The difference between industrial control motherboard and commercial motherboard

You may be a bit unfamiliar with the termsindustrial control motherboard and commercial motherboard, but for friends in the industrial and commercial electronics industry, they are very unfamiliar.The main feature of industrial motherboards is that they can operate for a longtime mainly based on low power consumption. The main characteristics ofcommercial motherboards are strong confidentiality requirements and embeddedsystems with high-strength firewalls. Of course, let's truly understand thedifferences between them below!

The difference between industrial controlmotherboards and commercial motherboards:

1. Commercial motherboards use ordinaryelectrolytic capacitors, mainly to reduce the cost of the motherboard

2. Industrial control motherboard components: The components of the motherboard need to adapt to a wide temperature environment (-20 ℃~60 ℃) to ensure normal operation in harsh environments (permanent startup within its lifespan, harsh weather, humidity, vibration, dust,radiation, high temperature, etc.); Mainboard components need to be resistant to high temperatures, moisture, and so on. High quality surface mountelectrolytic, tantalum, and ceramic capacitors

3. The PCB of industrial control motherboard: Commercial motherboards adopt a 4-layer PCB design. Generally, PCB circuit boards are divided into four layers, with the top and bottom two layers being the signal layer, and the middle two layers being the ground layer andpower layer. The ground layer and power layer are placed in the middle. The industrial motherboard adopts a PCB circuit board design with more than 6 layers, which is designed to enhance the motherboard's resistance to electromagnetic interference, electromagnetic compatibility, stability, and soon

4. CPU: Industrial control motherboards generally use low-power CPUs to adapt to the harsh environment of the industrial control industry. AtomN230 \ 270 \ 330 \ N450D525 is a CPU that integrates the functions of the north-south bridge into the processor

5. The ability to resist electromagnetic wave interference is different: the requirement for the ability to resist electromagnetic wave interference is high, and it needs to pass EMI, EMC andother tests and certifications. This needs to be considered from two aspects:one is from the design of the motherboard's circuit layout, and the other is from the selection and structure, power supply, and grounding situation

6. Supporting more interfaces: It can also support Mini PCI-E, PC 104+, multiple COM port interfaces, embedded GPIO bus,dual display function with LVDS, HDMI, DVI interfaces, and the full field card can be matched with the motherboard for more expandability, supporting multiple ISA, PCI, MINIPCI extensions.

7. Usage environment: Industrial controlmotherboards often operate in harsh environments with a temperature range of-20 ° C to 70 ° C (permanent boot, harsh weather, humidity, vibration, dust, radiation, high temperature,etc.), which commercial motherboards cannot handle.

8. Protection function: The industrial control motherboard is specially designed to automatically restart the watchdog and prevent surge impact in case of abnormal situations such as crashes, fully ensuring the high stability requirements of the system in harsh environments.
