Industrial-grade 4-port USB 3.0 PCIe adapter with independent controllers and regulated power.
LR-LINK presents the LRSU9A72-4A, a specialized 4-port USB 3.0 host adapter engineered for demanding industrial and machine vision environments. Unlike standard adapters that share a single controller across multiple ports, this solution utilizes four independent NEC upD720202 controllers. This architecture ensures that each port delivers full 5 Gbps bandwidth independently, preventing performance bottlenecks during multi-device operations.
A key differentiator of this adapter is its robust power management system. It features an on-board 5V DC regulated power supply capable of delivering up to 2.8A @ 12V from the PCI Express bus. Users can configure current limits between 900mA and 1500mA per port, providing stable and reliable power to connected USB devices without requiring external power sources.
Designed for seamless integration, the LRSU9A72-4A connects via a PCI Express Gen2 x4 interface, offering a total bandwidth of 2GB/s. It supports Windows XP/7/8 and Linux operating systems and comes with both low-profile and full-height brackets for versatile chassis compatibility. With a wide operating temperature range of 0°C to 60°C, it is built to withstand harsh industrial conditions.
Four independent NEC controllers prevent bandwidth sharing, ensuring max speed per port.
On-board 5V DC supply with configurable current limits for stable device operation.
Wide temp range and robust design ideal for vision and industrial applications.
Delivers 5Gbps transfer speed per port via PCIe 2.0 x4 interface.
