F2D0-FB-EX4.CGS Pepperl+Fuchs-FieldBus Field Barrier

he High-Power Trunk concept enables maximum cable distance and device count per segment while at the same time offering intrinsically safe instrument connections according to FISCO or Entity.

It decisively reduces effort for validation of intrinsic safety. The FieldConnex FieldBarrier was the first fieldbus coupler with galvanic isolation between the intrinsically safe outputs and the trunk. The main line or home-run cable (trunk) provides ample power to the segment. Each output of the FieldBarrier limits the energy (intrinsically safe) and is designed to power one field instrument. The instrument can be installed in Zone 0/Div. 1. The FieldBarrier itself is typically installed in Zone 1/Div. 2.

This combination of ignition protection methods enables maximum design freedom for the fieldbus infrastructure: long cable runs and high device counts are possible at the same time. This comes with maximum safety, as hot work is permitted at the device level.
