Product Overview
The Emerson VE4060C1 is an 8-wide CHARM I/O Carrier within the DeltaV Electronic Marshalling architecture, serving as the backbone that hosts the CHARM I/O Cards and aggregates redundant power and communication to the CHARMs installed throughout a DeltaV distributed control system. The VE4060C1 is not an I/O module itself and does not contain signal-termination points; rather, it is the carrier assembly onto which a redundant pair of CHARM I/O Cards (CIOC) is mounted, and through which those cards connect to up to eight CHARM Baseplates. In this role, the Emerson VE4060C1 is the central node that turns individually characterized field-signal channels into an organized, fault-tolerant I/O network.
Each CHARM Baseplate connected to the carrier supports 12 CHARMs and their removable terminal blocks, giving the VE4060C1 a theoretical maximum of 96 independent, individually configurable field channels across its eight baseplate ports. Power is supplied through redundant 24 V DC inputs, and communication is carried over redundant Ethernet I/O networks — primary and secondary — so that a single power-supply or network failure does not interrupt the I/O. The carrier’s communication modules, CIOC cards, and connected CHARMs are all designed to operate as a fully redundant chain down to the individual channel level.
The defining difference between the Emerson VE4060C1 and the closely related VE4060C0 is the inclusion of a carrier extension cable. This cable provides flexibility in carrier mounting location, allowing the carrier to be positioned away from the baseplate row — useful in cabinets where DIN-rail space is constrained or where maintenance access needs to be improved. The carrier, its CIOC cards, baseplates, and CHARMs all connect with secure DIN-rail latches and self-keying interlocks, supporting tool-free installation and channel auto-sensing directly into the DeltaV configuration database.

Main Features and Advantages
The Emerson VE4060C1 provides the physical and electrical backbone for DeltaV Electronic Marshalling, a design that removes the need for traditional marshalling cabinets and the cross-wiring they contain. By carrying redundant 24 V DC power and redundant Ethernet communication to every connected CHARM, the carrier ensures that I/O remains available even when a power supply or network segment fails. This full-channel redundancy is a key reason Electronic Marshalling delivers higher plant availability than conventional fixed-type I/O cards.
A major practical advantage of the is the flexibility provided by its carrier extension cable. In dense or awkwardly laid-out control cabinets, the cable allows the carrier to be mounted in a more accessible or better-ventilated location rather than being forced onto the same DIN rail as the baseplate row. This reduces installation effort, improves cable management, and makes routine maintenance less disruptive.
The Emerson VE4060C1 supports up to 96 individually configurable channels across eight baseplates. Each CHARMs channel is independently characterized, galvanically isolated, and fault-isolated, so a short circuit or overvoltage on one field instrument is contained to that single channel without affecting its neighbors. Mechanical self-keying prevents a CHARM from being inserted into the wrong terminal block, eliminating a common source of wiring and replacement errors.
Commissioning is simplified by the DeltaV architecture: CHARMs are auto-sensed when inserted, and the I/O definition is created automatically in the DeltaV configuration database. This allows field wiring to be completed independently of control logic, supports late design changes without rewiring, and enables any channel to be electronically assigned to any controller in the system. The therefore reduces both engineering time and startup risk on DeltaV migration and expansion projects.
