Product Description:

The X67BC8321.L12 is an industrial I/O node produced by B & R Automation for the X67 Analog Input Output Modules series. Housed in a compact form that mounts directly on machinery, the unit concentrates discrete sensing and actuation near the process and relays the data over its integrated POWERLINK network connection. By decentralizing sixteen digital channels and packaging power distribution with communication, the module simplifies wiring and shortens response paths in automated production lines.

The module supplies sensors and actuators with 24 VDC and permits each output to deliver up to 0.5 A. Field devices are attached through sealed M12 connectors, and the configurable input filter allows signal debouncing without external circuitry. Network traffic is carried on an Ethernet link that conforms to the 100 Base-T standard, while real-time synchronization is handled through a minimum POWERLINK cycle time of 400 µs. Two on-board event counters operate at up to 50 kHz, letting high-speed encoders or flow sensors be evaluated locally. Sixteen digital I/O points and one dedicated POWERLINK interface are supervised so that diagnostic flags are forwarded instantly to the controller.

Plant-wide integration is supported by a cable reach of 100 m between nodes and by a segment capacity of 60 X2X stations, giving flexibility in line layout. At the physical layer, the device transmits user data at 100 MBit/s, and it allocates 256 bytes of deterministic process data per cycle. The maximum synchronous payload is 256 bytes, while an additional 138 bytes are available for asynchronous messaging. A 15 W X2X link supply energizes the electronics so that only a single fieldbus cordset is needed for both power and communication, keeping installation straightforward.
