The Emerson Fisher DeltaV Serial Interface Module (KJ3241X1-BA1, Rev D) is a Series 2 serial interface card designed for use within the DeltaV distributed control system platform by Emerson Process Management. As a PLC & HMI category component, it provides serial communication capability between the DeltaV controller infrastructure and connected field devices or subsystems. This module plays a critical role in maintaining reliable data exchange across process automation networks, making it essential for the integrity of control and monitoring operations onboard vessels and in industrial marine environments where DeltaV systems are deployed.
Key Features
✓ Serial interface functionality within the DeltaV Series 2 architecture, enabling communication between controllers and serial-protocol field devices or subsystems.
✓ Localbus power rating of 12VDC at 300mA and an operating ambient temperature range of -40 to 70°C, as stated on the nameplate — making it suitable for demanding environmental conditions typical of marine and offshore installations.
✓ Compatible with Emerson Fisher Rosemount DeltaV distributed control systems; intended for installation within DeltaV controller enclosures or marshalling cabinets — subject to confirmation of specific system version and configuration.
✓ Designed for installation in protected control room or equipment room environments; mounting and enclosure requirements follow standard DeltaV hardware guidelines — consult system documentation to confirm fit and compatibility.
✓ Replacement of this module should be carried out by qualified automation technicians familiar with DeltaV hardware; firmware revision and system configuration compatibility should be verified prior to installation.
Marine Applications
✓ Integrated automation systems (IAS) and distributed control platforms aboard LNG carriers, tankers, and offshore production vessels where DeltaV is the primary control architecture.
✓ Serial device integration for connecting legacy instrumentation, third-party subsystems, or serial-protocol transmitters to the DeltaV control network in marine and offshore environments.
✓ Process control applications on FPSOs, drilling rigs, and offshore platforms requiring robust serial communication modules within harsh ambient temperature conditions.
✓ Cargo management, machinery monitoring, and auxiliary system control onboard vessels where Emerson DeltaV systems provide the backbone automation infrastructure.
✓ Retrofit and upgrade projects involving DeltaV system expansions or serial interface capability additions on vessels with existing Emerson process automation installations.
Why Marine Engineers Choose
The Emerson Fisher DeltaV Serial Interface Module is a purpose-built component within a well-established distributed control platform, offering engineers a reliable path to maintaining serial communication integrity across complex onboard automation networks. Its wide temperature tolerance and defined electrical ratings make it a dependable choice for marine and offshore operational demands.
Ideal For
LNG carriers, crude oil tankers, FPSOs, offshore drilling rigs, semi-submersibles, production platforms, and any commercial or industrial vessel operating Emerson DeltaV distributed control systems requiring serial interface expansion or module replacement.
Technical Support & Compliance
Remote troubleshooting guidance, onboard commissioning support, integration assistance, and retrofit consultation are available for this module and the wider DeltaV platform — subject to confirmation of system configuration and vessel requirements. Testing and functional verification prior to installation is strongly recommended. To confirm compatibility and suitability, buyers are encouraged to share nameplate photographs, the full part number and revision, DeltaV system version and controller type, existing hardware drawings or loop diagrams, and where applicable, vessel name, IMO number, and project scope. All compatibility assessments are subject to confirmation based on the information provided.
