Emerson KJ3221X1-BA1 8-Channel 4–20 mA HART Analog Output Card
A Series 2 DeltaV analog-output card with eight 4–20 mA HART channels and redundancy support.
Overview
Emerson KJ3221X1-BA1 is a DeltaV M-Series Series 2 analog output card providing eight 4–20 mA channels with HART communication.
The card is redundant-capable within the documented DeltaV arrangement. LocalBus, bussed field and per-channel field-circuit power values must be checked together with the terminal-block key position.
Removal and insertion restrictions depend on the area classification and field-circuit condition. The unit has no user-serviceable parts and does not require calibration.
Specifications
Features
Eight HART-capable loops
Each channel delivers the documented 4–20 mA analog-output function with HART support.
Redundancy-ready architecture
The card can participate in the approved Series 2 redundant arrangement.
Defined power budget
LocalBus, bussed field and per-channel circuit values provide a clear panel-load boundary.
Mechanical key control
A4 keying helps prevent pairing with the wrong terminal-block execution.
Applications
Final-control outputs
Driving compatible 4–20 mA valve positioners, converters or other receiving devices with HART access.
Redundant process loops
Supporting high-availability output service in the approved DeltaV redundant topology.
Controlled card exchange
Replacing the same AO identity while retaining channel mapping, HART devices and terminal-block keying.
Lifecycle
Archive
Save all eight loop assignments, HART identities, output ranges, fail actions and redundancy state.
Exchange
Apply the documented power and area restrictions and verify A4 terminal-block keying.
Prove
Stroke or simulate each loop under the approved procedure, verify HART communication and confirm redundancy transfer.
