Product Introduction (Rotation Engine)
A DeltaV I/O rack only expands cleanly when the local bus is extended with the correct cable assembly. The EMERSON KJ4001X1-NA1 12P3373X012 is a Horizontal LocalBus dual right cable extender for the Emerson DeltaV Series 2 I/O platform. It provides the right-side local-bus connection between adjacent carriers, allowing the I/O rack to maintain continuous communication across multiple carrier positions.
This is a passive cable/connector assembly, not a power supply, controller, or I/O module. It is typically used during rack expansion, carrier replacement, cabinet reconfiguration, or commissioning when the local bus must be extended to the right of an existing carrier. For system integrators and plant maintenance teams, having a verified spare extender cable helps avoid last-minute delays when expanding or restoring DeltaV I/O racks.

Key Selling Points & Differentiators
- Direct replacement for DeltaV horizontal right-side local-bus extension applications.
- Dual-cable assembly supports full local-bus continuity across adjacent carriers.
- Passive design means no firmware, no configuration, and no separate power supply.
- Factory-sealed surplus lowers DOA risk compared with pulled used extender cables.
- 1-year functional warranty covers manufacturing defects and DOA failures.
- Not recommended as a left-side extender, vertical extender, power cable, I/O module, or CHARMs FTA replacement.
Quality Transparency SOP (DYNAMIC GENERATION)
- Visual inspection: Check cable jackets, connector housings, locking clips, labeling, and strain relief for damage or deformation.
- Part verification: Confirm model KJ4001X1-NA1, alternate P/N 12P3373X012, and revision REV C against the packing list.
- Connector inspection: Verify pin alignment, connector integrity, and absence of bent or corroded contacts.
- Fitment check: Confirm proper mating with the compatible DeltaV Series 2 carriers before final packing.
- Continuity test: Check local-bus pin-to-pin continuity to confirm clean signal paths across both cable assemblies.
- Final packing: Anti-static bag, moisture barrier, shock-safe boxing, and photo-documented QA.
Technical Risk Avoidance (DYNAMIC GENERATION)
❗ Do not install KJ4001X1-NA1 as a left-side extender. The -NA1 is a right-side dual extender; the left-side counterpart is KJ4001X1-NB1.
❗ Confirm carrier compatibility before installation. Local-bus extender cables must match the installed DeltaV Series 2 carrier family.
❗ Do not use this assembly as a power cable, I/O module, or logic solver. It only extends local-bus communication between carriers.
❗ Verify rack topology before adding extenders. Exceeding the allowed local-bus segment length or carrier count can cause communication faults.
Buyer’s FAQ
Is this a genuine OEM part?
Yes. This is an OEM Emerson DeltaV component supplied as new surplus / factory sealed. We do not rebrand or relabel third-party equivalents.
Is it new or refurbished?
Listed as New Original (New Surplus) / Factory Sealed unless otherwise stated. Any deviation in condition or revision will be disclosed before shipment.
Can I use it as a direct replacement?
Yes, for DeltaV horizontal right-side local-bus extension applications. Confirm the carrier type, rack orientation, and extender position first.
What is the difference between KJ4001X1-NA1 and KJ4001X1-NB1?
KJ4001X1-NA1 is the right-side dual extender cable. KJ4001X1-NB1 is the left-side dual extender cable. They are not interchangeable without confirming rack layout.
What warranty is included?
A 1-year functional warranty covers manufacturing defects and DOA failures. Damage from incorrect installation, misapplication, or improper carrier mating is not covered.
