The Beckhoff CA PCIe Bus Adapter Series is a range of PCI Express communication adapters used to extend Beckhoff Industrial PCs with protocol-specific fieldbus and interface functions.
Depending on the model, the range includes options for networks and interfaces such as CANopen, PROFIBUS, CAN FD, Ethernet, RS232, USB, and related PC-side expansion functions. These adapters are intended to add connectivity directly at the PC level, with model-specific differences in channel count, connector format, transmission capability, and supported protocol features. Beckhoff offers both PCIe fieldbus cards and more compact PCIe module formats, so the product family is best understood as a modular expansion platform rather than a single uniform adapter design. The series is suited for machine and control systems that require PC-based integration of industrial communication networks and peripheral interfaces.
