ProfiHub B4FOR+ – Fiber Optic to Multi Segment Coupler
The B4FOR+ 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 optical data infrastructures offer.
The ProfiHub B4FOR+ 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 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.
