ProfiHub B5 - 5 Channel PROFIBUS DP Repeater

 

 

One of our most popular products! The ProfiHub B5+ allows for almost any type of PROFIBUS network design - star, tree or linear. If you're considering inserting a spur/stub line, rather consider using a ProfiHub instead. It will mean a much more stable and reliable network. Each channel is electrically isolated which mean that each channel creates an entirely new PROFIBUS RS 485 segment. This also means that troublesome devices or segments can be isolated from the rest of the bus.

It's like having 5 repeaters in one device. Often one will find multiple standard repeaters in the same panel, but with 1m of cable between them trying to achieve a star topology, but the extra cabling gets messy and means more complexity and un-reliability. Remedy this with the ProfiHub! This concept is show in the image below right but with the ProfiHub A5 which is the IP67 variant.

 Other benefits include:

  • Hot slave insertion/removal during operation
  • Short circuit protection on each channel
  • Compact and robust construction
  • Screw terminals and DB9 connectors can be mixed
  • Conveniently arranged networks
  • Extendable installations
 
Best of all, this unit is really simple to use! Power it with 24V and connect your segments. If the channel is a start to a segment and you're screwing the cable in directly, then use the built in termination switch to absorb any reflections from the segment.  

ProfiHub B5+RD - PROFIBUS Hub with Diagnostic slave device

The ProfiHub B5+RD is identical as the regular ProfiHub B5 family with an additional integrated micro ProfiTrace diagnostic unit. The ProfiHub offers a PROFIBUS DP slave device to transfer bus statistics and device event information to the PLC/DCS system. Think of it as repeater providing diagnostics for 6 segments.   This innovative network component is an essential element when it comes down to maintaining PROFIBUS DP systems when the host system has to be involved. The application software was in past never able to identify bus diagnostic information and act accordingly. With the ProfiHub B5+RD this information is fully available. Even the location of certain devices behind the channels of the ProfiHub is very useful to identify the topology from a host system point of view.  
The user has to provide the ProfiHub with a software bus address (set slave address function). By means of the GSD file the user can configure the data that is required from the ProfiHub. The cyclical data can contain simple statistics up to complex structures identifying channel problems. The ProfiHub B5 is a solid network component providing reliable solutions for spur lines and star-shaped structures in PROFIBUS DP networks. Furthermore, it’s the first ProfiHub that has been provided with a built-in PROFIBUS DP slave for transferring diagnostic data to a host system.

ProfiHub A5 - 5 Channel PROFIBUS DP Repeater

The ProfiHub A5 is a multi-channel PROFIBUS DP repeater which allows you to create a more robust tree topology in an environment that requires a device to be IP 65 rated. Users of the A5 simply connect the master into the main incoming channel are able to branch off to other network segment via the other channels.
 

Each channel is electrically isolated so troublesome segments or devices can be isolated. The beverage industry uses this particular device as it is resilient to liquid leaks against which other repeaters simply wouldn't hold up. Other application areas include:

  • Branch lines to analyzers, flow meters and actuators 
  • Roof mounted devices in tank farms
  • Creating tree/star type topologies
  • Removable VSDs (variable speed drive) and soft starters 
  • Outdoor applications with device and cable stress
  • Humid and dusty environments
  • Barrier for non electrically-isolated equipment

ProfiHub B2+R

This ProfiHub is just  like the ProfiHub B5+R, but for when you only need to create 2 segments off the main PROFIBUS network! It makes for a very cost effective alternative for creating redundancy between two PROFIBUS cables or for creating branches inside MCCs where space is limited. 

ProfiHub B2FO2+ - PROFIBUS Fiber Optic Coupler

 

The ProfiHub B2FO2 is a cost effective solution to convert RS 485 copper segments to PROFIBUS fiber optic in a transparent manner. It enables reliable applications where long cable distances and isolation between devices and segments are required.
