Product Information

Product Description


Direct replacement is the ProfiHub B5+R.


Authorized North America Distributor Stamp

The ProfiHub B5 is an advanced, flexible and robust network component for PROFIBUS DP installations, providing the unique capability to implement long multi-device spur lines and backbone structures with star/tree segments in IP 20 applications.  

With 5 Galvanic isolated channels (segments) and each channel capable of handling up to 31 devices, each ProfiHub B5 can accommodate a maximum of 155 devices.  With no limit in serial placement or cascading of ProfiHubs, you can arrange your network to meet your needs and budget.   

Because the ProfiHub creates isolated segments, the slave devices can now be removed and added during operation!  Also electrical bus problems and EMC disturbances in a segment do not spread to the other segments. The intelligent logic and isolation circuits of the ProfiHub do not change the bit width. This also means there is no limit to how many ProfiHubs are connected in series!


  • DP - RS 485 specifications for each channel
  • No limit in serial placement or cascading of ProfiHubs
  • Integrated Ground Rail with configurable grounding system (direct or capacitive)
  • Screw terminals and DB9 connectors. (can be mixed)
  • Each channel has status and error display
  • Each channel has short circuit protection
  • Hot slave insertion and removal during operation
  • Conveniently arranged networks
  • Easy extendable installations
  • Suitable for all DP cables
