1. The AI-2 series is an easy-to-operate, easy-to-learn, user-friendly, and affordable temperature controller.

2. Designed for industries such as plastic machinery, food machinery, packaging machinery, ovens, and environmental test equipment.

3. 0.3% measurement accuracy, dual three-digit/four-digit energy-saving LED digital display.

4. APID auto-tuning adaptive control algorithm with no overshoot or undershoot, achieving ideal control performance; can also be set to ON-OFF mode for displaying an alarm.

5. In addition to the traditional AT auto-tuning function, it also supports the advanced Yudian AAT rapid auto-tuning of PID parameters, which can significantly reduce equipment commissioning time in most cases.

6. Supports multiple thermocouple and RTD input specifications; supports multiple output specifications, including SSR solid-state relay output, high-capacity relay output, and linear current output.

7. Ultra-low power consumption, with instrument power usage around 0.2~0.3W when output is off.

8. Lightning-proof power protection, the instrument remains undamaged even under prolonged 380V AC misconnection.
