General Description

The PROFIBUS DP B1 Repeater tackles the technical limitations of existing PROFIBUS repeaters. It does not have the frustrating short-circuit bug and the data is constantly monitored for glitches which are digitally filtered out. It has the following unique features:

  • Guarantees conveniently arranged networks
  • Compact design
  • Cost-saving

About the compact PROFIBUS repeater

The advanced 12 Mbps core of the B1 is comparable to the ProfiHub: it can be cascaded without limitations and has increased RS 485 strength. Furthermore, every channel has on-board switchable termination and is able to drive 31 devices. The removable screw terminals of the PROFIBUS interface are pinned-out in a way that reversed mounting of the repeater does not impact existing wiring. A DB9 connector is provided to connect diagnostic tools. The redundant power supply increases the reliability of the application.

This compact and easy to use network component complies with the requirements of the demanding modern industry to increase the PROFIBUS cable length and amount of connected devices.
