Main Features and Advantages
Cable-inclusive ordering discipline: The defining differentiator of the Emerson VE4060C1 CHARMs2 is that the carrier extension cable is embedded in the manufacturer part number itself. On multi-cabinet and multi-row installations this matters operationally — receiving teams can verify at goods-inward that the cable scope matches the planned carrier route before the hardware is released to construction, eliminating the all-too-common scenario where an I.S. carrier arrives on site while its extender cable sits weeks behind on a separate delivery. Procurement planning, spares provisioning, and commissioning schedules all inherit that predictability.
Eight-slot modularity for staged projects: The Emerson VE4060C1 CHARMs2 supports a phased field-wiring workflow: the carrier and terminal-block positions can be installed and landed early, while the actual M-series I.S. I/O cards are added later as the commissioning schedule dictates. This separation between infrastructure installation and functional I/O population decouples the I&E cable-pull schedule from the control-strategy development schedule, a core value proposition of DeltaV modular I/O architecture.
Integrated power distribution and noise management: Rather than requiring external power cabling to feed each slot, the Emerson VE4060C1 CHARMs2 distributes backplane power and bussed 24 V DC field power through the carrier body, with an internal shield ground bar to isolate and drain field noise away from system power. The result is a cleaner signal path for low-level analog signals, fewer field terminations, and a lower installed cost per I/O point.
Engineered for harsh and hazardous environments: With conformal coating, a Class G3 corrosion rating, a –40 °C to +70 °C operating window, and FM, CSA, ATEX, and marine (IACS E10, ABS, DNV) certifications, the Emerson VE4060C1 CHARMs2 is qualified for installation in Zone 2 and Class I Division 2 hazardous locations as well as protected field junction boxes. This makes it legitimate to locate the carrier closer to the field devices — reducing multi-core home-run cable runs and cabinet footprint in the central equipment room.
Plug-and-play M-series integration: Once seated on the T-type DIN rail and connected through the LocalBus Isolator boundary, the Emerson VE4060C1 CHARMs2 is automatically recognized by the DeltaV controller; additional carriers can be added online without system shutdown. M-series I/O cards snap into the carrier with keyed connectors that prevent wrong-card insertion, and the supporting modular design scales from a single carrier up to eight 8-wide carriers — up to 64 I/O interfaces — under one M-series controller.
Application Field
The carrier is deployed wherever DeltaV M-series intrinsically safe I/O is used to bring field signals into a DCS from a hazardous-area process environment. In upstream oil and gas, the carrier supports wellhead control panels, separator trains, gas dehydration skids, and produced-water packages where proximity probes, transmitters, and solenoid valves sit in Zone 1 or Zone 2 areas and must be interfaced through intrinsically safe barriers. In refining and petrochemical operations, the is a standard element of DCS I/O cabinets serving distillation, hydrotreating, reformer, and flare systems, where the I.S. segment handles signals that terminate at field devices located inside the battery limit.
Power generation plants — combined-cycle gas turbines, coal-fired boilers, balance-of-plant instrumentation — use the carrier to extend M-series I/O into burner management, fuel skid, and cooling-tower applications where hazardous-area classification applies to portions of the measurement loop. In pharmaceutical and fine chemical production, the supports batch reactor and solvent-handling areas where ATEX zoning is enforced, while the carrier’s clean indoor cabinet mounting fits the hygienic and audit-driven constraints of those facilities. Water treatment, LNG, terminals, and marine/offshore topsides round out the deployment profile, with the marine certifications extending its applicability to vessel-based and FPSO installations.
Beyond original project builds, the plays a major role in brownfield modernization and spares management: as legacy DCS assets migrate to DeltaV M-series or as operators consolidate multiple vendor I/O into a single DeltaV architecture, the carrier-inclusive-with-cable ordering format reduces the number of procurement line items, simplifies FAT planning, and ensures that IS segment sequencing rules are honored from the first receipt on site.
