KJ3222X1-EA1 is the complete Emerson DeltaV M-series marking for a Redundant AI Terminal Block. Emerson ATEX Instruction Sheet ATEX246 identifies the exact model and specifies 30 VDC at 200 mA input power, -40 to +70 deg C ambient operation, and the required removal, maintenance, and hazardous-area conditions. The current M-series ordering information describes a redundant standard I/O termination block for analog input service; compatibility with a legacy KJ3222X1-EA1 installation must be verified against the paired card, carrier, revision, and keying.

Model Verification

Exact marking
KJ3222X1-EA1

Official identity
Redundant AI Terminal Block

Evidence to match
Nameplate, revision, paired card, carrier, and keying

Compatibility

I/O function
Redundant analog input termination

System family
DeltaV M-series Traditional I/O

Selection check
Verify the paired analog input card, terminal keying, carrier, revision, and DeltaV version before replacement

Installation

De-energize
Do not remove or insert the unit while system power is energized

Mechanical match
Confirm the carrier position, paired redundant AI card, and rotary key setting before installation

Area procedure
Follow Emerson document 12P2046 and the applicable DeltaV hardware installation manual for hazardous areas

Procurement Checks

Identity
Require a current, legible photo showing the complete KJ3222X1-EA1 marking

Engineering match
Confirm 30 VDC at 200 mA, redundant AI service, paired card, carrier, keying, and area approvals

Condition evidence
Request photos of the label, housing, connector, terminals, screws, seals, and packaging before payment

FAQ

Q1. How can a buyer verify that the quotation is for exactly KJ3222X1-EA1?

Require a clear current nameplate photo showing the complete KJ3222X1-EA1 marking. Match the revision, paired redundant analog input card, carrier position, rotary keying, and terminal layout to the installed DeltaV system.

Q2. How can New, Used, or Refurbished condition be distinguished for KJ3222X1-EA1?

Ask for high-resolution photos of the label, enclosure, connector, field terminals, screws, keying parts, seals, and packaging. Connector wear, tool marks, replaced labels, cleaned terminals, or mixed revisions require a written condition explanation.

Q3. How should supplier legitimacy be checked before purchasing KJ3222X1-EA1?

Verify the registered company name, physical contact information, domain, banking beneficiary, written quotation, traceable references, and inspection or return terms. Require a time-stamped photo tying the exact KJ3222X1-EA1 unit to the quotation.

Q4. Which specifications should an engineer confirm before ordering KJ3222X1-EA1?

Confirm that the required component is a redundant analog input terminal block, not an analog input card. Check the 30 VDC at 200 mA rating, paired card, carrier, keying, revision, -40 to +70 deg C ambient range, and required approvals.

Q5. What physical evidence should be requested before payment?

Request front, side, connector, and terminal photos; close-ups of the complete model and revision label; the rotary key setting; terminal condition; packaging; and a dated image or video showing the same unit identified in the quotation.

Q6. Can a similar suffix or a current ordering code replace KJ3222X1-EA1?

Not automatically. A BA suffix identifies a card rather than this EA terminal block, and current VE ordering codes must not be assumed interchangeable. Replacement requires engineering verification of function, carrier, paired card, keying, revision, and DeltaV version.
