What is the structure of the PLC control cabinet?
The total size of the PLC control cabinet is very large, but the structure is very compact and fully functional. If the general control box only has a separate actual operation, the PLC control cabinet can not only complete the operation of a single cabinet, but also complete the other operation of several cabinets, which can be extremely integrated into several cabinets.

Lc control cabinet wiring specification control wiring and communication wiring
The plc control cabinet wiring specification must be observed when the control cabinet is designed into production. Before that, we explained three types of control cabinet wiring: power wiring, control wiring and communication wiring. Because power wiring is rarely contacted in the production process of PLC control cabinet, today we will explain the specifications of control wiring and communication wiring in the wiring specification of PLC control cabinet, as well as some matters needing attention in the wiring process. To ensure the safety and stability of the production control cabinet.

Basic principles of PLC control design
In order to better grasp the use and design of PLC, it is generally necessary to have certain basic knowledge, such as electrotechnics (including electrical foundation, electrical machinery, electrical control), electronics (including digital circuits, analog circuits) and computer foundation.
What are the factors that affect the heat dissipation of the frequency conversion control cabinet
Frequency conversion control cabinet is relatively common in control equipment. Now both electronic components and equipment need regular maintenance, otherwise it may affect the luck and service life of the equipment. The more common problem in frequency conversion control cabinet is abnormal heat dissipation. What are the factors that affect the heat dissipation of frequency conversion control cabinet?
Laying direction of wire and cable of inverter control cabinet
The direction of cable laying is still to consider the interference problem, and it is also an auxiliary effective measure. When the control system works in the transmission of weak electric signals, it is possible to distort the transmitted signals by external interference or internal interference, especially for analog signals, the distortion is more serious, while for digital signals, the impact is small. Regardless of the form, the defense measures of the control system should be as perfect as possible.
