Small PCIE to 19PIN USB3.0 Expansion Card Key benefits Adds USB 3.0 capability to systems with a small PCIE port, expanding internal USB connectivity for peripherals in industrial environments. Compact form factor suited for industrial control motherboards and embedded systems with limited PCIe space. Simple, plugin operation that follows PCIe standard; the card must be plugged in to work. Compatibility and usage Suitable for industrial control motherboards with a small PCIE port. It is a small PCIE to 19PIN USB3.0 expansion card, designed to provide an internal USB 3.0 header connection. Important notes Note: It can only be used with PCIe standard. It must be plugged in to work when in use. Note: When plugging and unplugging the power cord from the floppy drives power socket, first lift the socket upward to disconnecting button on the cord from the adapter card, and then unplug it. Installation considerations Install by inserting into a PCIe slot and connecting to the 19pin USB3.0 header on the motherboard or expansion board. Ensure the power connector procedure described in the notes is followed to avoid damage to the adapter or cords. Use scenarios Industrial control systems requiring USB 3.0 connectivity on compact controller boards or automation panels. Small form factor or embedded PC builds where internal USB 3.0 headers are needed but space is limited. Upgrading legacy machines that lack USB 3.0 internal headers but have a suitable PCIe slot for expansion.
