[0033] Working Principle: In use, the controller body 1 is first installed in the desired location. Multiple sets of wiring ports 3 on the wiring panel 2 at the front of the controller body 1 are then connected to the wiring terminals of external devices to connect them. The operator can open the protective plate 6 above the wiring panel 2 by moving it within the sliding cylinder 4 via the inner rotating rod 5 using the upper pull plate 9. The end of the device to be connected is then passed through the outer perforation 7 inside the protective plate 6 and into the wiring port 3 on the wiring panel 2. The rubber gasket 8 inside the outer perforation 7 isolates it from external dust. This improves the sealing effect of the wiring parts of the controller body 1. After connection, pull down the pull plate 9 to cover the surface of the wiring panel 2 with the protective plate 6.

Hole 16, then the mounting base frame 13 is bolted to the area to be installed on the equipment, and the overall stability of the mounting base frame 13 is improved by the fixing rod 14. Then, the bottom end of the PLC controller body 1 is connected to the connecting plate 17, and the fixing bolts are inserted into the screw holes 18 inside the connecting plate 17, thereby fixing the controller body 1 and the connecting plate 17 together. Finally, the controller body 1 is bolted to the connecting plate 17 at the front end of the mounting base frame 13, reducing the difficulty of directly installing the controller body 1. If the controller needs to be disassembled, the controller body 1 can be directly connected to the connecting plate 17. The board 17 can be removed, simplifying the overall installation and disassembly steps of the controller. The assembly and disassembly are easier. When installing the mounting base 13, it can be reinforced by the base 19 at the rear end of the mounting base 13. The extension rod 21 inside the inner groove 20 at the rear end of the base 19 is connected to the part to be installed, and the patch 22 at the rear end of the extension rod 21 enhances the stability of the connection. This makes the overall stability of the PLC controller stronger during installation, preventing installation failure due to shaking of the controller body 1, and improving the installation efficiency of the PLC controller.
