ProfiHub B4FO2+ – Fiber Optic to Multi Segment Coupler
Previous product Next product

ProfiHub B4FO2+The ProfiHub B4FO2 is a cost-effective solution to link PROFIBUS fiber optic to multiple RS 485 segments and vice versa. It enables reliable applications where long cable distances and an isolation between devices and segments are required. The massed junction of copper segments reduce expensive fiber optic couplers and create an object oriented overview for the end user.

The B4FO2 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 B4FO2 is equipped with 4 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.
