Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or functional equivalents. Always verify electrical, firmware, and bus compatibility before substitution.
- EMERSON KJ3002X1-BA1 — Earlier revision of the same RTD input module; functionally equivalent, check firmware compatibility.
- EMERSON KJ3002X1-BC1 — Mid-revision variant; same channel count and sensor support.
- EMERSON KJ3002X1-BE1 — Alternate approved revision; confirm with DeltaV system version.
- EMERSON KJ3002X1-BG1 — Later revision with potential firmware enhancements; backward compatible in most DeltaV versions.
- EMERSON KJ3002X1-BH1 — Current production revision (verify availability); drop-in replacement in DeltaV S-series.
- Third-party RTD Input Modules — Some third-party DeltaV-compatible I/O modules exist; however, Emerson does not officially certify non-OEM modules for DeltaV. Use with caution and consult your system integrator.
Note: Revision letters (BA1, BC1, BF1, BG1, BH1) indicate hardware/firmware revisions. Functional differences are typically minor, but always cross-reference with your DeltaV system version and Emerson’s compatibility matrix.

Selection Guide
Use the following criteria to confirm the KJ3002X1-BF1 is the right module for your application:
- Step 1 — Confirm DCS Platform: Verify your system is DeltaV S-series or M-series. This module is not compatible with other Emerson platforms (PROVOX, RS3, Ovation).
- Step 2 — Identify Sensor Type: Confirm your field sensors are RTD type (PT100, PT200, Ni100, etc.). For thermocouple inputs, consider the KJ3001X1 series instead.
- Step 3 — Count Input Channels: KJ3002X1-BF1 provides 8 RTD input channels. For higher channel density, evaluate multi-channel I/O solutions or additional modules.
- Step 4 — Check Revision Compatibility: Confirm your DeltaV version supports the BF1 revision. Older DeltaV versions may require earlier revisions (BA1, BC1).
- Step 5 — Verify Carrier Slot Availability: Ensure your I/O carrier has an available slot. The module occupies one standard DeltaV I/O slot.
- Step 6 — Hazardous Area Requirements: If installing in a classified hazardous area, confirm the module’s certifications meet your area classification (Zone 2 / Div. 2 or higher).

Replacement & Compatibility FAQ
Q: Can I replace KJ3002X1-BF1 with KJ3002X1-BH1 (a newer revision)?
A: In most DeltaV installations, yes. Newer revisions are generally backward compatible. However, always verify with your DeltaV system version and Emerson’s compatibility matrix before substitution in a live system.
Q: Is KJ3002X1-BF1 compatible with DeltaV SIS (Safety Instrumented System)?
A: No. DeltaV SIS uses dedicated SIS I/O modules. The KJ3002X1-BF1 is a standard DeltaV I/O module and must not be used in SIS applications.
Q: Can this module be used with third-party DCS systems?
A: No. The KJ3002X1-BF1 communicates via Emerson’s proprietary DeltaV I/O bus and is not compatible with other DCS platforms (Honeywell, ABB, Siemens, Yokogawa, etc.).
Q: What is the difference between part number KJ3002X1-BF1 and reference number 12P1732X042?
A: KJ3002X1-BF1 is the Emerson catalog/ordering part number. 12P1732X042 is the internal reference/revision number. Both refer to the same physical module.
Q: Do you provide a certificate of conformance (CoC) or test report?
A: Yes, documentation is available upon request for most units. Please specify your requirements at the time of inquiry.
Q: Can I use PT1000 sensors with this module?
A: Yes, the KJ3002X1-BF1 supports PT1000 sensors in addition to PT100, PT200, PT500, Ni100, Ni120, and Cu10.
