Emerson KL3022X1-BA1 DeltaV AO 4-20mA HART CHARM Module

Product Overview

The Emerson KL3022X1-BA1 functions as a high-density, single-channel Analog Output (AO) Characterization Module (CHARM) within the DeltaV Electronic Marshalling infrastructure. This intelligent interface card converts digital control commands from the DCS core into standard 4-20mA analog current loops to drive final control elements, such as control valve positioners, variable speed drives, and industrial actuators. Simultaneously, the module modulates and demodulates digital HART communication packets over the analog signal line, establishing a bidirectional telemetry link with smart field instruments. We guarantee this HART-enabled analog output module arrives in 100% brand new, original factory-sealed condition.

Engineering Advantages

• Redundant Dual DC/DC Converters Prevent Loop Failure: The module houses a fully integrated dual DC/DC internal power supply matrix. This architecture feeds the loop driving circuitry through independent, parallel power tracks, preventing an isolated component failure within the power stage from dropping loop current or losing control of critical valve positioning.

• Ultra-Slim 1.9 cm Form Factor Maximizes Cabinet Density: The compact 1.9 cm physical profile mounts directly onto the standard CHARM I/O carrier baseplate. This slim footprint strips away bulky, traditional field terminal blocks, allowing systems engineers to condense their marshaling enclosures and install hundreds of channels within shallow, space-constrained junction boxes.

• Severe Shock and Vibration Absorption Protects Internal Silicons: Rugged physical structural reinforcement dampens severe plant environment forces up to 10g shocks and 0.7g continuous vibration. This protection stops trace separation and micro-cracking on delicate internal surface-mount silicons, allowing field installation directly onto offshore production modules and heavy compressor skids.

• Unconditioned Thermal Envelope Lowers Infrastructure Costs: High-grade industrial components guarantee drift-free digital-to-analog tracking across a sweeping -40°C to +70°C temperature span. This wide envelope allows field engineers to deploy the I/O racks in extreme climates without installing expensive, high-maintenance HVAC cooling systems inside the remote instrument enclosures (RIEs).

FAQs

• Does this KL3022X1-BA1 module ship inside original factory packaging?

  Yes. We source and distribute this industrial component exclusively as a 100% brand new, factory-original product. The module remains sealed inside its untouched, original Emerson anti-static protective film within the genuine corporate box, complete with all factory asset labels, quality control tracking barcodes, and original seals.

• Can I replace this individual AO CHARM while the plant loop remains operational?

  Yes. The DeltaV CHARM framework supports full Removal and Insertion Under Power (RIUP). You can snap this module out of its active carrier slot and push this new unit into place without shutting down power to the overall baseplate rail or disrupting communications on adjacent control channels.

• Does this card read digital position feedback from the valve over the HART network?

  Yes. The internal data processor continuously strips the digital HART carrier wave from the analog loop. It streams secondary variables—such as actual valve stem position, target setpoint deviation, and actuator pressure diagnostics—back to your asset management software without introducing lag or skew into the primary 4-20mA control signal.

• What precautions should I observe regarding relative humidity during installation?

  Keep the ambient environment inside the cabinet within the 5% to 95% non-condensing relative humidity specifications. For installations located in humid coastal regions or tropical processing plants, place the carrier assembly inside a sealed, properly rated NEMA 4X or IP66 enclosure to prevent atmospheric condensation from bridging electrical terminal contacts.
