ProfiHub A5 is a robust network component for PROFIBUS DP installations. It enables long multi-device spur lines and backbone structures with star/tree segments in IP 65 applications.


PROFIBUS DP is a high-speed communication bus that has to comply with strict rules concerning spur lines and star networks. The ProfiHub A5 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 A5 has the same functionality as the ProfiHub B5.

Create reliable, flexible and object oriented DP installations using the ProfiHub A5.

The ProfiHub A5 is essential to obtain better control during maintenance and upgrading of the network.

In order to install the ProfiHub A5 in areas without the need for a separate 24 VDC power supply, this unit is equipped with an integrated 110/230 VAC power supply.
