Hubs, Repeaters and Terminators

Procentec Repeaters are widely accepted as one of the most reliable and lowest cost options for splitting DP networks into segments.

The well-known ProfiHub family is a collection of multi-channel PROFIBUS DP network components to create reliable star/tree networks and long multi-device branch lines. They are deployed in many applications worldwide and available in different varieties to comply with the requirements of the end-user.

Now ProfiSwitch is a new introduction to the range allowing different bit rates to be used on each segment.  ProfiSwitches are a real game changer allowing the bit rates to be optimised on each segment, with corresponding variable segment cable lengths. The clever feature is that the ProfiSwitches are transparent to all traffic, so switches do not need configuration and they allow all devices and diagnostics to be seen at the top level, even though lower segments are running at different speeds.  

All Repeaters, ProfiHubs and ProfiSwitches are equipped with total galvanic isolation. Behind each repeater a segment is created that is able to handle 31 devices with a cable length determined by the bit rate of that segment. Each repeater blocks short circuits and other bus problems. The ProfiSwitch is also able to customize the baudrate on each channel.

Examples of application areas

  • Dynamic spur lines to devices.
  • Star, tree and bus structured networks.
  • Pull/Plug motor control centers.
  • Barrier for non-isolated equipment.
  • EMC sensitive applications.
  • Applications with device and cable stress.
