Temperature control new change - da DTE10T power plastic extruding machine to realize intelligent temperature control

Recently, the leading brand - in industrial automation module thermostat DTE10T designed for a plastic extruding machine user multi-channel temperature control, convenient and effective help users solve the problem of equipment volume. The application of this new product, is expected to help the extrusion machine equipment to more compact and flexible, break through the application limitation, upgrading industry change.

With PLC, man-machine interface and other products are constantly applied to the plastic extrusion machine, intelligent control and the centralized control concept has been accepted by the masses of users. The traditional temperature control scheme can't meet the demand of molding machine equipment upgrade, in rich and highly humanized DTE10T function, its dual PID control, 485 communication standard, small size and can be used rack modular installation, satisfy the needs of users multi-channel temperature control, and a large number of saving the installation space, fully staffed, user requirements is very suitable for the plastic industry.

First, DTE in structure to meet the needs of users centralized control. As automation equipment in the trend of miniaturization, modularization, natural to the requirement of temperature control parts are more tend to be nimble, convenient, and module integration. DTE's design is perfect to fit the trend, which can be successfully into plastic extruding machine field.

Secondly, in terms of temperature control double PID method improves the temperature control effect. Thermostat provides two set of output, a set for heating, cooling for another group. Extruder during extrusion materials produce a lot of heat because of friction, the heat is the main reason for the temperature overshoot, define DTE10T SUB1 outlet for cooling output control, using double PID calculation, the temperature is not through the set value, the thermostat can start cooling fan, avoid high temperature or unstable. Of dual PID control also joined the movement area, namely in a certain temperature range, neither the calories or for cooling action, OUT1 and OUT2 no output, completely on spontaneous heat, external heat to sustain the heat balance of material flow and heat loss. DTE each channel isolated, parameter setting and influence each other. Each channel can be set in a separate area parameters such as. This double PID control method in the two groups of alternate or jointly run output can guarantee the stability of control temperature, under the condition of bring substantial improvements for extrusion temperature mechanical control effect.

Third, DTE parameter Settings can be used for PC software to complete, the fixed area need to analysis and combined with the actual working condition of parameters, such as setting, very convenient. Plastic extruder generally can be set up between 0 to 2, the PID parameters can be use AT completion. While cooling hardware architecture and alarm in the same way, but the cooling fan output is obtained by the PID arithmetic, compared the two type of alarm cooling mode, can be more accurate to ensure the rationality of the cooling output, effectively restrain temperature overshoot phenomenon, in the mode of temperature control is a higher level.

In addition, as a multi-channel temperature control product, DTE10T standalone 8-way temperature control channels are available, meet the demand of extruder needs multi-channel temperature control channel, the other to provide standard Modbus communication protocol, and PLC and man-machine communication, suitable for various industrial applications.
