MTL Instruments' 9180 Series redundant Fieldbus power system features N+1 redundancyCONTROL ENGINEERING China版权所有, on-line diagnosticswww.cechina.cn, and modular flexibility. Designed to provide redundant power for eight Foundation fieldbus H1 segments, the fieldbus power system is optimized for use in general purpose and hazardous area high energy trunk architectures which, with the appropriate wiring componentsCONTROL ENGINEERING China版权所有, support fieldbus devices using hazardous area protection techniques. A component of MTL's recently created FieldPlus? brand initiativeCONTROL ENGINEERING China版权所有, the 9180 Series power system is designed to make fieldbus component selection as easy as possible.
Power for the eight Fieldbus segments is provided by two groups of up to three 919x-FP 4-segment power modules operating in N+1 redundant configuration (load sharing). For redundant applications requiring 250 to 500 mA per segment控制工程网版权所有, three 9191-FP power modules are fitted on the carrier for each four-segment group.
For redundant applications initially requiring up to 250 mA per segment控制工程网版权所有, two 9191-FP modules are fitted on the carrier, with the option of adding a third power module to allow for future segment power expansion. Initial capital cost savings of 25% are typical compared to a conventional 1+1 redundant architecture.
