Industrial control motherboards are motherboards used in industrial applications. They are used by industrial computers and can adapt to wide temperature environments, harsh environments, and long-term high-load work according to requirements. The working temperature range can reach -40 degrees -85 degrees, the working humidity range can reach non-condensing 0-95%, environmental dust, metal dust, ordinary dust, according to the structure and size of the motherboard can be divided into: full-length card, half-length card , 5.25 inches, 3.5 inches, PC104 architecture, etc. According to the selected chip series: 386, 486, 586, PIII, P4, ATOM, etc. Divided by chip type: X86 architecture, MIPS architecture, ARM architecture, etc. There are also some parts customized according to customer needs.
The main differences are reflected in the design features, platform options, interface design, use environment, etc.
Industrial control motherboard components are generally different from commercial materials, and need to consider the requirements of industrial occasions such as high temperature resistance and moisture resistance. In order to strengthen the EMC/EMI performance of the motherboard, enhance the stability of the motherboard. Industrial motherboards are designed with 6-layer and above PCB circuit boards.
Compared to ordinary motherboards, industrial motherboards generally use low-power chipsets to save energy and improve environmental adaptability.
Common platforms range from Intel Core, Nehalem to Sandybridge/Ivybridge, which was launched in 2012, and ATOM cedar-trail Atom platform, AMD's LX series (LX800) to Fusion, etc.
Secondly, the interface design is also different from ordinary motherboards. Due to the special use occasions of industrial control motherboards, the design interface will be customized according to the use occasion or a large number of standard interfaces will be stacked to adapt to various interfaces.
Common interfaces include serial ports, USB, LAN, LPT, etc. In order to adapt to the environment, they are generally equipped with anti-surge and anti-static designs.
Expansion interfaces include PC104 family, PCI-E family, PCI family, etc., in conjunction with industrial motherboards, the backplane supports multiple expansions.
At the same time with multiple display functions such as VGA, LVDS, HDMI, DVI interface, etc.
In addition, through special design, industrial control motherboards can automatically restart the watchdog when encountering abnormal conditions such as crashes to ensure the high stability of the system in harsh environments, which is much more stable than ordinary motherboards.
The use environment of industrial control motherboards is wider and harsher than ordinary computers. The typical environment of industrial control motherboards, working temperature: range up to -40 degrees-85 degrees, working humidity: range up to non-condensing 0-95%, environmental dust : Metal dust, ordinary dust, electromagnetic radiation: strong electromagnetic interference environment, self-radiation control, long-term work: permanent power on during normal life. Under these circumstances, ordinary motherboards are not competent.
