The MTL 9180 Series redundant Fieldbus power supplies are designed to provide redundant power for up to eight FOUNDATION fieldbus H1 segments and are suitable for use with all fieldbus systems. They are optimized for use in general purpose and hazardous area High Energy Trunk architectures which, with the appropriate FieldPlus wiring components, supports fieldbus devices using all hazardous area protection techniques. The power supplies are designed to optimize cabinet layouts, achieving the maximum number of fieldbus segments powered per cabinet while providing space for installing and maintaining cable connections and reducing the operating temperature. The F809F-Plus physical layer Fieldbus Diagnostics Module may be installed on any 9180 carrier to automatically collect and distribute additional diagnostic information for each of the eight fieldbus segments.
The 9180 series should be selected for all new applications. Its unique N+1 redundancy approach provides flexibility to the system designer meeting the initial demands of the project with two power supply modules per segment, while having the ability to add a third power supply later to meet expansion requirements. The advantage to the operator is typically a 25% savings in initial capital cost compared to a conventional, 1+1 redundant architecture. High system availability is achieved with the use of passive components for power conditioning, galvanic isolation and power regulation delivering redundant fieldbus power at up to 28V, 500mA per segment. The product range also includes power supply modules that can be used to provide power for segments with Ex ic spurs, to be used in conjunction with the MTL F300 range of Megablock device couplers and the F30 Ex ic adaptor.
