Detailed content
- Functional Characteristics:
- It is equipped with a 14 – segment 5 – digit color LCD display with a bar graph, which can clearly display process values (PV), set values (SP), and other key data, and the screen color can be changed according to the status.
- It has 8 control algorithms, such as ON/OFF, PID (continuous/time – proportional), heating/cooling, and position proportional control, to meet various control needs.
- The standard ladder diagram sequence control function can replace a small – size PLC to realize simple logic control, and the programming can be completed through LL50A software.
- It has rich alarm functions, including PV high/low alarm, deviation alarm, rate – of – change alarm, heater burnout alarm, etc., to ensure the safety of the production process.
- It supports feedforward control and cascade control, which can effectively compensate for interference variables and improve control accuracy.
- Application Scenarios: It is widely used in the heat treatment industry for controlling the temperature of heating furnaces and quenching equipment to ensure the stability of material properties; in the chemical industry for monitoring and controlling the temperature and pressure of reaction kettles to prevent over – limit operation; in the food processing industry for adjusting the temperature of sterilization kettles and baking equipment to ensure food safety and quality; in the semiconductor manufacturing industry for accurately controlling the temperature of etching and deposition processes to improve product yield.
