Emerson‘s DeltaV™ Electronic Marshalling – Flexible and Cost-Effective Control System I/O

DeltaV™ Electronic Marshalling is an advanced solution designed to improve control system I/O performance. It offers unmatched flexibility and ease of use. This system simplifies wiring, reduces installation costs, and enhances operational efficiency. As a result, it is an excellent choice for industrial automation.

At its core, DeltaV™ Electronic Marshalling uses the CHARM I/O Card (CIOC), which supports up to 96 configurable channels. This architecture is ideal for multi-core home run cables within centralized marshalling cabinets. Additionally, it can be installed in field junction boxes, lowering system design and installation costs. The entire system includes fully redundant communications, ensuring continuous and reliable operation.

Key Features of DeltaV™ Electronic Marshalling

• Flexible I/O placement – Add I/O anywhere using a standard Ethernet infrastructure.
• Customizable CHARM I/O architecture – Configure each channel based on specific field device needs.
• Cost-effective system design – Eliminate internal cabinet cross-wiring and reduce space requirements.
• Fully redundant communication – Ensure system stability with backup components.
• Hazardous location compliance – All parts meet Class 1/Div 2 or Zone 2 safety standards.
• Easy installation and configuration – Set up the system quickly using intuitive software tools.

How DeltaV™ Electronic Marshalling Benefits You

1. Place I/O Anywhere You Need It

DeltaV CIOC offers exceptional flexibility for control system I/O. You can add I/O anywhere using standard Ethernet infrastructure. Whether in a local cabinet or a remote enclosure miles away, installation is quick and simple. Each I/O card updates signals to up to four controllers every 50 milliseconds, ensuring fast and accurate control.

2. Customize Each Channel

The CHARM I/O architecture allows full customization of each channel. Every instrument signal connects to any terminal block, eliminating concerns about signal types. Once connected, the channel is assigned electronically to one of four controllers. This setup simplifies wiring and improves efficiency.

3. Reduce System Costs

By using DeltaV™ Electronic Marshalling, you can significantly cut costs:

• No need for cross-wiring inside cabinets.
• Smaller system footprint, saving valuable space.
• Simplified I/O assignments, reducing complexity.
• Faster testing processes, minimizing Factory Authorized Testing (FAT) costs.
• Late-stage modifications without requiring rewiring.

With this system, installation and control strategies remain separate, ensuring a smooth workflow. Teams can begin wiring early, knowing that adjustments can be made later. This flexibility improves project timelines and reduces unexpected costs.

4. Ensure Reliable Performance with Full Redundancy

The CIOC’s fully redundant design enhances system stability:

• Each carrier holds two I/O cards.
• Redundant primary and secondary network communication modules.
• Dual 24V DC power inputs prevent downtime.
• Redundant CHARMs baseplate connections ensure channel stability.

With these safeguards in place, the system remains operational even if one component fails.

5. Use in Harsh Environments

DeltaV CIOC components meet Class 1/Div 2 or Zone 2 safety standards, making them ideal for hazardous locations. They also feature extended temperature tolerance and a G3-rated protective coating. These factors allow installation inside field-mounted junction boxes, reducing equipment room requirements and minimizing wiring infrastructure.

6. Quick and Easy Setup

DeltaV™ Electronic Marshalling simplifies both physical installation and software setup. Key advantages include:

• Snap-together components that secure with DIN-rail latches.
• Interlocking carrier connectors for faster installation.
• Automatic CHARMs detection, preventing incorrect configurations.
• Drag-and-drop channel assignments for quick setup.

With this system, configuring 96 I/O channels takes only minutes.
