The Emerson Fisher-Rosemount DeltaV MD Plus Controller Module (KJ2003X1-BB1) is a programmable logic controller component forming part of the DeltaV distributed control system architecture. Designed for advanced process automation, this module provides primary control functionality within the DeltaV platform, managing I/O communications, process logic execution, and localbus power distribution. It is widely deployed across marine and industrial installations where reliable, scalable process control is critical — including vessel automation, machinery management, and cargo handling control systems. As a PLC & HMI category component, it plays a central role in maintaining continuous, deterministic control over automated processes onboard.
Key Features
✓ Functions as the primary process controller within the DeltaV distributed control system, executing control logic and managing connected I/O subsystems.
✓ Localbus power rating of 5VDC at 1.4A maximum, with an operating ambient temperature range of -40°C to 70°C and Temperature Rating T4, as specified on the nameplate.
✓ Compatible with the Emerson DeltaV control system platform; intended for integration within DeltaV controller backplanes and associated I/O infrastructure — system version compatibility subject to confirmation.
✓ Suitable for installation in protected enclosures within control rooms, automation panels, or dedicated PLC cabinets onboard vessels; mounting configuration and environmental protection class subject to installation-specific requirements.
✓ As a controller module, replacement or upgrade planning should account for firmware revision, system configuration backup, and re-commissioning requirements within the DeltaV environment.
Marine Applications
✓ Vessel automation and integrated bridge systems requiring distributed process control across multiple I/O nodes.
✓ Cargo and ballast management systems on tankers, bulk carriers, and offshore support vessels where precise process logic is essential.
✓ Engine room automation and machinery monitoring systems on merchant vessels, requiring reliable PLC-based control infrastructure.
✓ Offshore platforms and FPSOs utilising DeltaV-based process control for production, utility, and safety system management.
✓ Retrofit and upgrade projects on vessels transitioning legacy control systems to the Emerson DeltaV distributed control architecture.
Why Marine Engineers Choose
The Emerson DeltaV MD Plus Controller Module is a well-established platform in marine and offshore process automation, valued for its robust operating temperature range, compatibility within the broader DeltaV ecosystem, and the reliability expected of Emerson Fisher-Rosemount control hardware in demanding operational environments.
Ideal For
Tankers, bulk carriers, offshore support vessels, FPSOs, drillships, platform supply vessels, and any vessel or installation operating an Emerson DeltaV distributed control system requiring controller module replacement or inventory support.
Technical Support & Compliance
Remote troubleshooting guidance, onboard commissioning support, system integration assistance, and retrofit consultancy are available subject to confirmation of the specific DeltaV system version and configuration. Testing, repair assessment, and compatibility verification can be arranged depending on scope. To confirm suitability for your installation, buyers are encouraged to share nameplate photographs, the full part number and revision, DeltaV system version and controller backplane model, any relevant engineering drawings or I/O lists, and vessel name or IMO number where applicable. All compatibility and interoperability claims are subject to confirmation based on the information provided.
