ProfiHub B5 - 5 Channel PROFIBUS DP Repeater


profihubB5ProfiHub B5 is an easy and robust network component for PROFIBUS DP installations. It enables long multi-device spur lines and backbone structures with star/tree segments in IP 20 applications.

PROFIBUS DP is a high-speed communication bus that has to comply with strict rules concerning spur lines and star networks. The ProfiHub B5 is a perfect economic solution to create reliable start networks in RS 485 DP networks.

It has the functionality of 5 galvanic isolated transparent repeaters. This allows network structures with extended spur lines that individually can handle a maximum of 31 devices and a length equal to the main bus.
The ProfiHub B5 has the same functionality as the ProfiHub A5 (IP 65).


Create reliable, flexible and object oriented DP
installations using the ProfiHub B5.


The ProfiHub B5 is essential to obtain better control
during maintenance and upgrading of the network.
