Profibus Hub & Repeater
ProfiHub A5 (IP65)

DESCRIPTION:
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. There is also an IP 20 version available, the ProfiHub B5. 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.

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!
