Introduction:
The DeltaV™ CTO CHARM Field Enclosures provide an offthe-shelf solution for faster project execution and reduced installation costs. Field Enclosures are factory tested products and ready for installation in the field. Electronic Marshalling eliminates traditional I/O design tasks and allows field wiring to start long before control strategies are finalized.
The field enclosures are designed for hazardous areas and harsh environments, from extreme temperatures to corrosive gases.
Benefits:
Delivers Electronic Marshalling enabled by CHARMs technology: The CHARM Field Enclosures offer the full benefits of Electronic Marshalling. The individual channels can be defined for any combination of field signal type, as required by the process equipment. This allows for 100 % utilization of channels, regardless of the I/O signal mix. Late changes are easily accommodated with minimal re-engineering and no rewiring.
Reduce system footprint: Equipment room footprint is greatly reduced by replacing traditional marshalling cabinets with field mounted I/O cards.
Eliminate I/O home run cables: Field instrumentation wiring is reduced to the signal pair that connects the field device to the Field Enclosure. Save on home run multi-core cables, cable trays, associated engineering, and documentations.
Significantly reduce cabinet design engineering: The CHARM Field Enclosures are pre-engineered and factory tested. The I/O flexibility allows the same design to serve a wide variety of I/O signals, conditioned individually by the CHARM. Field wiring design is complete at the terminal block.
Fully documented package: Each Field Enclosure is supplied with full documentation and engineering drawings showing internal lay-out, bill of materials, and internal wiring. They are designed to meet local building code and industry best practices in order to deliver proven functionality with minimal costs.
