Product Overview
The Emerson VE4060C1 is an 8-wide CHARM I/O Carrier serving as the central mechanical and electrical backbone of the DeltaV Electronic Marshalling architecture, developed by Emerson Process Management for distributed control systems that demand channel-level flexibility and fault tolerance. Rather than containing signal-termination points itself, the VE4060C1 hosts a redundant pair of CHARM I/O Cards (CIOC) and interconnects them with up to eight CHARM Baseplates mounted below on the same vertical DIN rail, each of which carries twelve individually characterized CHARM modules — giving the carrier a theoretical maximum of 96 independently configurable field-signal channels per node.
Through its integrated backplane, the Emerson VE4060C1 distributes redundant 24 V DC field power, 6.3 V DC CHARM power, and the redundant RS-485 communication bus that links every baseplate to the CIOC pair, while the redundant Ethernet I/O modules (IOPs) on the carrier connect the node to as many as four DeltaV controllers — SX, SD Plus, MD Plus, MQ, MX, or PK — over 10/100BASE-TX copper or 100BASE-FX fiber media. The “C1” suffix distinguishes this carrier from the VE4060C0 variant by the inclusion of a carrier extension cable, providing layout flexibility in cabinets where DIN-rail real estate or maintenance access is constrained.
As part of the wider CHARMs ecosystem, the Emerson VE4060C1 enables the core Electronic Marshalling value proposition: field wiring can be landed in any order on the baseplates without regard to signal type, because the signal characterization is defined later by simply inserting the appropriate CHARM — analog input, analog output, discrete input, discrete output, RTD, thermocouple, or power — which the DeltaV configuration database auto-senses and assigns to any of the four supported controllers with a single drag-and-drop action. Rated for Class I Division 2 / Zone 2 hazardous locations, conformal coated to ISA-S71.04 G3 harsh-environment standards, and operating across a −40 °C to +70 °C envelope, the VE4060C1 is equally at home in central marshalling cabinets and field-mounted junction boxes across refining, petrochemical, power generation, LNG, mining, and offshore production facilities worldwide.
