Selection Guide
Use the following criteria to confirm the correct cable extender for your DeltaV system:
- Step 1 – Identify your controller series: S-series or M-series determines carrier type.
- Step 2 – Check cable run length: KJ4001X1-NB1 supports standard extension distances; consult Emerson documentation for maximum cable length.
- Step 3 – Verify revision compatibility: Match the -NB1 revision suffix to your existing carrier and I/O module revisions.
- Step 4 – Confirm part number: Cross-reference 12P3368X012 against your BOM or Emerson spare parts list.
- Step 5 – Contact Konmask: Our team can validate compatibility with your specific DeltaV system configuration.
