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

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

2. Industrial Ethernet switch includes mechanical environment adaptability (such as vibration resistance and impact resistance), climate environment adaptability (the working temperature is required to be - 20 ~ + 85 ℃, at least - 10 ~ + 70 ℃, corrosion resistance, dust prevention and 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 shall adapt to the harsh environment of industrial control site. The use of network equipment in industrial site must pass iec61000-4-5 and GB / T17626 5 and other standards, and passed iec61000-4-8 and GB / T17626 8 and other standards, and passed iec61000-4-9 and GB / T17626 9 and other standards, which can be tested according to iec61000-4-11 and GB / T17626 11, etc.

4. Most industrial Ethernet switches are designed with wide voltage, with working voltage of 18vdc ~ 36VDC, 220VA, 220VDC, 110VDC, etc.

5. The power supply of industrial Ethernet switch is generally redundant dual power supply design, and the civil Ethernet switch is single power supply.

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

7. The working temperature of industrial Ethernet switch is wide (the working temperature is required to be - 20 ~ + 85 ℃, at least - 10 ~ + 70 ℃), and the working temperature range of civil Ethernet switch is narrow.

8. The heat dissipation mode of industrial Ethernet switch is no fan shell heat dissipation, and that of civil Ethernet switch is fan heat dissipation.

9. Electromagnetic compatibility en50081-2 (EMC, industry) en50081-2 (EMC, office) en50082-2 (EMC, industry) en50082-2 (EMC, office). Industrial Ethernet switch meets en50082-2 (EMC, industrial).

10. The shell material of industrial Ethernet switch is alloy shell with high strength and plastic shell with low strength.

11. The industrial Ethernet switch has a fully enclosed structure with good dust resistance.

12. The link fault recovery time of industrial Ethernet switch is less than 300ms. Civil Ethernet switch for more than 30 seconds.

From the above indicators, civil switches are not competent for the needs of industrial environment. Therefore, in more and more industrial automation fields, many users choose to use industrial Ethernet switches in order to ensure industrial safety.

Generally speaking, industrial Ethernet 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 intrinsic 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 uncertain problem of Ethernet communication, and make it possible for Ethernet to be fully applied to the field of industrial control.
