What is the difference between industrial grade switches and general switches?

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

2. Industrial Ethernet switches including mechanical environment adaptability, such as resistance to vibration and impact resistance, climate adaptability (work for - 20 ~ + 85 ℃ temperature requirement, at least for 10 ~ + 70 ℃, and corrosion resistance, dustproof, waterproof), electromagnetic environment adaptability, or electromagnetic compatibility EMC shall conform to EN 50081-2, EN 50082-2, EN 50082-3, EN 50082-4, the FCC standard, GB/T17626, IEC61000 etc.

3. Industrial Ethernet switch products should adapt to the harsh environment of industrial control site.The network equipment used in the industrial field must pass the surge test according to iec61000-4-5, GB/T17626.5 and other standards; the power frequency magnetic field immunity test according to iec61000-4-8, GB/T17626.8 and other standards; the pulse magnetic field immunity test according to iec61000-4-9, GB/T17626.9 and other standards; the voltage variation immunity test according to the standards iec61000-4-11 and GB/T17626.11.

4. Most industrial Ethernet switches are designed with wide voltage, operating voltage ranging from 18VDC to 36vdc, 220VA, 220VDC, 110VDC, etc.

5. The power supply of industrial Ethernet switches is generally designed as redundant double power supply, while that of civil Ethernet switches is single power supply.

6. Installation of industrial Ethernet switches: DIN rail, rack, etc.Installation mode of civil Ethernet switch: desktop and rack.

7. Industrial Ethernet switches working temperature wide working temperature (working temperature requirements - 20 ~ + 85 ℃, at least for 10 ~ + 70 ℃), narrow civil Ethernet switch operating temperature range.

8. Industrial Ethernet switch heat dissipation without fan housing, civil Ethernet switch fan heat dissipation.

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

11. Industrial Ethernet switch is fully enclosed and dustproof with good dustproof performance.

12. Industrial Ethernet switch link fault recovery time < 300ms.Civil Ethernet switch over 30 seconds.

      From the above indicators, it can be seen that civil switches are not up to the requirements of industrial environment. Therefore, in an increasing number of industrial automation fields, many users choose to use industrial Ethernet switches in order to ensure industrial security.

      The so-called industrial Ethernet generally means that it is technically compatible with commercial Ethernet (i.e. IEEE802.3 standard), but in product design, it can meet the needs of industrial site in terms of material selection, product strength, applicability, real-time, interoperability, reliability, anti-interference and essential safety.

      With the development and popularization of Internet technology, Ethernet technology has also developed rapidly. The improvement of Ethernet transmission rate and the development of Ethernet switching technology bring hope to solve the non-deterministic problem of Ethernet communication and make it possible to fully apply Ethernet in the field of industrial control.
