Yudian AI-509 (48*48mm)

A. Product Overview

The Yudian AI-509 Temperature Controller is a digital PID controller used to maintain process temperature with high accuracy and stable control performance. It is designed for industrial heating and cooling applications where precise temperature regulation is required.

This controller supports multiple sensor inputs such as K, S, R, E, J, N thermocouple and Pt100 RTD. It has a clear dual display that shows the process value and set value, making it easy for operators to monitor and adjust temperature settings.

The AI-509 is available in different panel sizes such as 96 x 96 mm, 72 x 72 mm, 48 x 48 mm, 48 x 96 mm and 96 x 48 mm, which makes it suitable for different control panel designs. Output options include relay output, SSR voltage output, TRIAC output, thyristor trigger output and linear current output depending on the selected model configuration.

It is commonly used in plastic machinery, food machinery, packaging machinery, industrial kilns, furnaces and environmental testing equipment.

B. Working Principle

The Yudian AI-509 works by continuously reading the temperature from a connected thermocouple or Pt100 sensor. The measured temperature is shown as the process value on the upper display, while the desired temperature setting is shown as the set value on the lower display.

When the measured temperature is lower or higher than the set value, the controller operates the output according to the selected control mode.

In On-Off control mode, the controller switches the output on or off based on the temperature difference and hysteresis setting. This mode is simple and suitable for basic heating or cooling applications.

In AI PID control mode, the controller uses an artificial intelligence control algorithm with auto tuning. During auto tuning, the controller studies the heating or cooling behavior of the process and calculates suitable PID values. This helps reduce overshoot and improves temperature stability.

The controller can drive heaters, contactors, SSRs, thyristors or other control elements depending on the output module selected. Alarm functions can also be configured for high limit, low limit, deviation high and deviation low temperature conditions.

C. Why It Is Used

The Yudian AI-509 PID Temperature Controller is used when a process requires stable and accurate temperature control. It helps maintain the required temperature automatically and reduces manual adjustment.
