DeltaV™ Controllers & I/O

Designed for flexibility, DeltaV provides multiple controller and I/O platform choices to suit your requirements

Tailor Your System with Versatile Controllers & I/O Hardware

DeltaV Controllers & I/O enable scalability and flexibility to meet your specific requirements and ensure you’re getting the best value out of your automation. Our unique flexible field architecture delivers I/O on demand—providing you the I/O you want, when you want it, and where you want it. Now you can decouple the process design from the I/O infrastructure design to easily incorporate late process changes into the automation system.

DeltaV IQ Controller Overview

Featured Technologies

Introducing the DeltaV IQ Controller – the next evolution in process control technology. Designed to augment highly engineered, built-for-purpose industrial controllers, the IQ Controller brings greater flexibility, scalability, and efficiency to modern control systems.

Electronic Marshalling delivers the flexibility to add I/O anywhere in the plant without affecting control room cabinets.

CHARMs allows field wiring of any signal type to be terminated anywhere. This means no marshalling cabinet or cross-wiring, fewer wires, much less work, and fewer contact points for potential failures.

Leveraging the powerful functionality of the PK Controller with the added advantage of flexibility capacity.

Reduce upfront investment and complexity with subscription-based DeltaV system.

Frequently Asked Questions

CHARMs allow each channel to be configured independently, so engineering teams can accommodate signal type changes without rewiring or redesigning controllers and I/O cards. This flexibility helps reduce project delays caused by late design modifications.

DeltaV Electronic Marshalling removes many of the cross-wiring and terminal block requirements associated with traditional marshalling cabinets. By assigning signals in software rather than hardwiring them to specific card locations, plants can significantly simplify cabinet design and field wiring.

Traditional I/O cards require specific signal types to be assigned to dedicated card locations. CHARMs allow each channel to be individually configured, making it easier to manage mixed signal types, accommodate project changes, and reduce unused I/O capacity.

Because signal assignments are handled through software rather than physical wiring changes, commissioning and installation activities can often be completed faster. This allows project teams to manage design revisions with less impact on construction and startup schedules.

Yes. By reducing the need for traditional marshalling infrastructure, DeltaV Electronic Marshalling can simplify cabinet layouts and decrease overall panel space requirements, especially in large I/O installations.

CHARM-based I/O can be installed closer to process equipment, packaged units, and remote assets. This reduces homerun wiring requirements while maintaining integration with the DeltaV distributed control system (DCS).

DeltaV's flexible I/O architecture allows additional channels to be added and configured with less disruption than traditional fixed-I/O designs. This helps facilities expand or modify systems as operational requirements change.
