New changes in temperature control - Delta dte10t helps plastic extruders realize intelligent temperature control

recently, delta modular temperature controller dte10t, a leading brand of industrial automation, designed a multi-channel temperature control scheme for a plastic extruder user, which is convenient and effective to help users solve the problem of equipment volume. The application of this new product is expected to help the extruder equipment become smaller and more flexible, break through the limitations of application, and trigger changes and upgrades in the industry

with 2. Automatic return: the automatic identification experiment has made great efforts to ensure that PLC, human-machine interface and other products are constantly applied to plastic extruders. The concept of intelligent control and centralized control has begun to be accepted by the majority of users. The traditional temperature control scheme can not meet the upgrading needs of plastic machine equipment. Delta dte10t has rich functions and is very humanized. Its dual PID control, standard 485 communication, small size and modular installation in the cabinet can not only meet the needs of users for multi-channel temperature control, but also save a lot of installation space, killing many birds with one stone, which is very suitable for the needs of users in the plastic industry

first of all, DTE meets the needs of centralized control of users in structure. With the trend of miniaturization and modularization of automation equipment, the requirements for temperature control naturally tend to be dexterous, convenient, and modular integration. DTE's various designs perfectly conform to this trend, which can successfully enter the field of plastic extruders

secondly, in terms of temperature control mode, the dual PID mode improves the temperature control effect. The thermostat provides two sets of outputs, one for heating and the other for cooling. When extruding materials, the extruder generates a lot of heat due to friction, which is the main cause of temperature overshoot. Define the sub1 output port of dte10t as the cooling output control, and use double PID calculation. When the temperature does not overshoot the set value, the thermostat can start the cooling fan in advance to avoid excessive temperature or instability. The double PID control also adds a non action area, that is, in a specific temperature range, there is neither heat supplement nor cooling action, out1 and out2 have no output, and the heat balance is completely maintained by the self heating, external heat dissipation and heat loss of material flow of the system. Each channel of DTE is isolated from each other, and the parameter settings do not affect each other. Each channel can set parameters such as immovable zone separately. This dual PID control mode can ensure the stability of the control temperature when the two groups of outputs operate alternately or jointly, which greatly improves the temperature control effect of the extruder

third, DTE parameter setting can be completed by using special PC software. Parameters such as fixed area need to be analyzed and set in combination with the actual working conditions on site, which is very convenient. Plastic extruders can generally be set between 0 and 2, and PID parameters can be automatically completed with the help of at. Although the cooling hardware architecture is the same as the alarm mode, the output of the cooling fan is obtained by PID calculation. Compared with the two digit alarm cooling mode, it can more accurately ensure the rationality of the cooling output and effectively suppress the phenomenon of temperature overshoot, which can be described as a step up in the temperature control mode

in addition, as a multi-channel temperature control product, dte10t single machine can provide 8-channel temperature control channels, which meets the needs of the extruder for multi-channel temperature control channels. It also provides a standard Modbus communication protocol to communicate with PLC and man-machine, which is suitable for applications in various industries
