Product Overview

Connecting multiple high-speed industrial cameras or external drives often exhausts limited motherboard USB headers, causing bandwidth bottlenecks and connectivity issues in automated systems. The LRSU9A72-4A(3U) PCIe USB adapter resolves this by providing four dedicated high-speed ports through a single expansion slot.

Built on the Renesas uPD720202 controller, this card delivers up to 5Gb/s per channel bandwidth via its PCIe 2.0 x4 interface. This ensures consistent data throughput for demanding applications, while backward compatibility with USB 2.0 allows seamless integration with legacy peripherals without sacrificing modern speed requirements.

Ideal for machine vision, industrial automation, and server environments, this adapter supports hot-swappable devices with independent power stability. Its robust design handles diverse operating systems from Windows to Linux, making it a reliable choice for expanding I/O capacity in data centers and edge computing nodes.
