-40° to 70°C
The Emerson DeltaV KJ2003X1-BB1 Controller MD Plus Module is a core processing component within the DeltaV distributed control system (DCS) platform, originally developed under the Fisher-Rosemount Systems lineage. Designed for demanding automation environments, this controller module manages process logic execution, I/O communication, and real-time control tasks across the DeltaV architecture. In marine and offshore applications, DeltaV-based PLC & HMI systems are employed in cargo management, power management, ballast control, and machinery automation — making the integrity of each controller module critical to safe and efficient vessel operations.
Key Features
✓ Functions as the primary processing unit within a DeltaV DCS node, executing control strategies and coordinating communication between I/O subsystems and the operator interface.
✓ Rated at 5VDC with a maximum draw of 1.4A, and designed to operate across an extended temperature range of -40°C to +70°C, supporting reliable performance in harsh shipboard environments.
✓ Compatible with the Emerson DeltaV distributed control platform; intended for use within DeltaV controller carrier assemblies — specific chassis and I/O bus compatibility subject to confirmation against system version and configuration.
✓ Suitable for installation in climate-controlled automation panels or control rooms; mounting and enclosure requirements depend on vessel installation standards and system integrator specifications.
✓ Replacement of this module should be carried out by qualified DeltaV-trained personnel; firmware revision (Rev.B) should be verified against the target system version prior to installation to ensure compatibility.
Marine Applications
✓ Cargo and ballast automation systems aboard tankers, bulk carriers, and LNG vessels where DeltaV DCS platforms are used for process control.
✓ Offshore platforms and FPSOs utilising Emerson DeltaV for production process control, safety instrumented functions, and utility system management.
✓ Power management and machinery control systems on large commercial vessels requiring high-reliability PLC & HMI infrastructure.
✓ Drilling vessels and semi-submersibles where DeltaV controllers support wellhead, mud system, or auxiliary equipment automation.
✓ Retrofit and upgrade projects replacing ageing DeltaV controller hardware to maintain system supportability and extend operational lifecycle.
Why Marine Engineers Choose
The Emerson DeltaV MD Plus Controller Module is a trusted component within one of the most widely deployed DCS platforms in marine and offshore environments. Its extended temperature tolerance, established compatibility within the DeltaV ecosystem, and proven field performance make it a practical choice for maintenance, sparing, and system restoration projects.
Ideal For
Tankers, LNG carriers, bulk carriers, offshore production platforms, FPSOs, drillships, semi-submersibles, and any vessel or installation operating an Emerson DeltaV distributed control system requiring controller module spares or replacements.
Technical Support & Compliance
Remote troubleshooting guidance, onboard commissioning support, module testing, and DeltaV system integration assistance are available subject to confirmation of site conditions and system configuration. Repair and retrofit evaluations can be arranged depending on scope. To confirm compatibility and suitability, buyers are encouraged to share nameplate photographs, the full part number and revision, DeltaV system version, controller carrier model, any relevant loop or I/O drawings, and vessel name or IMO number where applicable. All compatibility assessments are subject to confirmation prior to installation.
