Temperature Controller

Types of temperature controllers

• On/Off controllers: switch the output fully on or off around the setpoint. Best for simple applications where some temperature swing is acceptable.
• Proportional controllers: reduce output power as the temperature approaches the setpoint, giving smoother control than On/Off.
• PID controllers (Proportional-Integral-Derivative): continuously adjust output to minimize overshoot and offset. Best for fast, precise, or changing processes, and most models offer auto-tuning.

How to choose a temperature controller

Check these points before ordering:

1. Input type: thermocouple (J, K, T, etc.), RTD (Pt100), or analog signal.
2. Output type: relay, SSR drive, 4-20 mA, or 0-10 V, matched to your heater or actuator.
3. Control algorithm: On/Off, proportional, or PID with auto-tune.
4. Size and mounting: DIN-rail or panel cutout (e.g., 48×48, 48×96, 96×96 mm).
5. Supply voltage and communication: 24 VDC or 100-240 VAC, plus RS-485/Modbus if connecting to a PLC or SCADA.
6. Alarms and approvals: alarm relays and CE or other required certifications.

Analog and digital temperature controllers

Browse both analog and digital models. Digital PID controllers suit most modern applications, while analog models remain useful for simple, low-cost control.
