UniMAT Application in high optical temperature machine

I. Introduction of equipment:

The mold temperature machine is developed to assist a OEM customer, and is used for injection molding machine operation. Originally OEM customers used traditional electrical equipment control method to make a prototype, according to the system requirements, control pumps, water valves and some alarm display needs a series of corresponding switches and indicators, but also a large number of relays, wiring is very troublesome. The commissioning and trial results of the prototype are not ideal, so PLC is adopted to control the operation of the device. Obviously, in the case of meeting the system control requirements, customers preferred the cheap UniMAT 224 CPU plus UniMAT 4TC module and 16DO module to achieve control.

Control requirements:

1). control the hot water or cold water discharge according to the temperature feedback or setting time of the road.

2). The control flow is divided into manual control and automatic control. The two control modes can not be carried out simultaneously. All actions must be completed when the pump is started.

3). monitor and control the operation of the device through the touchscreen and display the alarm.

4). it is required that several sets of set time and temperature parameters can be saved and read directly.

3.Conclusion,

Using UniMAT CPU224 and extended module to control, not only programming is simple, wiring is simple, maintenance is also convenient, not only to ensure the stability of the control, but also to save costs.
