ProfiHub B2FO2+
The ProfiHub B4FO2+ is a cost-effective solution to link PROFIBUS fiber optic to RS 485 segments and vice versa. It enables reliable applications where long cable distances and an isolation between devices and segments are required. It has the following unique features:
- Transparent for all PROFIBUS DP protocols
- Suitable for PROFIsafe and MPI
- High-integrity telegram checking
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.
