More Information

Overview Manuals Applications Communication Operating Environment Certifications

Features:

  • Provides eight 4–20 mA HART analog output channels in the DeltaV M-Series form factor.
  • Optically isolates each channel from the system and applies a 1500 VDC factory isolation test.
  • Supports simplex or redundant I/O architecture with the appropriate Series 2 terminal hardware.
The current ordering configuration is KJ3221X1-BA3, the Series 2 M-Series eight-channel HART analog output card.

It converts DeltaV control commands into field current for compatible valve positioners, actuators, and other intelligent analog devices while retaining HART access.

Before commissioning, confirm DeltaV v10.3.1 or later, the A4 terminal key, loop loading, field power, redundancy design, and hazardous-area approval.

Availability is subject to Apter Power inventory and sourcing confirmation.
Verified resources for Emerson KJ3221X1-BA3: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.
  • Modulates control valves, positioners, and other 4–20 mA final control elements in continuous process loops.
  • Supports intelligent field-device integration in chemical, oil and gas, water, power, and general process-control systems.
  • Fits critical-loop designs that use the supported M-Series redundant terminal-block architecture.
  • Provides HART pass-through for compatible intelligent instruments and AMS Device Manager access.
  • Makes HART device variables and status available to configured DeltaV control functions.
  • Communicates through the M-Series I/O interface and controller architecture rather than as a standalone network device.
  • Operates across the documented ambient temperature range of −40 to +70°C.
  • Supports 5 to 95% relative humidity when the atmosphere remains non-condensing.
  • Uses conformal coating for ISA-S71.04-1985 Class G3 airborne-contaminant conditions.
  • Carries the II 3G Ex ec [ic] IIC Gc marking under the documented ATEX configuration.
  • Includes IECEx and UKEX component certifications for the identified hazardous-area version.
  • Is evaluated for listed Class I Division 2 and Class I Zone 2 installations under applicable FM approvals.
Description
KJ3221X1-BA3 is the Emerson DeltaV M-Series Series 2 analog output card with eight 4–20 mA HART channels for process-control field loops.

Each channel is optically isolated from the system, with 12-bit output resolution, 0.25% span accuracy across the operating range, and HART communication for compatible intelligent instruments.

The BA3 configuration requires DeltaV v10.3.1 or later. Verify the A4 terminal-block key, loop power, redundancy arrangement, hazardous-area approval, and installed software before replacement.

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.
Does KJ3221X1-BA3 support earlier DeltaV software releases?
The BA3 ordering configuration requires DeltaV v10.3.1 or later; Emerson directs earlier releases to the BA2 configuration.
Can KJ3221X1-BA3 be used in a redundant I/O arrangement?
Yes. Series 2 HART I/O cards support simplex or redundant use when installed with the correct redundant terminal block and project configuration.
What should be checked if a HART device does not communicate through KJ3221X1-BA3?
Check loop wiring, field power, HART enablement, device compatibility, and the AMS Device Manager communication path before replacing the card.
Why must the complete KJ3221X1-BA3 suffix be supplied for replacement?
The suffix identifies the Series 2 ordering configuration and helps confirm software, termination, and approval compatibility.
Can KJ3221X1-BA3 be exchanged without reviewing the terminal block?
No. Confirm the A4 key and the installed simplex or redundant terminal block before exchanging the card.
Where can buyers obtain KJ3221X1-BA3 documentation and availability?
Use the verified datasheet in the Manuals tab and provide the complete model, quantity, destination, and system revision when requesting a quotation.
