The ProfiHub B5+R is an advanced, flexible and robust network component for PROFIBUS DP installations. It has the unique capability to implement long multi-device spur lines and backbone structures with star/tree segments in IP 20 applications. A new additional feature is the integrated micro ProfiTrace diagnostic unit.


  • Redundant power supply input
  • Redundancy option for 2 channels
  • Alarm contact related to the redundant power supply and channels

5 Galvanic isolated channels (segments)

  • each channel capable of handling up to 31 devices
  • accommodate a maximum of 155 devices
  • no limit in serial placement or cascading of ProfiHubs
  • arrange your network to meet your needs and budget

ProfiHub B5+R creates isolated segments

  • slave devices can now be removed and added during operation
  • electrical bus problems and EMC disturbances in a segment do not spread to the other segments
  • intelligent logic and isolation circuits of the ProfiHub do not change the bit width
  • no limit to how many ProfiHubs are connected in series

Other benefits include:

  • Short circuit protection on each channel
  • Compact and robust construction
  • Screw terminals and DB9 connectors can be mixed
  • Conveniently arranged networks
  • Extendable installations
  • Cost savings through reduced installation complexity

  • 5 Isolated Channels
  • 31 Devices per channel
  • DP - RS 485 specifications for each channel
  • Each channel has status and error display
  • Each channel has short circuit protection
  • Max 1200 m spur line length (depends on baudrate)
  • Configurable grounding system
  • Integrated termination facilities
  • Bus redundancy option in Hub mode
  • IP 20 classification
Baud rate 9.6 Kbps to 12 Mbps (automatic detection)
Cable length 1200 m spur line length (depends on transmission speed)
