B&R X67BC8321.L12 X67 POWERLINK Bus Controller with 16 Digital Channels
Product Overview
The B&R X67BC8321.L12 is an IP67 POWERLINK bus controller for the B&R X67 distributed I/O system. It operates as a POWERLINK V1/V2 controlled node and integrates 16 digital channels that can be configured by software as inputs or outputs.
The controller also provides an X2X Link connection for local expansion and can supply up to 15 W to additional I/O modules. Its integrated POWERLINK hub and M12 connection system support efficient field-level network wiring on modular industrial machinery.

Compatible System and Applications
The X67BC8321.L12 connects X67 and other compatible X2X Link I/O nodes to a POWERLINK network. Typical applications include synchronized machine I/O, modular packaging lines, material-handling systems, robotic cells and distributed automation equipment.
Maintenance and Replacement Notes
Verify the complete .L12 model, POWERLINK network configuration, node assignment, firmware, Automation Studio project, digital channel mapping, connector coding and downstream X2X Link power load. A bus controller using another fieldbus is not a direct replacement.
Related Models
Other X67 bus controllers may support PROFIBUS, EtherNet/IP or different connector layouts. The network protocol, complete suffix, channel count and physical connections must all match the installed system.
Inquiry and Supply Notes
Provide the nameplate, POWERLINK topology, node settings, Automation Studio hardware tree, firmware information and connected X2X Link module list for an accurate compatibility review.
