Emerson KJ4001X1-NA1 Dual Right Cable Extender for DeltaV
Product Summary
The KJ4001X1-NA1 is a Horizontal LocalBus Dual Right Cable Extender from Emerson. This module extends DeltaV system I/O carriers in hazardous areas. It delivers reliable performance with a robust power supply and wide environmental tolerances. Engineers trust this unit for critical process control expansions.
Theme A: Product Procurement & Buyer Guide
Procurement managers must match the KJ4001X1-NA1 to specific application needs. This unit carries a Nemko No. 02ATEX431U certification for Zone 2. It is approved for Hazardous Atmosphere II 3 G with an EEx nA IIC T4 rating. This makes it ideal for chemical and refinery environments.
The module draws LocalBus power at 12 VDC and supports up to 8 Amps. This power specification ensures stable operation for connected I/O carriers. You must verify your system power budget before ordering. The unit connects with a dual right cable configuration for flexible layout.

Application engineers should note the strict installation rules. The total cable length for all carriers and extenders must not exceed 6.5 meters. You must route interconnecting cables through conduit between enclosures. This requirement prevents signal degradation and ensures safety compliance.
The unit operates in extreme temperatures from -40 to 70 degrees Celsius. This range suits outdoor installations or unheated process areas. It also withstands shock up to 10g for 11 milliseconds. Vibration tolerance is 1mm peak-to-peak from 5 to 16Hz. These specs guarantee reliability in heavy industrial settings.
Environmental protection includes an IP20 rating for indoor use. The module resists airborne contaminants classified as ISA-S71.04 Class G3. Relative humidity tolerance spans 5 to 95% non-condensing. These factors protect internal electronics from corrosion and failure.
Always check the product label for the serial number and manufacture date. This data is critical for traceability and warranty claims. Refer to document 12P2046 for specific Zone 2 installation instructions. Following these guidelines ensures safe and compliant deployment.

Theme B: Step-by-Step User & Installation Guide
Begin installation by de-energizing the entire system power. The KJ4001X1-NA1 cannot be removed or inserted with power applied. You must cut power before disconnecting any carriers or LocalBus Extender cables. This step prevents electrical shock and equipment damage.
Mount the extender in a suitable enclosure with an IP20 rating. Ensure the area is known to be non-hazardous before unplugging the unit. Do not exceed the maximum cable length of 6.5 meters for the entire bus. Plan your layout carefully to stay within this limit.
Connect the dual right cables to the adjacent I/O carriers. Use only approved conduit for interconnecting cables between different enclosures. This practice maintains the integrity of the hazardous area protection. Secure all connections tightly to avoid intermittent faults.
Do not attempt to disassemble the unit for any reason. The KJ4001X1-NA1 contains no user-serviceable parts inside. Calibration is not required for this component. If a fault occurs, replace the entire module with a certified spare.

Follow the manual titled "Installing Your DeltaV Automation System" for complete guidance. This document covers all aspects of system integration. Proper installation ensures long-term performance and safety compliance. Always double-check the power is off before handling cables.
