PROFIBUS Repeater & Hub with Redundancy - ProfiHub B5+R
The ProfiHub B5+R is a DIN rail mount PROFIBUS multi-channel repeater with five (5) galvanically isolated channels, in an IP20 enclosure. The B5+R supports Redundant PROFIBUS Channels. Create star or tree-shaped networks or isolate a problem device on its own segment. Up to 31 devices can be connected per channel (segment). The B5+R also eliminates the need for spur lines, which are often sources of network problems in PROFIBUS DP networks. Standard repeaters provide one new segment, but with the ProfiHub B5+R, 5 new segments are created. Combined with the main or backbone channel, there are total of 5+1 = 6 segments connected to the B5+R. Highly segmented PROFIBUS networks are more reliable since problems with individual devices stay within the segment and the galvanic isolation prevents the propagation of disturbances to the rest of the network. The ProfiHub is often used for Motor Control Centers (MCCs) to help isolate each “bucket” from the next. MCCs are notorious for in
