[0002] PLC control cabinet is a programmable control with the characteristics of compact structure, stable operation and complete functions. PLC control cabinet has protection functions such as overload, short circuit and phase loss protection. PLC control cabinet can realize multi-cabinet combined braking according to the actual scale, and can also realize braking operation alone. PLC control cabinet can be used in braking places of various sizes and is widely used in industrial braking and building braking.

[0003] In the prior art, the bottom cable inlet of the PLC control cabinet is mostly designed with right-angle edges. The insulation layer on the surface of the cable is easily scratched during installation, and leakage problems are very likely to occur. The PLC control cabinet is generally installed in the control room for combined discharge, with a small space and difficult heat dissipation. The PLC control cabinet accumulates too high a temperature for a long time, which will cause the components and lines to age quickly. For this reason, we provide a PLC control cabinet with circulating ventilation to solve the above problems. Utility Model Content
