The Beckhoff LC Bus Couplers series is built for compact, lower-cost connection of Bus Terminals to industrial fieldbus networks while supporting distributed I/O expansion.
Across the series, these couplers support digital and, on certain models, analog signal handling, with capacities that vary by version and communication protocol. The units are designed with integrated status and diagnostic LEDs that indicate fieldbus state, terminal status, supply conditions, and error conditions to simplify commissioning and troubleshooting. Configuration can be carried out through software or the controller depending on the model, and the series supports common industrial communication behaviors such as cyclic data exchange, polling, and status-based messaging. Overall, the LC Bus Couplers are intended for space-conscious automation systems that need terminal-level connectivity, diagnostic visibility, and straightforward integration with Beckhoff Bus Terminals.
