Industrial control motherboards with a small PCIe port provide compact PCIe expansion for industrial systems. Key features and benefits Small PCIe port enables PCIe connectivity in spaceconstrained industrial control environments. Compatible with PCIe standard devices, expanding functionality without replacing existing boards. Builtin whitelist hardware mechanism for controlled access. Flexible power options via small power inputs: supports small PCIe 15PIN power connectors or small 4PIN power supplies for floppystyle devices. Reliable and compact design optimized for industrial applications, with a focus on compatibility and straightforward operation. Compatibility and requirements Use only with PCIe standard devices; operation requires the proper PCIe connection to function. Designed for industrial control motherboards that incorporate a small PCIe port. Power delivery can be provided through a small PCIe 15PIN connector or a small 4PIN power supply used for floppy drives. Power and size considerations Small form factor suitable for tight installations in industrial cabinets and embedded systems. Power input options include a small PCIe 15PIN connector or a small 4PIN floppystyle power supply. Use scenarios Industrial automation: expands PCIe capabilities in compact control cabinets, enabling additional PCIebased controllers or interface cards without enlarging the system. Securityconscious environments: leverages the brand's whitelist hardware mechanism to control USB access. Embedded or smallformfactor systems: fits in compact embedded controllers or small PCs that require PCIe expansion with flexible power options. Note This product emphasizes function, compatibility, size, and security features while maintaining a professional and trustworthy tone. It does not introduce specifications beyond the described PCIe compatibility, whitelist mechanism, and power options.
