For the switch field, many friends who do security are familiar with it. Switches are divided into commercial network switches and industrial Ethernet switches. In order to meet the flexible and changeable industrial environment and anti-interference aspects, industrial There is a particularly big gap between switches and business switches, and the functions of industrial switches are more practical in comparison. Let’s take a look!
There is no essential difference between itself and commercial networks in terms of data link layer, network layer, protocol layer, etc., but for the real-time requirements of industrial control, industrial Ethernet solves the real-time communication, network security, intrinsic safety, and safety explosion-proof Technical issues such as technology, and adopting some measures suitable for industrial environments, such as waterproofing, anti-vibration... The core is still not essentially different from commercial Ethernet, which is the same as the difference between a PC and an industrial computer.
1. The difference in appearance
Industrial switches generally use a fanless enclosure fan mode, and basically use a metal enclosure, which has higher strength. Ordinary switches generally use a plastic enclosure with higher strength and use a fan cooling mode.
2. The use environment capabilities are not exactly the same
Industrial switches can adapt to a low temperature of 40°C to 85°C, and have excellent dust and humidity resistance. The protection level is above IP40. The scope of use is more common, and it can be installed and used under any dangerous conditions. Generally speaking, the operating temperature of ordinary switches is between 0°C and 50°C, and they have basically no dust and moisture resistance, poor protection level, and have POE power management functions.
3. The service life is different
The service life of industrial exchanges is generally more than 10 years, while the service life of ordinary commercial switches is only 3 to 5 years. The difference in service life is related to the maintenance of the middle of the project. Therefore, generally speaking, it is in parks and office buildings. For video transmission in network surveillance environments such as parking lots and those environments where high-definition video output is required, industrial switches or switches whose performance needs to be comparable to those of industrial grade should be used.
4. Other reference indexes
The voltage used by industrial switches is different from that of ordinary switches. Industrial switches can be limited to DC48V, DC100V, AC220V, while ordinary switches can only work under AC220V voltage, and industrial switches are mostly in ring network mode, so the line is reduced accordingly. Use and maintenance costs.
Summary: Industrial switches need to use various industrial sites and are the most important electronic equipment in industrial networks. Well, the above is a detailed introduction about the difference between industrial switches and ordinary switches. I hope that everyone will have an understanding of industrial switches, and I hope to help friends in need.
