output proportionally, integrally, and derivatively to minimize overshoot and achieve stable control. On/Off controllers simply switch the output on or off when the process variable crosses the setpoint, leading to oscillation around the setpoint. PID control provides smoother, more accurate temperature regulation, especially in dynamic systems, reducing wear on actuators and improving product quality.
Yes, the REX C100 accepts multiple input types including thermocouples (K, E, J, T, S, R, etc.) and PT100 RTDs. It features a universal input selection that can be configured via the front panel or software, allowing flexibility for different sensor installations. The controller also includes cold junction compensation for thermocouples to ensure accurate measurement across a wide temperature range.
Absolutely. The REX C100 offers an optional RS485 communication module that supports Modbus RTU protocol, enabling seamless integration with PLCs, HMIs, or SCADA systems. This allows for remote setpoint adjustment, parameter monitoring, and data recording, facilitating centralized control and predictive maintenance.
Autotuning, also known as self-tuning, initiates a controlled cycling process where the controller applies a series of steps to identify the process dynamics. It then calculates optimal PID parameters based on the measured response. The user can trigger autotuning easily via the front keypad of the REX C100. This feature significantly simplifies setup and ensures optimal control from the start.
The REX C100 is designed for long-term reliability, with an expected operational life of over 10 years in typical industrial conditions.

Michael Chen

We replaced our old temperature controllers with the REX C100 in our injection molding machines. The difference is remarkable. The temperature fluctuation dropped from ±5°C to within ±1°C, which significantly reduced our defective product rate. The autotuning feature saved us hours of manual tuning. The build quality feels robust, and installation was straightforward. Highly recommended for any precision-critical application.
