The ProfiHub B5+R is an easy and robust network component to design reliable, flexible and object oriented networks. It allows wide-ranging star/tree segments and long spur lines for PROFIBUS DP installations in IP 20 environments. The ProfiHub B5 is essential to obtain better control during maintenance and upgrading of the network. The use ProfiHub results in lower operational costs and the optimization of the entire production process.

The ProfiHub B5+R is a perfect economic solution to bridge user’s requirements and creates reliable star networks in RS 485 networks. 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. If bus redundancy is enabled, two 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.
