How to Correctly Configure a PLC Control Cabinet?
How to correctly set up a PLC control cabinet? To ensure the system's reliability and safety, it is essential to thoroughly understand the setting environment before designing the system and then proceed with its construction. At the source, efforts should be made to minimize stress factors (temperature, humidity, vibration, impact, corrosive substances, overvoltage, noise, etc.) on the PLC system. However, the extent of these preventive measures should be determined based on the impact of potential failures, the setting environment, and the cost of implementing these measures. By implementing preventive measures in advance, system stability can be improved, and long-term operational efficiency can be enhanced.
The PLC control cabinet enables intelligent equipment operation and full-process mechanical automation, featuring advantages such as stable quality, scalability, and strong anti-interference capabilities, making it a cornerstone and lifeline in industrialization. It can also be customized to design PLC control cabinets, frequency converters, and other solutions tailored to customer needs, meeting user requirements. Additionally, it can be paired with industrial touchscreens to achieve effortless operation. The equipment can further communicate with DCS systems via protocols like Modbus and Profibus, enabling data transmission, as well as control and monitoring through industrial PCs and Ethernet interfaces. However, the configuration of the PLC control cabinet can be adjusted based on requirements, typically set according to customer needs. Yet, the following aspects must be included in the PLC control cabinet setup.
1. Power supply: DC 24V, single-phase AC 220V (-10%, +15%), 50Hz.
2. Waterproof rating: IP41 or IP20.
3. Natural Conditions: The operating temperature should be between 0°C and 55°C, avoiding direct sunlight exposure. The ambient air humidity must remain below 85% (no condensation). Avoid strong vibration sources and frequent or continuous vibrations within the 10-55 Hz range. Prevent exposure to corrosive or flammable gases.
How to Design an Intelligent PLC Control Cabinet?
The PLC intelligent control cabinet involves installing the PLC control module inside a metal cabinet according to the design drawings, wiring, and conducting tests to ensure smooth operation of each circuit. After assembling the control cabinet on-site, the system is programmed locally to achieve the effect of key equipment in the intelligent control system. The PLC intelligent electrical control cabinet is similar, but there are differences in design and cabinet configuration.
(1) Install structurally complex and heavy power equipment beneath the mounting plate, while placing heat-generating equipment on the top or rear of the PLC intelligent control cabinet. This rational layout facilitates transportation, prevents parts from falling due to force, and enhances heat dissipation within the cabinet.
(2) High-voltage and low-voltage wiring must be separated to prevent interference.
(3) Items requiring regular maintenance and inspection: The setting of electrical equipment components should be appropriate. As a manufacturer of PLC intelligent control panels, HuapuTuo's professional technicians fully consider the operational process of on-site personnel during design, meeting ergonomic requirements.
