Frequently Asked Questions

Learn More About Industrial Expansion Cards

The key factors to check are the available expansion slot type on your host system (PCIe, PCI or PC/104), the number of available slots, the physical card length your chassis supports, and the operating system and driver compatibility for your application. Our team can help verify compatibility between a specific card and your host system before you order. Discuss your requirements with our Sales team today.

PCI is an older parallel bus standard still found in many legacy industrial systems, offering reliable compatibility with established hardware platforms. PCIe (PCI Express) is the modern successor, using a serial point-to-point architecture that delivers significantly higher bandwidth and lower latency, making it better suited to demanding applications such as high-speed data acquisition, 10GbE networking and machine vision frame grabbing. We stock both formats to support new system designs and legacy upgrade projects alike.

Yes. Alongside PCIe and PCI formats, we stock PC/104 expansion cards for compact and stackable embedded systems where standard full-size slots are not available. These are commonly used in rugged, space-constrained or legacy industrial platforms. If you are unsure which format is right for your system, speak to our engineers and we can advise based on your hardware.
