Anybus ProfiHub B4FOR+ (Multi-Mode)

Anybus ProfiHub B4FOR+ (Multi-Mode) is a cost-effective solution for connecting PROFIBUS fiber optic networks to multiple RS 485 segments, and vice versa. It enables ring topologies and redundant network expansion, even over long distances.

The fiber optic channel is split into two ports. This creates additional redundancy in the ring and strengthens the network backbone. The four RS 485 channels are galvanically isolated and prevent the interruptions typical of daisy-chained networks.

Why use it

ProfiHub B4FOR+ is ideal for:

• connecting RS 485 segments to a fiber optic backbone;
• extending PROFIBUS networks over long distances;
• building redundant ring topologies;
• strengthening the network backbone;
• galvanically isolating network segments;
• avoiding network interruptions caused by daisy-chain connections.
