Introduction to the difference between industrial Ethernet switches and commercial switches


Industrial switches are also called industrial Ethernet switches. Specifically designed to meet the needs of flexible industrial applications, it has carrier-grade performance characteristics and can withstand harsh working environments. The product series is rich, the port configuration is flexible, the wide temperature design is adopted, the protection level is not lower than IP30, and the standard and private ring network redundancy protocols are supported. And ordinary commercial switches are far inferior to industrial switches in performance and adaptable environment.

1. Compared with commercial Ethernet switches, industrial Ethernet switches can meet the needs of industrial sites in terms of design and selection of components, product strength and applicability.

2. Industrial Ethernet switches include mechanical environment adaptability (such as vibration resistance, shock resistance), climatic environment adaptability (working temperature requirements are -40~+85℃, at least -40~+70℃, and corrosion resistance, Dustproof, waterproof), electromagnetic environment adaptability or electromagnetic compatibility EMC should 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 the industrial control site. The use of network equipment in the industrial field must pass the surge test of IEC61000-4-5, GB/T17626, 5 and other standards, and the power frequency magnetic field immunity test by IEC61000-4-8, GB/T17626, 8 and other standards. IEC61000-4-9, GB/T17626, 9 and other standards are used for pulse magnetic field immunity test, and voltage variation immunity test can be carried out according to standard IEC61000-4-11, GB/T17626, 11, etc.

4. Most of the industrial Ethernet switches are designed with wide voltage, and the working voltage is 12VDC ~ 48VDC, 220VAC, 220VDC, 110VDC, etc.

5. The power supply of industrial Ethernet switches is generally designed with redundant dual power supplies, and commercial Ethernet switches are single power supply.

6. Industrial Ethernet switch installation method: DIN rail, rack, etc. Commercial Ethernet switches are installed in desktop and rack.

7. The working temperature of industrial Ethernet switches is wide (the working temperature is required to be -40~+85°C, at least -40~+70°C), and the working temperature range of civil Ethernet switches is narrow, generally 0~+50°C.

8. The cooling method of industrial Ethernet switches has no fan shell for cooling, while civil Ethernet switches are fan-cooled.

9. Electromagnetic compatibility EN50081-2 (EMC, industry) EN50081-2 (EMC, office) EN50082-2 (EMC, industry) EN50082-2 (EMC, office). Industrial Ethernet switches meet EN50082-2 (EMC, industry).

10. Industrial Ethernet switch shell material Alloy shell, high strength plastic shell, low strength.

11. The dustproof fully enclosed structure of the industrial Ethernet switch has better dustproof performance.

12. The link failure recovery time of the industrial Ethernet switch is less than 20ms. More than 5 seconds for commercial Ethernet switches.

From the above indicators, commercial switches are difficult to meet the needs of industrial environments. Therefore, in more and more industrial automation fields, many users choose to use industrial Ethernet switches to ensure industrial security.
