AI-719/709 intelligent temperature controller adopts advanced AI intelligent PID control algorithm, no overshoot, with manual / automatic non-disturbance switching function and soft start function. It can use Utech's new generation 14-bit resolution 0.2% high precision current output module X3/X5, which has higher current output accuracy than the old product. The sampling rate is doubled compared with the previous generation of products, and the minimum control cycle is as short as 0.24 seconds, which improves the control accuracy of fast-changing objects. The advanced modular structure provides rich output specifications to meet the needs of various applications and is delivered quickly and maintained conveniently.
This manual describes the AI‑719/709 artificial‑intelligence regulator produced by Yudian. It covers the modular hardware design, input selection, output modules, communication interfaces and advanced functions such as self‑tuning, manual/auto disturbance‑free switching and soft‑start.
Detailed sections provide wiring diagrams, parameter settings, maintenance procedures and warranty information, enabling users to install, configure and service the regulator in various industrial applications. This manual is written in Chinese.

The regulator supports thermocouples (K, S, R, E, J, T, B, N, WRe3‑WRe25, WRe5‑WRe26), resistance sensors (Cu50, Pt100), linear voltage, and 0‑20 mA or 4‑20 mA current inputs.
Set the soft‑start time (CtI) to 0.5 s and the power‑on ramp (OPrt) to 5 s in the parameter settings to enable soft‑start and reduce inrush current.
Yudian provides a five‑year free repair warranty from the date of shipment.
