ProfiHub B2FO2+  PROFIBUS Fiber Optic Coupler

0232The ProfiHub B2FO2 is an economic solution to convert PROFIBUS fiber optic to RS 485 copper segments and vice versa. It enables reliable applications where long cable distances and isolation between devices and segments are required.

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 to benefit from the advantages 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 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.
