More Fieldbus Power for Hazardous Location Applications

摘要

Wondering if you can connect all your devices to a fieldbus and keep them running? The High Power Trunk concept might be your answer. Process industry engineers who use fieldbus in their hazardous location applications (Class I, Division 1 and Class I, Division 2) are looking for additional power that will let them connect more instruments to their fieldbus segments. Three emerging methods promise to help meet this need: FISCO (Fieldbus Intrinsically Safe COncept), FNICO (Fieldbus NonIncendive COncept) and the High Power Trunk concept.
