Selection Guide
Use the following criteria to confirm the KJ3002X1-BC1 is the right module for your application:
- Signal type: Requires 4–20 mA or 1–5 V analog inputs → ✅ KJ3002X1-BC1 is suitable
- HART requirement: If HART device management is needed → consider KJ3221X1-BA1 instead
- Channel count: Need more than 8 channels per slot → consider KJ3002X1-BD1 or multi-module carrier layout
- SIL rating: SIL 2/3 safety loop → verify with Emerson SIS documentation; dedicated SIS modules may be required
- DeltaV version: Running v9.x or earlier → confirm firmware compatibility before ordering
- Revision matching: Mixing BC1 with BA1/BB1 revisions in redundant pairs is generally supported but should be validated in your specific DeltaV version release notes

Replacement & Compatibility FAQ
Q: Can I replace KJ3002X1-BC1 with KJ3002X1-BA1 without reconfiguring DeltaV?
A: In most cases yes — the module type is recognized identically by DeltaV. However, confirm your DeltaV version supports the BA1 revision and check for any applicable Emerson Product Data Sheets or Field Change Notices.
Q: Is the KJ3002X1-BC1 compatible with DeltaV SIS (Safety Instrumented System)?
A: The standard KJ3002X1-BC1 is not a certified SIS module. For SIL-rated loops, use Emerson’s dedicated SIS I/O modules (e.g., KJ3002X1 SIS variants) and consult your functional safety engineer.
Q: What is the difference between 12P0681X072 and other 12P0681X0xx reference numbers?
A: The 12P0681X0xx suffix denotes the manufacturing revision or regional variant. X072 is the standard commercial release. Contact Konmask for cross-reference verification if you have a different suffix.
Q: Can this module be used outside of a DeltaV system?
A: No — the KJ3002X1-BC1 is designed exclusively for the DeltaV backplane architecture and cannot be used as a standalone or third-party DCS module without significant hardware adaptation.
Q: Do you offer exchange / repair services?
A: Yes. Konmask partners with certified repair facilities for DeltaV I/O modules. Contact us with your failed unit details for a repair quotation.
