FOUNDATION Fieldbus Design Considerations …

1 Reference ManualPlantPAx Process Automation System: FOUNDATION Fieldbus Design ConsiderationsCatalog Numbers 1757-FFLDx, 1757-FFLDCxImportant User InformationSolid-state equipment has operational characteristics differing from those of electromechanical equipment. Safety Guidelines for the Application, Installation and Maintenance of Solid State Controls (publication available from your local Rockwell Automation sales office or online at ) describes some important differences between solid-state equipment and hard-wired electromechanical devices. Because of this difference, and also because of the wide variety of uses for solid-state equipment, all persons responsible for applying this equipment must satisfy themselves that each intended application of this equipment is no event will Rockwell Automation, Inc.
