Process Automation Wiring Solution — EMERSON KJ4001X1-NA1 | DeltaV Series
Where This Product Is Used
The EMERSON KJ4001X1-NA1 12P3373X012 Right Cable Extender is a field-wiring accessory engineered for use within Emerson DeltaV Distributed Control System (DCS) architectures. It is deployed wherever marshalled I/O cabinets require right-angle cable routing to maintain bend-radius compliance, reduce mechanical stress on connector pins, and optimize cable management in high-density enclosures.
Typical deployment environments include:
- Oil & Gas — upstream wellhead RTUs, midstream compressor stations, downstream refinery DCS panels
- Chemical & Petrochemical — reactor control loops, batch process automation cabinets
- Power Generation — turbine control marshalling racks, boiler management systems
- Pharmaceutical — FDA-regulated process control enclosures requiring traceable, OEM-sourced cabling
- Pulp & Paper / Water Treatment — remote I/O sub-panels with constrained cable routing space

Why Engineers Specify This Model
- OEM Right-Angle Design: The 90° connector exit eliminates sharp cable bends at the I/O card face, preserving signal integrity and extending connector service life in vibration-prone environments.
- Drop-in DeltaV Compatibility: Designed and validated by Emerson for the DeltaV I/O subsystem — no adapter plates, no field modifications required.
- Cabinet Space Optimization: Right-angle routing reduces the horizontal clearance required in front of I/O cards, enabling higher-density marshalling in constrained enclosures.
- Reduced Maintenance Downtime: OEM-matched locking mechanisms ensure secure seating, reducing nuisance disconnects during routine maintenance cycles.
- Traceability: Dual part-number marking (KJ4001X1-NA1 / 12P3373X012) supports asset management and spare-parts documentation in regulated facilities.

Application-Specific FAQ
Q: Is KJ4001X1-NA1 the same as 12P3373X012?
A: Yes. These are dual Emerson part numbers for the same component — KJ4001X1-NA1 is the primary catalog number; 12P3373X012 is the manufacturing/drawing reference. Both are accepted in procurement systems.
Q: Which DeltaV I/O cards does this cable extender support?
A: This extender is designed for the DeltaV S-Series and M-Series I/O subsystem connector interface. Verify compatibility with your specific card generation using the Emerson DeltaV Hardware Reference Manual or contact our team.
Q: Can this be used in SIL-rated safety loops?
A: The cable extender is a passive wiring accessory. SIL suitability depends on the overall loop design and the SIL rating of the connected I/O card. Consult your functional safety engineer and the Emerson DeltaV SIS documentation.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC and inspection report can be provided upon request for regulated industries (pharmaceutical, nuclear, oil & gas).
Q: What is the lead time if out of stock?
A: Typical procurement lead time from our supplier network is 5–15 business days. Contact us for real-time availability.
