The difference between industrial mainboard and commercial mainboard

The motherboard is an inseparable part of the computer. With the motherboard, the computer can operate normally.

However, because of the importance of the main board, the main board is divided into industrial main board and commercial main board.

The average price of most industrial mainboards on the market is higher than that of last month. Do you know the difference between them?

1. Size and specification: ATX architecture is mainly used for commercial motherboards at present; In order to adapt to various application environments,

The motherboard adopts various sizes and specifications, including ATX, Micro-ATX, LPX, POS and other specifications.

2. Support for expansion slots: Commercial motherboards often only provide 4 PCI slots,

Due to the restriction of PCI specification, the drive capacity of PCI 4 has a considerable attenuation, so most commercial motherboards only provide 3 PCI slots; Due to the industrial nature of its design materials, the support for PCI slots of industrial motherboards can easily achieve the support for five PCIs, and will not cause the attenuation of PCI drive capability. At the same time, it can support PCI-E devices with high bandwidth. With ISA slot, it can realize good support for industrial ISA low-speed acquisition card and data card. Embedded GPIO bus can realize GPI and GPO functions.

3. Components used: Due to the timeliness of the products pursued by the commercial motherboard and the market positioning of its own products, the selection of components generally only needs to meet the service life of 2 to 3 years of system operation;

The selection of industrial mainboard materials will select components that have been verified for a long time with high requirements to ensure the high reliability requirements of the product under harsh conditions.

For example, some solid-state capacitors and closed inductors that only appear in servers and high-end commercial mainboards are widely used in intelligent industrial control industrial mainboards;

4. Operating environment: industrial mainboard often works in harsh environment

(long working hours, bad weather, humidity, vibration, dust, radiation, high temperature, etc.),

Under these circumstances, the commercial mainboards are not competent. Most of the commercial mainboards can only operate in a stable environment (short working hours, indoor, normal temperature).

Although the industrial main board and the commercial main board seem very similar, the situation is quite different. You must observe carefully when selecting the motherboard. Each product needs different products in different environments and has its own advantages. If you choose home use, then you can use commercial motherboards.
