Product Overview

KJ3221X1-BA1 is an Emerson DeltaV M-series Series 2 eight-channel 4-20 mA HART analog output card.

The current official PDS specifies a 1 to 23 mA full output range, 0.25 percent span accuracy, 12-bit resolution and output compliance of 20 mA at a 21.6 VDC supply into a 700 ohm load.

The exact instruction sheet identifies 12 VDC LocalBus power at 150 mA, 24 VDC field power at 300 mA, 23 mA per-channel field circuits, A4 keying and an IP20 component rating.

Applications & Features

Eight current outputs

Eight 4-20 mA channels support final-control devices in DeltaV applications.

HART capability

The complete model supports HART communication with compatible field devices.

Defined analog performance

The PDS specifies 0.25 percent span accuracy and 12-bit resolution.

Redundant termination option

The ordering information lists standard and redundant terminal-block arrangements for the eight-channel HART AO interface.

Connections

Analog outputs	Eight 4-20 mA HART channels with a 1 to 23 mA full range.
LocalBus	12 VDC nominal; 100 mA typical and 150 mA maximum.
Bussed field power	24 VDC at 300 mA.
Channel circuit	24 VDC at 23 mA maximum per channel on the exact instruction sheet.
Terminal block	Use an A4-keyed standard, fused, redundant or approved 16-pin mass-termination arrangement.
Load compliance	Confirm the loop load remains within the published 700 ohm compliance at 21.6 VDC and 20 mA.

Installation

01 - Verify the complete suffix

Match KJ3221X1-BA1 on the label, quotation and dated photos; confirm eight-channel HART analog output identity.

02 - Confirm A4 keying

Use only compatible A4-keyed terminal hardware.

03 - Check each loop

Verify 4-20 mA output scaling, HART device compatibility, polarity and load resistance.

04 - Check power budgets

Confirm 12 VDC LocalBus power, 24 VDC bussed field power and the 23 mA per-channel field-circuit limit.

05 - Follow hazardous-area rules

De-energize non-sparking circuits and follow ATEX135 and 12P2046 before removal, insertion or terminal-block work.

Environment

Ambient temperature

-40 to +70 degrees C on the exact instruction sheet.

Storage temperature

-40 to +85 degrees C in the current M-series Traditional I/O data sheet.

Protection

IP20 component; install in the enclosure required by the site and certification.

Relative humidity

5 to 95 percent, non-condensing.

Shock

10 g half-sine wave for 11 ms.

Airborne contaminants

ISA-S71.04-1985 Class G3 with conformal coating.

Maintenance

No user-serviceable parts; calibration is not required unless the exact card documentation states otherwise.

FAQ

Q1. How can the exact quoted KJ3221X1-BA1 be verified?

Match KJ3221X1-BA1 on the product label and current photos. Confirm eight 4-20 mA HART outputs and A4 terminal-block keying.

Q2. How can New, Used or Refurbished condition be distinguished?

Request date-marked photos of the label, A4 keying, front indicators, contacts, terminal interface and packaging. Look for loop-connection wear, repairs or replaced identification labels.

Q3. How should supplier legality and reliability be checked?

Verify the legal entity, registered address, payment beneficiary and traceable sales contact. The offer must state Emerson, KJ3221X1-BA1, HART AO card, condition and quantity.

Q4. Which specifications must engineering confirm before purchase?

Confirm eight 4-20 mA outputs, HART support, 12-bit resolution, 0.25 percent accuracy, A4 keying, field-power limits, load compliance and termination type.

Q5. What physical evidence should be requested before payment?

Ask for a dated image set showing the complete label, serial data, A4 key position, front indicators, rear contacts, terminal interface and original packaging.

Q6. Can a similar HART analog card replace KJ3221X1-BA1?

No. KJ3221X1-BA1 is an analog output card with A4 keying. An analog input card or a card with different keying is not an automatic substitute because signal direction and termination differ.
