The Emerson Fisher-Rosemount KJ4002X1-BA1 is an 8-Wide Vertical Carrier Left-Hand (LH) Controller, supplied complete with a DeltaV Top Extender Cable. Forming a core structural and power-distribution component within the Emerson DeltaV distributed control system (DCS), this carrier provides both local bus circuit power (12.6VDC, 15A) and field circuit power (250V, 6.5A) to seated I/O modules. It is widely deployed across marine and offshore automation installations where reliable, rack-based process control is essential to safe vessel operation.
Key Features
✓ Delivers dual power rails — 12.6VDC at 15A for local bus circuits and 250V at 6.5A for field circuits — supporting multiple I/O modules seated within the carrier.
✓ 8-wide vertical carrier format accommodates a full complement of DeltaV I/O modules in a compact vertical orientation, optimising panel space in confined marine control room environments.
✓ Supplied with the DeltaV Top Extender Cable (KH4002X1-8E1, PN 12P4048X012, DWG Rev C), enabling system expansion or interconnection with adjacent carrier assemblies subject to system configuration.
✓ Designed for integration within Emerson DeltaV DCS architectures; compatibility with specific DeltaV system versions, controllers, and I/O card types should be confirmed against the installed system configuration.
✓ Direct replacement or retrofit applications should reference the revision level (Rev G) and nameplate data to confirm interchangeability within the target installation — subject to confirmation.
Marine Applications
✓ Process automation and control on oil tankers, LNG carriers, and chemical tankers where DeltaV DCS platforms manage cargo handling, ballast, and machinery systems.
✓ Offshore platforms and FPSOs utilising Emerson DeltaV for integrated process control, shutdown logic, and field instrumentation management.
✓ Engine control room automation aboard large merchant vessels, supporting monitoring and control of auxiliary machinery and power management systems.
✓ Drillships and semi-submersibles where DeltaV-based control cabinets govern drilling process variables and safety-critical I/O.
✓ Newbuild and retrofit automation projects requiring standardised DeltaV carrier hardware to expand or replace existing I/O infrastructure in ship control stations.
Why Marine Engineers Choose
Marine engineers and automation teams rely on Emerson Fisher-Rosemount DeltaV carrier hardware for its proven reliability in demanding shipboard environments, straightforward module integration, and the availability of genuine replacement parts that maintain system integrity without requiring full cabinet redesign.
Ideal For
Oil & gas tankers, LNG and chemical carriers, FPSOs, offshore drilling units, platform supply vessels, and any commercial vessel operating an Emerson DeltaV distributed control system requiring carrier-level I/O infrastructure support.
Technical Support & Compliance
Remote troubleshooting, onboard commissioning guidance, system integration support, and compatibility assessment are available to assist with installation or replacement of this carrier unit. To confirm suitability for your application — subject to confirmation — buyers are encouraged to share nameplate photographs, the full part number and revision, DeltaV system version and controller model, existing cabinet drawings or layout diagrams, and vessel name, IMO number, and scope of work. This ensures the correct hardware configuration is identified prior to installation.
