One fiber-optic channel, split into 2 ports

The ProfiHub B2FOR+ is a cost-effective solution to link PROFIBUS fiber optic to multiple RS 485 segments and vice versa. Additional to the other fiber optic repeaters, this module enables the installation of a ring topology, of which the status can be remotely monitored via the ComBricks web browser.

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

ProfiHub B2FOR+ – Fiber Optic to Multi-Segment Coupler

The B2FOR+ supports multiple fiber optic topologies; ring-, point-to-point, bus, and star. The protocol transparency without configuration, allows direct integration in existing PROFIBUS networks to benefit from the advantages of optical data infrastructures offer.

The ProfiHub B2FOR+ is equipped with 2 galvanic isolated RS 485 channels utilising a maximum of 31 devices per channel.
