The Fisher Rosemount KJ2102X1-CA1 is an RS3 Migration Carrier designed to support the controlled transition from legacy RS3 Distributed Control System (DCS) architectures to modern control platforms. As a key component within the Marine Control System category, this carrier provides the physical and electrical interface necessary to retain existing field wiring and I/O infrastructure during system migration, reducing downtime and installation cost. Onboard vessels, reliable control system continuity is operationally critical, and migration carriers such as this play a central role in ensuring that automation upgrades do not compromise ongoing plant or machinery control.
Key Features
✓ Functions as a migration carrier within the Fisher Rosemount RS3 DCS ecosystem, enabling retrofit and system upgrade while preserving existing field wiring and I/O configurations.
✓ Rated at 12.6 VDC input at 12.8 A and 12.6 VDC output at 8 A, as indicated on the nameplate — all other electrical or environmental specifications are subject to confirmation against applicable documentation.
✓ Compatible with the Fisher Rosemount RS3 control system platform; compatibility with specific controllers, I/O modules, or expansion hardware beyond the RS3 architecture should be confirmed against system configuration and revision details.
✓ Suited for installation within protected control equipment enclosures or machinery control rooms; mounting arrangement, environmental ratings, and enclosure requirements depend on the vessel’s system layout and should be verified prior to installation.
✓ Intended as a service and upgrade component for vessels undergoing DCS migration; sourcing a direct replacement carrier maintains system integrity and avoids the need for full I/O rewiring during modernisation projects.
Marine Applications
✓ Offshore supply vessels and platform support vessels operating legacy Fisher Rosemount RS3 DCS installations requiring controlled system migration.
✓ Tankers and bulk carriers where existing automation infrastructure is being upgraded without disruption to cargo handling or machinery control systems.
✓ Drill ships and semi-submersibles with complex, integrated control systems transitioning from RS3 to current-generation DCS or hybrid platforms.
✓ Naval auxiliaries and government vessels maintaining long-lifecycle control systems where migration carriers enable phased modernisation strategies.
✓ LNG and LPG carriers where machinery automation reliability is paramount and system upgrade components must interface precisely with existing field instrumentation.
Why Marine Engineers Choose
Marine engineers working with Fisher Rosemount RS3 systems select this migration carrier because it provides a proven, manufacturer-defined pathway for system upgrades — preserving existing field connections and reducing the scope and risk of control system modernisation projects aboard vessels with complex automation requirements.
Ideal For
Offshore vessels, tankers, bulk carriers, drill ships, LNG & LPG carriers, naval auxiliaries, and any vessel class operating a Fisher Rosemount RS3 DCS installation undergoing planned migration or upgrade to a current-generation control platform.
Technical Support & Compliance
Remote and onboard technical support is available to assist with installation, testing, commissioning, and system integration of this migration carrier within existing RS3 or successor control architectures. Retrofit and upgrade guidance can be provided subject to confirmation of the vessel’s current system configuration. To confirm compatibility and suitability, buyers are encouraged to share nameplate photographs, the full part number and revision details, system drawings or I/O lists, the control system model and software version, and vessel name or IMO number where applicable. All compatibility and configuration statements are subject to confirmation against actual system documentation and site conditions.
