Product model used:AI-208D21G1L0

Process description:Yudian AI-208 is applied in heat treatment injection molding machine zone heating. The instrument has a measurement accuracy of 0.3 level, temperature adjustable from 0-450 ℃, small size of 45x45mm, and controls the output of 5V DC voltage signal from solid-state relay. It is equipped with one relay upper and lower limit over temperature alarm. Each zone control uses independent sensors to independently sample and output control the temperature of each electric brick, improving the flexibility of control.

On site application:Due to the varying load power of the hot melt glue machine, the setting interface has a self-tuning function button; Implement the relationship between 0 and 1 through self-tuning; For familiar systems, it is possible to directly input known correct P, I, D, CtI without activating the self-tuning (AT) function. Self tuning is to enable the thermostat to perform ON/OFF (positional) control. After 2-3 oscillation cycles, the internal microprocessor of the instrument automatically calculates control parameters such as P, I, D based on the oscillation generated by positional control, analyzing its period, amplitude, and waveform. The parameter values obtained by tuning the system under different given values are differentexhaustSimilarly, before performing the self-tuning function, the given value should be set tocommonly usedIn terms of value or intermediate value, if the system is an electric furnace with good insulation performance, the given value should be set at the maximum value used by the system, and then the operation function of starting self-tuning should be executed.

Problem solved for customers:The control of heating elements adopts AI fuzzy control technology, reducing the fluctuation of PID regulation, minimizing control lag, improving equipment reliability, and shortening equipment production debugging time.

Value achieved for customers:The temperature control module adopts a single PID temperature control module, and the temperature control module body is equipped with SSR voltage temperature control output, so the integration is very high, and the control performance is greatly improved, while the cost is greatly reduced. By using the AI-208D21G1L0 model for temperature control, the heating plate can be automatically adjusted to the predetermined temperature according to the set temperature.

Customer review:Yudian's single channel PID temperature control instrument improves the flexibility of product control and the reliability of equipment, with a very high degree of integration, enabling the enterprise to achieve cost reduction and efficiency improvement optimization, which is worthy of praise.
