        Overview Manuals Version Fit Loop Recovery Migration Scope Applications

        Features:

        • Generation-controlled spare: Keeps an earlier DeltaV output position tied to the hardware family recorded for the running project.
        • Retained field destination: A verified terminal relationship lets the replacement card return to the established loop assignment.
        • HART-capable legacy path: Compatible final-element information remains available without adding a separate communication cable.
        KJ3221X1-BA2 occupies the removable-electronics position in an earlier DeltaV M-series analog-output assembly.

        The existing terminal block preserves the field conductors while the card converts the controller value and communicates with the system.

        Selection begins with the running DeltaV release, installed terminal code and channel record because those items establish whether the outage is a card repair or a platform change.

        Apter Power can help confirm the software, termination and loop fit for the Emerson KJ3221X1-BA2 DeltaV M-series 8-Channel 4-20 mA HART Analog Output Card before quotation.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Software as part of fit: The running DeltaV release belongs to the spare-selection record rather than being treated as unrelated server information.
        • Installed assembly context: Carrier position and terminal identity complete the hardware evidence for the card.
        • Like-for-like repair: Matching the proven generation keeps a component failure from automatically becoming a modernization project.
        • Traceable decision: The selected spare should be linked to the installed code and project baseline in the outage record.
        • Fixed field landing: The terminal block keeps conductor destinations stable while the removable electronics are renewed.
        • Preserved control reference: The controller channel continues to point to the same documented final element after replacement.
        • Card-held conversion: Signal generation and module diagnostics return with the electronic card, not with a rewired field circuit.
        • Planned proof path: Hardware recognition, loop current and device response are separate stages of the restoration test.
        • Later hardware is a project change: A newer order family brings its own software and assembly validation instead of acting as an appearance-based substitute.
        • Terminal fit must be re-established: A platform change cannot inherit wiring compatibility solely from the old card outline.
        • Outage testing expands: Moving generations requires project, hardware and field-loop checks beyond a routine card exchange.
        • Rollback remains defined: Keeping the original code and configuration record preserves a known recovery point during modernization.
        • Earlier DeltaV analog-output positions: Restores an installed M-series current-output card tied to the legacy software baseline.
        • Existing HART output loops: Maintains compatible device communication on a documented analog final-element circuit.
        • Like-for-like outage repair: Replaces failed electronics while retaining the verified carrier and terminal assembly.
        • Controlled modernization planning: Provides the installed-generation reference against which a later output family is evaluated.
        Description
        KJ3221X1-BA2 is the earlier-generation DeltaV analog-output card used to turn controller commands into current references for valves, drives and other modulating field devices. It also keeps compatible HART device communication on the same loop used for control.

        The core value of KJ3221X1-BA2 is legacy-system continuity. It lets a plant restore an identified output position without making a later I/O generation and its software implications part of a routine card-replacement outage.
        Technical notes
        Use KJ3221X1-BA2 only after verifying that the installed DeltaV release is earlier than v10.3.1. Confirm the termination block, 24 VDC field supply, loop polarity and load before commissioning. Do not substitute a later VE-series order code without checking the software baseline and complete I/O assembly.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        The site has upgraded DeltaV, but KJ3221X1-BA2 still operates in a proven output position. Must the next outage automatically replace it with the later order family?
        No. Treat a generation change as a planned migration: verify the running project, terminal block, carrier and required regression tests. A software upgrade alone does not prove that the complete field I/O assembly should be changed.
        A control strategy requires output changes in 2 µA increments. Can KJ3221X1-BA2 provide that command resolution?
        No. Twelve-bit conversion across the normal 4–20 mA span gives a theoretical step of about 3.9 µA before accuracy and loop effects are considered. Select a higher-resolution output path for a verified 2 µA requirement.
        After a like-for-like KJ3221X1-BA2 exchange, can the work order close because calibration is stored on the card?
        No. Stored calibration avoids rebuilding the module reference, but commissioning must still verify the controller channel, terminal destination, commanded current and actual final-element response before automatic control is restored.
        The cabinet drawing and conductor labels disagree about one KJ3221X1-BA2 channel. Which record should maintenance follow?
        Neither should be trusted without reconciliation. Trace the controller assignment through the terminal to the field device, correct the approved loop record and only then reconnect; guessing can send an output command to the wrong final element.
        A terminal block has the same external shape as the one used with KJ3221X1-BA2 but a different key setting. Can it be used temporarily for testing?
        No. The key and complete terminal identity protect the field wiring from the wrong signal interface. Verify the approved card-and-terminal combination before insertion rather than bypassing the mismatch for a test.
        Can two KJ3221X1-BA2 cards on separate standard terminal blocks be configured as one redundant analog-output channel?
        No. Two independent standard positions do not create the DeltaV redundant I/O relationship. Use the approved redundant termination and paired-card architecture when output-electronics redundancy is required.
