Thanks to the free choice of bus coupler, the Inline I/O system can be integrated into all common fieldbus systems and Ethernet networks. Depending on the bus coupler, you can connect up to 63 I/O terminals (up to 16 PCP devices).

Your advantages

  • Maximum flexibility in your station structure thanks to compatibility with all common bus systems and network protocols
  • Save space in the control cabinet thanks to the compact design of the new BK housing
  • Cost-effective station configuration thanks to a selection of bus couplers with integrated I/Os for machines and systems with a small number of signals

Variety of network connections

The Inline bus couplers are the link between the Inline system and the higher-level network. Bus couplers are available for the following communication protocols:
