XMC, PCI Express or VPX bus carrier cards for AcroPack® modules. The AcroPack product line updates our popular Industry Pack I/O modules with a PCIe interface format. This tech-refresh design offers a compact size, low-cost I/O, the same functionality and memory map of the existing Industry Pack modules and a rugged form factor. The AcroPack carriers come equipped with up to four AcroPack or mini-PCIe mezzanine module slots to offer maximum I/O density in VPX, XMC and PCI Express based systems. AcroPack carriers offer a unique secure plug-in connection to the I/O boards eliminating the customary flimsy cable connection.
