The Acromag APC8620A is a non-intelligent PCI bus carrier card that interfaces Industry Pack (IP) modules with PCI bus systems in PC-based computers. It enables modular I/O assembly through five configurable IP module slots, supporting either five single-size modules or two double-size and one single-size module. A single populated carrier replaces multiple dedicated function PCI boards, delivering cost-effective custom I/O configurations with analog input/output, digital input/output, and serial I/O functions.
