9189 fieldbus power supply
The 9189 fieldbus power system is designed to provide redundant power for eight, or four, Foundation™ fieldbus H1 segments for use with all fieldbus systems. It is optimised 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 supply has been designed to optimise cabinet layouts, maximising the number of fieldbus segments powered per cabinet while providing space for installing and maintaining cable connections and minimising the operating temperature.
