Engineers have long struggled with how to use Fieldbus in hazardous areas. The installation of Intrinsically-Safe (I.S.) fieldbus has typically required the use of installation schemes mixing wiring methods such as Division 1 and Division 2 (Zones 0, 1, 2). However, new concepts such as the High-Power Intrinsically-Safe Trunk allow for the use of fieldbus in hazardous areas without complex installation. This white paper reviews the different methods of fieldbus installation in hazardous areas and breaks down the advantages and drawbacks of each.
