Eaton offers three flexible solutions for redundant fieldbus power supplies:

The MTL 9180 range of redundant fieldbus power supplies should be selected for all new applications. Its unique N+1 redundancy approach provides flexibility to the system designer by meeting the initial project demands with 2 power supply modules/segment, while allowing a third power supply to be added later to meet expansion requirements. This typically delivers 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/segment.  

9180 range redundant fieldbus power supplies offer the following benefits:

• Eight segment power supplies with flexible N+1 redundancy
• Fully isolated
• Hot swappable power modules
• Low power dissipation
• Choice of rising cage clamp screw or spring clamp terminals
• Screen passthrough or ground option without accessories
• On-line diagnostics option
• Pluggable trunk surge protection option
• Support for Ex ic spurs when used with F300 range of Megablocks and F30 Ex ic adaptor

The MTL F800 range is an eight-segment, high density fieldbus power supply. The module carriers provide wire terminations for eight fieldbus segments as well as mounting two F801 or F802 power supply modules. The F801 power supply modules provide 8 outputs of 21.5V, 350mA. The F802 power supply modules provides 8 outputs of 28V, 500mA for applications with fieldbus trunk lengths greater than 600m or heavily loaded fieldbus barrier applications. Both options ensure that one Fieldbus terminator is included for each segment. The F800 carriers themselves are completely free of electronic components to maximize their MTBF and system availability.

F800 range redundant fieldbus power supplies provide:

• Eight segment power supplies with 1+1 redundancy
• Low power dissipation
• Choice of rising cage clamp screw or spring clamp terminals
• On-line diagnostics option
• Horizontal and vertical DIN-rail mounting

Finally, our legacy MTL FPS range power conditioners provide redundant fieldbus power for a single fieldbus segment and are available with or without a built-in terminator.

• High power output
• Two levels of power redundancy
• Component failure alarm
• Integrated fieldbus terminator
• Simplified power wiring
