PCIe 2.0 x4 adapter adding four USB 3.2 Gen1 Type-A ports for industrial and server use.
Connecting multiple high-speed peripherals like industrial cameras often exhausts limited motherboard USB headers, creating bottlenecks in machine vision setups. The LRSU9A11-4A(3U) PCIe USB adapter resolves this by expanding connectivity without occupying valuable external hubs.
Built on the Fresco Logic FL1100EX controller, this card provides four USB 3.2 Gen1 Type-A ports, each delivering up to 5Gbps single-channel bandwidth. This ensures stable, high-throughput data transfer for demanding applications, while maintaining backward compatibility with USB 2.0 devices for legacy support.
Ideal for industrial automation, server expansions, and machine vision systems, this adapter supports hot-plugging for flexible device management. Its robust ESD protection and wide OS compatibility, including Windows Server and Linux distributions, make it a reliable choice for professional data transmission environments.
Provides four USB 3.2 Gen1 Type-A ports with up to 5Gbps single-channel bandwidth for fast data transfer.
Based on Fresco Logic FL1100EX main control chip, ensuring stable performance and compatibility.
Features ESD protection (±8KV contact, ±4KV air) and operates in temperatures from 0℃ to 85℃.
Supports PCIe 2.0 x4 interface, compatible with x8/x16 slots, and works with Windows, Linux, and VMware.
