Function and Positioning

As a core I/O expansion controller in the B&R 2005 system, the 3EX350.6 serves as a local master to manage up to 4 extended I/O backplanes, offloading I/O processing tasks from the main CPU (CP260, CP3xx, IF260, IP161). It enables seamless integration of additional digital/analog I/O modules, supporting real-time data acquisition and control signal transmission. LED indicators provide quick status monitoring, while its plug-in design simplifies installation and maintenance. It is ideal for building scalable, distributed automation architectures.
