Product Overview
The Emerson VE4060C1 is an 8-wide I/O carrier designed for the DeltaV Electronic Marshalling architecture, serving as the mechanical and electrical backbone for CHARMs (Characterized I/O) modules. Unlike traditional I/O cards that are fixed-function, the CHARMs architecture separates field wiring from signal conditioning—the Emerson VE4060C1 provides the physical mounting, backplane power distribution, and communication pathways that allow individual CHARM modules to be installed and characterized after field wiring is complete . This design significantly reduces engineering lead time and simplifies late-stage modifications to I/O assignments.
The Emerson VE4060C1 supports up to eight CHARM baseplates, with each baseplate accommodating twelve individual CHARM modules, yielding a maximum capacity of 96 independently configurable I/O channels per carrier . The carrier hosts a pair of redundant CHARM I/O Cards (CIOCs) in a primary/standby configuration, ensuring continued operation if one CIOC fails. Communication to the DeltaV controller is handled through redundant Ethernet connections, and power is supplied via dual 24 VDC inputs for fault tolerance .
The Emerson VE4060C1 is distinguished from the similar VE4060C0 by the inclusion of a carrier extension cable, which provides greater flexibility in cabinet layout and allows the carrier to be positioned for easier maintenance access . As a critical infrastructure component in DeltaV systems, the Emerson VE4060C1 enables the scalability and flexibility that define the Electronic Marshalling approach—allowing I/O to be added or reconfigured with minimal disruption to field wiring and cabinet infrastructure .

Main Features and Advantages
Redundant Architecture at Every Level: The Emerson VE4060C1 is engineered with redundancy as a foundational principle. The carrier hosts two CIOCs in a primary/standby configuration, accepts dual 24 VDC power feeds, and provides redundant Ethernet communication paths to the controller . If any single power source, network path, or CIOC fails, the system continues operating without interruption and generates an alarm rather than degrading silently. For critical process applications where an I/O outage could halt production, this layered redundancy is essential.
Electronic Marshalling Efficiency: The Emerson VE4060C1 embodies the core advantage of DeltaV Electronic Marshalling: the decoupling of field wiring from signal type assignment. With traditional I/O, engineers must know the exact signal type (AI, AO, DI, DO, RTD, thermocouple) before ordering cards and wiring terminals. With the Emerson VE4060C1 and CHARMs architecture, field wiring can proceed immediately—the signal type is determined later by simply plugging in the appropriate CHARM module . This reduces project lead time and makes late-stage I/O changes far less disruptive.
Space and Infrastructure Savings: By consolidating up to 96 channels onto a single carrier, the Emerson VE4060C1 dramatically reduces cabinet footprint compared to traditional I/O card racks. A single CIOC on this carrier can replace as many as twelve traditional I/O cards . The integrated backplane eliminates the need for external power and communication cabling between I/O modules, simplifying cabinet wiring and reducing installation labor.
Hot-Swap Maintainability: CHARM modules installed on the Emerson VE4060C1 support hot-swapping, meaning individual I/O channels can be replaced without shutting down the controller or interrupting other channels . Combined with the carrier extension cable that improves physical access, this feature minimizes mean time to repair and supports maintenance during production hours.
