Selection Guide
Use the following decision framework to determine whether the KJ2003X1-BA2 is the right module for your application:
- Step 1 — Identify your DeltaV version: Confirm your system software version in DeltaV Explorer before ordering.
- Step 2 — Check carrier revision: The KJ2003X1-BA2 requires a compatible DeltaV carrier; verify the carrier part number.
- Step 3 — Assess redundancy requirements: If your system uses controller redundancy, confirm the paired module revision matches.
- Step 4 — Evaluate replacement vs. upgrade: If your current module is KJ2003X1-BA1, a direct swap to BA2 is typically safe; upgrading to CA1 may require a DeltaV version update.
- Step 5 — Contact Konmask: Send your system details to [email protected] for a pre-purchase compatibility check at no charge.
