- Diagnostic Reporting: Built-in open-wire, over-range, and under-range detection with DeltaV alarm integration
System Architecture & Signal Flow
The KJ3222X1-BK1 mounts directly onto a DeltaV S-Series I/O carrier. Field transmitters (4–20 mA HART) connect to the carrier terminal block. The module conditions and digitizes each analog signal at 16-bit resolution, then transmits process values to the DeltaV controller via the S-Series I/O bus. HART secondary variables and device diagnostics are simultaneously passed to the DeltaV Asset Management Solution (AMS) for predictive maintenance workflows.
Signal path: Field Device → Carrier Terminal → KJ3222X1-BK1 ADC → DeltaV S-Series Bus → Controller → DCS Historian / AMS

Technical FAQ
Q: Is the KJ3222X1-BK1 compatible with DeltaV M-Series controllers?
A: No. This card is designed exclusively for the DeltaV S-Series I/O subsystem. For M-Series compatibility, refer to the KJ3221X1 series.
Q: Can this module be used in SIL-rated safety loops?
A: The standard KJ3222X1-BK1 is not SIL-certified. For safety instrumented systems, Emerson offers dedicated SIS I/O modules. Contact us for SIS-rated alternatives.
Q: What HART revision does this card support?
A: The module supports HART 5 and HART 6. HART 7 compatibility depends on the DeltaV controller firmware version — consult your DeltaV system administrator.
Q: Do you provide a Certificate of Conformance?
A: Yes. A CoC with serial number, test date, and technician sign-off is available for all tested units upon request.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume pricing is available for orders of 5 units or more.
