85–265V AC, 50/60 Hz (Standard); 24V DC (Optional). Power Consumption: Less than 5 VA. Display Type: Dual-line 4-digit LED display (PV and SV). Sampling Cycle: 500 milliseconds. Measurement Accuracy: ±0.5% of full scale. Supported Input Sensors Thermocouples: Type K, J, E, T, R, S. RTD Sensors: Pt100, Cu50. Output Options Relay Output: SPST contact, 250V AC / 3A (Resistive load). SSR Drive: 12V DC, 30mA max (For Solid State Relays).
Since I cannot link to a live file here, the following steps are based on the standard engineering protocols used in most documents. For exact key sequences, refer to your specific model's PDF.
Generally 100-240V AC. Ensure proper voltage to prevent damage.
To change input types, alarm settings, or PID values, you must enter the Parameter Setting Mode.
Note: Always consult the specific wiring diagram on the side of your Fourtech unit, as pin numbers can vary between models (e.g., CH402 vs. CH102). Typical Wiring Layout
For Thermocouples: Connect positive (+) to terminal 9. Connect negative (-) to terminal 10. 3. Front Panel Interface and Button Navigation
Fourtech temperature controllers are widely used in industrial and consumer applications for precise thermal regulation. Whether you are using a Fourtech PID controller for an oven, kiln, or cooling system, understanding the setup and programming is crucial for efficient performance.
For Pt100 (RTD): Connect the red wire to terminal 8. Connect the two blue/white wires to 9 and 10.
When something fails within the heating or sensing circuit, the Fourtech display will flag an error code in the PV window.
Improper wiring can damage the instrument or pose safety hazards. Always isolate the power source before starting the installation.
: This is usually the first value you see. Use the arrow keys to adjust your target temperature.
While layout configurations can vary slightly by specific model numbers, standard Fourtech controllers share a universal terminal architecture:
