The AI-208 is an artificial‑intelligence temperature controller designed for light‑industry equipment, ovens, laboratory devices, and heating/cooling systems. It offers easy operation, built‑in SSR or relay output, delay functions to protect compressors, and a global 100‑240 VAC power supply.
The manual explains panel layouts, input selection (K, E, J, N thermocouples or Pt100), wiring diagrams, parameter tables, and detailed procedures for setting values, adjusting parameters, and performing the auto‑tuning (AT) function. This manual is written in Chinese.
| Measurement accuracy | 0.3 °C |
|---|---|
| Measurement range | 0‑999 °C (K, E, J, N) or 0‑800 °C (Pt100) |
| Input types | K, E, J, N thermocouples or Pt100 |
| Power supply | 100‑240 VAC, 50‑60 Hz |
| Power consumption | < 2 W |
| Operating environment | Temperature 0‑60 °C, Humidity 0‑90 %RH |
| SSR output | 5 VDC / 30 mA |
| Relay output | 250 VAC / 5 A or 30 VDC / 5 A (NO) |
In the basic display state, press the "( )" or "(*)" keys to increase or decrease the value; hold the key for faster adjustment.
Press the (4) key for about 2 seconds to enter AT mode, then press (^) to change OFF to ON and press (@) to confirm; the controller will calculate PID parameters automatically.
The controller supports K, E, J, N thermocouples and Pt100 resistance temperature detectors, selectable via the input setting.
The device provides a measurement accuracy of 0.3 °C (0.3 % of full scale).
