DeltaV Electronic Marshalling with CHARMs

Remove the Complexity of Marshalling Field Wires

I/O on Demand Increases Operational Flexibility

Electronic Marshalling offers unmatched flexibility, allowing you to add I/O anywhere in the plant without altering control room cabinets. With its single-channel CHARacterization Modules (CHARMs), it provides I/O type connectivity in a single channel component. CHARMs let you terminate field wiring of any signal type anywhere, eliminating the need for marshalling cabinets, cross-wiring, and excessive wiring. This streamlined approach reduces work, minimizes contact points, and lowers the risk of potential failures.

Eliminate Marshalling

Electronic Marshalling delivers the flexibility to add I/O anywhere in the plant without affecting the control room cabinets. This is possible because Electronic Marshalling provides I/O type connectivity, like AI 4-20mA, AO 4-20mA, AI 0-10V, TC, RTD, DI Dry or Namur, DO High Side, Relays Contact Outputs or Isolated DI and DO for higher currents or higher VAC Voltages, in a single channel component — called a CHARM. CHARMs can be located in hazardous environments like Class1, Division 2 / Zone 2 Group A,B,C,D.

Receive Proactive Alerts

CHARMs connect to the CHARM I/O Card (CIOC), which communicates with multiple controllers. With built-in redundancy for CIOC communication lines and power distribution to the CHARMs, the system proactively alerts you to any field issues. For instance, the CIOC monitors both 24VDC supply inputs and temperature, ensuring reliable operation even when remotely installed in a field enclosure within harsh environments.
