Hubs, Repeaters and Terminators

profihub1

PROCENTEC is well-known for providing the best and most cost effective repeaters idea for splitting PROFIBUS DP networks.

The well-known ProfiHub family is a collection of multi-channel PROFIBUS DP network components to create reliable flexible star/tree networks and long multi-device spur lines. They are essential to obtain better control during maintenance and upgrading of the network. The use of ProfiHub results in lower operational costs and the optimization of the entire production process.

One new innovation is the ProfiSwitch which lets each segment have a different baud rate. This is a real game changer since it allows each segment to be optimized to the best baud rate. Idea for combining DP/PA Couplers, radio modem, or other slower DP devices or long wire runs.  ProfiSwitches are transparent to all traffic, so switches do not need to be configured. All devices and diagnostics are seen at the top level, even with the baud rate differences.

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

  • Create spur lines to devices.
  • Star, tree and bus structured networks.
  • Adding to legacy systems with Baudrate limitations
  • Couple PA and Wireless within one network
  • Barrier for non-isolated equipment.
  • EMC sensitive applications.
  • Applications with device and cable stress.
