In general, industrial control cabinets are computers specially designed for industrial sites, and industrial sites generally have strong vibrations, particularly dust, and high electromagnetic field interference. In general, factories operate continuously, that is, throughout the year. There is usually no rest. Therefore, the industrial computer must have the following characteristics compared with ordinary computers:

1) The chassis adopts steel structure, which has high anti-magnetic, dust-proof and shock-proof ability.

2) There is a dedicated backplane in the chassis, and there are PCI and ISA slots on the backplane.

3) There is a special power supply in the chassis, and the power supply has strong anti-interference ability.

4) The ability to work continuously for a long time is required.

5) Generally use standard chassis that is easy to install (4U standard chassis is more common)

Industrial computer has better stability than ordinary computer, such as ATM, industrial computer is often used.

Except for the above features, the rest is basically the same. In addition, due to the above professional characteristics, the price of the industrial computer of the same level is more expensive than that of the ordinary computer, but it is generally not too different.
