3 Segment redundant PROFIBUS DP Repeater

The ProfiHub B2+ enables wide-ranging RS 485 star/tree/bus segments and long spur lines for PROFIBUS DP installations in IP 20 environments.

It is a straightforward and robust network component made to design flexible and object-oriented networks. When redundancy is enabled, the ProfiHub B2+ is transformed into an extremely reliable and cost-saving redundant repeater solution.

PROFIBUS DP Repeater with 3 Segments

The ProfiHub B2+R is equipped with two galvanically isolated transparent repeaters (offering three segments). Each segment can handle 31 devices and a cable length equal to the main bus. To save costs on plugs and to offer flexibility, the repeater contains screw terminals as well as DB9 connectors. Termination for each segment is on-board and switchable.

If bus redundancy is enabled, two segments will form a redundant pair that is completely compatible with the ABB RLM01. An alarm contact is linked to events based on the status of the power supply and the bus redundancy status.
