DeltaV™ Distributed CHARMs
We Set the Bar for Electronic Marshalling. Now We're Raising It.
Reduce wiring, lower installation costs, and simplify deployment with DeltaV Distributed CHARMs. Compact enclosures (up to 12 CHARMs) can be installed closer to field devices, while support for M-series controllers makes it easier to add Electronic Marshalling and wireless technologies to existing systems.
More Flexibility. Lower Installation Costs.
Install CHARMs closer to field devices to reduce wiring, lower installation costs, and simplify project execution.
Reduce Total Installation Cost
Reduce project costs by minimizing field wiring, lowering material requirements, and simplifying installation. Locating CHARMs closer to field devices helps decrease labor hours and accelerate project execution.
Improve Flexibility in Combining I/O Types
Easily mix and match I/O types within the same architecture without the constraints of traditional marshalling. Adapt to changing project requirements while maintaining a streamlined system design.
Support for Smart Commissioning
Accelerate startup and commissioning activities with Smart Commissioning capabilities that enable earlier testing, improved quality, and reduced project risk.
Works with Both DeltaV and DeltaV SIS
Leverage a common I/O approach across process control and safety systems. This integrated architecture simplifies engineering, improves consistency, and reduces complexity throughout the project lifecycle.
Reduce the Number of CHARM I/O Cards and Smart Logic Solvers
Optimize system design by supporting more signals with fewer hardware components. Reducing required infrastructure helps lower costs, minimize cabinet space, and simplify maintenance.
Improve Utilization Through Expansions
Expand existing systems without disrupting operations or overhauling infrastructure. Distributed CHARMs make it easy to add capacity where it's needed, helping maximize the value of existing assets and investments.
Frequently Asked Questions
In many cases, DeltaV CHARMs can eliminate marshalling cabinets entirely. Each signal is wired directly to a single-channel module, removing the need for cross-wiring and traditional marshalling panels in industrial automation systems.
DeltaV CHARMs are single-channel and configurable, allowing different signal types, such as analog and digital inputs and outputs, to be mixed within the same enclosure. This provides greater flexibility compared to traditional I/O systems that require separation by signal type.
Yes, DeltaV CHARMs allow I/O changes late in the project lifecycle without requiring rewiring. Because signal types are assigned at the channel level in software, users can modify or add I/O without redesigning cabinets or field wiring.
The primary cost advantage of using DeltaV CHARMs comes from reduced wiring and labor requirements. This includes fewer cables, less need for large cabinets, faster loop checks, and quicker commissioning, which can significantly lower overall installation costs.
Distributed CHARMs help reduce installation costs by decreasing wiring requirements, minimizing engineering effort, reducing the number of required components, and enabling field installation closer to process equipment. Emerson's examples show significant savings in both labor and overall project costs compared to traditional I/O architectures.
DeltaV Distributed CHARMs improve project flexibility by allowing I/O to be installed closer to field devices while supporting mixed I/O types and simplified expansion. This Electronic Marshalling approach helps reduce engineering effort, accommodates project changes more easily, and enables teams to adapt system designs as requirements evolve throughout the project lifecycle.
