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!
