8. PLC-11 type touch screen training component

7-inch color touch screen (TPS7062KX), equipped with communication download programming cable, touch screen and PLC communication cable, development configuration software; AC contactor; intermediate relay; auxiliary contact; thermal relay; button (strong power); emergency stop; travel switch; time relay.

9. PLC-20 motor guide rail, optical encoder speed measurement system and digital tachometer\brake system

Includes three-phase squirrel cage asynchronous motor: 380V/△, speed less than 1500RPM, power less than 100W, optical encoder speed measurement system (equipped with Omron 1024 photoelectric encoder), digital tachometer and stainless steel guide rail for fixing the motor. The stainless steel guide rail has good flatness, which can ensure that the concentricity between the motor and the encoder does not exceed ±5 wires, and the motor has low noise during operation; it has voltage feedback signal; it also has photoelectric encoding signal output, including two channels A and B.

10. Electrical control module

11. Experimental connection line

According to the characteristics of different experimental projects, two different experimental connection lines are equipped. The strong current part adopts a high-reliability sheath structure pistol plug connection line (there is no possibility of electric shock), and the oxygen-free copper wire is drawn into a hair-thin multi-strand wire to achieve the purpose of ultra-softness. It is covered with a nitrile polyvinyl chloride insulation layer, which has the advantages of softness, high pressure resistance, high strength, anti-hardening, and good toughness. The plug adopts a solid copper piece with a beryllium light copper shrapnel, which is safe and reliable in contact; the weak current part adopts an elastic beryllium light copper exposed structure connection line. Both wires can only be matched with the socket of the corresponding inner hole, and cannot be mixed, which greatly improves the safety and rationality of the experiment.

12. Configuration software

Provide TIA Portal software, MCGS simulation software, experimental software, etc.

13. Computer

CPU i5/8G DDR4/240G SSD, equipped with genuine operating system and TIA Portal software.

14. Safety protection

1) The three-phase AC power output is equipped with dual overcurrent and short-circuit protection functions of electronic circuits and fuses. When the output current is greater than 3A, the power supply can be disconnected and an alarm indication will be given;

2) The experimental table uses three types of experimental wires, which cannot be plugged into each other. Strong current uses fully plastic enclosed safety experimental wires, weak current uses metal bare experimental wires (the actual core copper diameter is larger than the strong current wire), and the observation hole uses 2# experimental wires to avoid the possibility of students connecting strong current to weak points by mistake;

3) The AC and DC power supplies of this PLC training platform are equipped with overcurrent protection function.
