ProfiHub B5+R – 5 Channel PROFIBUS DP Repeater
Previous product Next product

PROFIHub B5-5The ProfiHub B5+ enables wide-ranging RS 485 star/tree segments and long spur lines for PROFIBUS DP installations in IP 20 environments. It’s an easy and robust network component to design reliable, flexible and object oriented networks.

PROFIBUS DP is a high-speed industrial bus that has to comply with strict rules concerning spur lines. The ProfiHub B5+ is a perfect economic solution to bridge user’s requirements and create reliable star networks. It’s an essential component to obtain better control during maintenance and upgrading of the network.

The ProfiHub B5+ is equipped with 5 galvanic isolated transparent repeaters (offering 6 segments). Each segment can handle 31 devices and a cable length equal to the main bus. To save costs on plugs and offer flexibility, it contains screw terminals as well as DB9 connectors. The DB9 connectors are also perfect measurement points for ProfiTrace to quickly measure all segments. Termination for each segment is on-board and switchable.

If bus redundancy is enabled, 2 segments will form a redundant pair. This creates an even more reliable network. An alarm contact is linked to events based on the status of the power supply and the bus redundancy if this is enabled.

Application areas 

  • Dynamic spur lines to devices
  • Star, tree and bus structured networks
  • Removable drives and motorsPull/Plug motor control centers
  • EMC sensitive applicationsBarrier for non galvanic isolated equipment
