Introduction
8 independent USB 3.2 Gen2x2 Type-C ports at up to 20Gbps each;
Based on ASMedia ASM3242 host controllers for stable multi-device performance;
PCIe Gen3 x16 bus with 8.0GT/s high-speed transmission and lossless full-bandwidth allocation;
PCIe 6Pin external power supply delivers up to 75W; each port provides 5V/1500mA.

When industrial systems require simultaneous high-speed connections to multiple USB devices, bandwidth conflicts and port density limitations often stall production lines. The LRSU9B20-8C expansion card solves this by providing eight independent USB 3.2 Gen2x2 Type-C ports, each controlling a dedicated ASM3242 chip to eliminate bottlenecks.

Operating on a PCIe 3.0 x16 bus with 8.0GT/s transmission, the card delivers full bandwidth efficiency. Each port supports up to 20Gbps data rate, with backward compatibility to 10Gbps, 5Gbps, and lower speeds. Total throughput is scalable to 160Gbps, enabling seamless parallel data transfer for multiple devices.

This adapter is designed for machine vision, factory automation, precision inspection, and logistics sorting. It supports Windows and Linux systems with plug-and-play functionality, ensuring stable long-term operation. For high-density industrial USB expansion, the LRSU9B20-8C offers reliable performance and effortless deployment.

I bought one first to test it. After running it for 7×24 hours, the heat control remained excellent. The plug-and-play feature works perfectly with my system. Since it passed the test, I plan to place a bulk order.
