Nowadays, more and more engineers understand that industrial Ethernet Switches are different from civilian Ethernet switches, and in most respects, they understand the differences, but detailed and systematic materials have not been seen. The following only summarizes the differences between some industrial Ethernet switches and civilian Ethernet switches that have been summarized so far, for reference only.
1. Industrial Ethernet switches Compared with residential Ethernet switches, Industrial Ethernet Switch products can meet the needs of industrial sites in terms of design and selection of components.
2. Industrial Ethernet switches include mechanical environment adaptability (such as vibration resistance, impact resistance), climatic environment adaptability (operating temperature requirements are -20 ~ +85 ° C, at least -10 ~ +70 ° C, and corrosion resistance, Dustproof, waterproof, electromagnetic environment adaptability or electromagnetic compatibility EMC shall comply with EN 50081-2, EN 50082-2, EN 50082-3, EN 50082-4, FCC, GB/T17626, IEC61000 and other standards.
3. Industrial Ethernet switch products should adapt to the harsh environment of industrial control sites. The network equipment used in the industrial field must pass the IEC61000-4-5, GB/T17626.5 and other standards for surge testing, and the power frequency magnetic field immunity test is passed through IEC61000-4-8, GB/T17626.8 and other standards. IEC61000-4-9, GB/T17626.9 and other standards for pulse magnetic field immunity test, voltage change immunity test according to standard IEC61000-4-11, GB/T17626.11.
4. Industrial Ethernet switches are mostly wide voltage design, working voltages of 18VDC ~ 36 VDC, 220VA, 220VDC, 110VDC and so on.
5. The industrial Ethernet switch power supply is generally designed for redundant dual power supply, and the civilian Ethernet switch is a single power supply.
6. Industrial Ethernet switch installation methods DIN rail, rack, etc. Civil Ethernet switch installation method desktop, rack.
7. Industrial Ethernet switch operating temperature is wide (working temperature is -20 ~ +85 ° C, at least -10 ~ +70 ° C), civil Ethernet switch operating temperature range is narrow.
8. Industrial Ethernet switch cooling mode Fanless case heat dissipation, civil Ethernet switch fan cooling.
9. Electromagnetic compatibility EN50081-2 (EMC, industrial) EN50081-2 (EMC, office) EN50082-2 (EMC, industrial) EN50082-2 (EMC, office). Industrial Ethernet switches meet EN50082-2 (EMC, Industrial).
10. Industrial Ethernet switch shell material alloy shell, high strength plastic shell, low strength.
11. Industrial Ethernet switches are dust-proof and fully enclosed, and have good dustproofness.
12. Industrial Ethernet switch link failure recovery time <300ms. Civil Ethernet switch for more than 30 seconds.
From the above indicators, it is difficult for civil switches to meet the needs of industrial environment. Therefore, in more and more industrial automation fields, many users have ensured industrial safety and chose to use industrial Ethernet switches.
