A comprehensive analysis of USB interfaces in the industrial control field
In the field of computer peripheral connectivity, USB (Universal Serial Bus) has undoubtedly been a revolution. It solved the problems of the early 1990s, such as the multitude of peripheral interface types (such as PS/2, serial ports, parallel ports, SCSI, etc.), complex configuration, slow speed, and lack of hot-swapping capabilities. Since the birth of USB 1.0 in 1996, this unified interface standard, which first introduced the concept of hot-swapping, has continuously evolved and improved in speed, becoming an indispensable connection method in industrial control and many other fields served by Lingchen Technology. This article will focus on the industrial control industry, detailing key USB knowledge to help you better utilize Lingchen Technology's products and solutions.

Industrial Control USB Speed Test Results
Lingchen Technology's tests show that mainstream industrial control standards (USB2.0/USB3.2 GEN1/GEN2x1) can reach 70%-90% of their theoretical speeds: USB2.0: 60MB/s → Basic peripherals such as keyboards/mice; USB3.2 GEN1: 500MB/s → Medium-speed data acquisition; USB3.2 GEN2x1: 1212MB/s → High-speed storage devices
Redriver: The Key to Stable High-Speed Signals
In industrial control equipment, USB signals are prone to attenuation due to long PCB traces (especially USB3.2 and above). Lingchen Technology enhances driving capability by integrating Redriver chips to ensure signal integrity in industrial environments.
Interface Selection Guide (Industrial Control Focus)
Main Interface Type-A: USB2.0: 4-pin/black and white → Compatible with older devices; USB3.0: 9-pin/blue → Mainstream industrial control peripherals.
Future Trend: Type-C:
24-pin reversible connector / full-duplex two sets of ultra-high-speed signals supporting Alternate Mode (such as video transmission)
Lingchen Technology's new generation industrial PCs have integrated Type-C interfaces to meet expansion needs.
Power Supply Capability Evolution
Type-A: USB 3.0 reaches 7.5W (BC1.2) → Driving external optical drives Type-C + PD protocol: 100W-240W → Powering high-power devices
Lingchen industrial control equipment provides stable power output to ensure the continuous operation of peripherals.
