Product Information

Product Description

Authorized North America Distributor Stamp

The ProfiHub A5 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 65 applications.   The days of one long daisy chain installation are over!    With the ProfiHub A5, a whole new way of designing PROFIBUS DP Networks is possible.  

Wiring diagram. Each spir line can be 200m at 1.5Mbps. WIring problems do not spread to other spur lines.

With 5 Galvanic isolated channels (segments) and each channel capable of handling up to 31 devices, each ProfiHub A5 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!


  • Each channel complies to the DP - RS 485 specifications
  • Each channel has status and error display
  • Integrated termination facility for each channel and main bus
  • Hot slave insertion and removal during operation
  • Grounding concept is configurable
  • Standard glands can be replaced with M12
  • Suitable for all DP cables
