Description

ProfiHub B2FO2+ – Fiber Optic to Segment Coupler

The B2FO2+ supports multiple fiber optic topologies; point-to-point, bus and star. The protocol transparency without configuration allows direct integration in existing PROFIBUS networks. This way, you benefit from the advantages that optical data infrastructures offer.

The ProfiHub B2FO2+ is equipped with 2 galvanic isolated RS 485 channels utilizing a maximum of 31 devices per channel.

The mechanical design consists of a compact, flat and stable metal housing which can be mounted on a DIN-rail. It contains an alarm relay, redundant power supply, diagnostic LEDs and it supports the redundancy feature.
