The Emerson DeltaV KJ3222X1-BA1 is a Series 2 Analog Input HART Module designed for use within the DeltaV distributed control system platform developed by Fisher-Rosemount Systems. Supporting the industry-standard 4-20mA signal range with HART communication capability, this module serves as a critical interface between field instrumentation and the DeltaV controller, enabling accurate process variable acquisition. Within the PLC & HMI category, it plays a fundamental role in vessel automation architectures where reliable signal integrity and distributed I/O performance are essential to safe and efficient operations.
Key Features
✓ Analog input module supporting 4-20mA field signals with integrated HART communication protocol for intelligent device interfacing and diagnostics.
✓ Specified operating voltage inputs of 12VDC at 150mA and 24VDC at 300mA / 30mA, with an operating temperature range of -40°C to +70°C, suitable for demanding shipboard environments.
✓ Designed for compatibility with the Emerson DeltaV Series 2 distributed control system, integrating directly with DeltaV controllers, I/O subsystems, and associated marshalling infrastructure.
✓ Suitable for installation within control cabinets and automation enclosures in machinery control rooms, cargo control rooms, or integrated bridge systems, subject to installation configuration.
✓ As a modular I/O component, the KJ3222X1-BA1 can be replaced or retrofitted within existing DeltaV Series 2 architectures, supporting system maintenance and continuity of automation functions onboard.
Marine Applications
✓ Tankers and bulk carriers utilising DeltaV-based integrated automation systems for cargo monitoring, ballast control, and machinery process management.
✓ Offshore platforms and FPSOs where Fisher-Rosemount DeltaV systems manage complex process control loops requiring reliable analog signal acquisition.
✓ LNG and LPG carriers employing HART-enabled instrumentation for cargo temperature, pressure, and flow monitoring within automated control architectures.
✓ Drillships and semi-submersibles where DeltaV distributed control systems oversee critical process variables across drilling and utility systems.
✓ Naval auxiliaries and large commercial vessels integrating DeltaV PLC & HMI platforms for engine room automation and process control redundancy.
Why Marine Engineers Choose
The Emerson DeltaV Series 2 HART Analog Input Module is valued for its robust signal handling, HART diagnostics capability, and direct compatibility with established DeltaV control architectures — making it a dependable choice for maintaining system continuity and minimising downtime during scheduled maintenance or unplanned replacements at sea.
Ideal For
Tankers, bulk carriers, LNG/LPG vessels, FPSOs, offshore drilling units, and large commercial or naval auxiliary vessels operating Emerson DeltaV distributed control and automation systems.
Technical Support & Compliance
Remote troubleshooting guidance, onboard technical support, and commissioning assistance are available to help integrate or replace this module within existing DeltaV systems, subject to confirmation of site configuration. Repair evaluation, retrofit assessment, and system integration support can be arranged depending on scope and vessel schedule. To confirm compatibility and suitability, buyers are advised to share nameplate photographs, full part numbers, DeltaV system version and controller model, engineering drawings or I/O lists where available, and vessel name or IMO number. All compatibility and compliance representations are subject to confirmation based on the specific installation and system configuration.
