Technical Specifications & Performance Details
Bus Architecture: What is the primary role of the "1-Wide Carrier Extender Right" in a DeltaV™ layout?
The KJ4001X1-NA1 serves as the physical and electrical bridge for the LocalBus. It extends the I/O backplane to the right, allowing for modular expansion of I/O carriers. By using this "1-wide" footprint, engineers can bridge separate carrier segments while maintaining signal integrity across the horizontal bus without consuming excessive cabinet rail space.
Current Capacity: How does the 8A rating at 12 VDC impact power distribution planning?
The extender is rated for a substantial 8 Amps. This represents the pass-through capacity for the LocalBus power rail. When calculating your power budget, ensure that the upstream power supply can handle the cumulative draw of all downstream I/O modules connected via this extender, especially in high-density analog output configurations.
Environmental Resilience: What does the ISA-S71.04 Class G3 rating signify for harsh deployments?
The G3 rating (Harsh) means this extender is specifically treated to resist atmospheric corrosion. In environments like pulp and paper mills or petrochemical refineries where sulfur and chlorine levels are elevated, the G3-compliant conformal coating protects the 12P3373X022's circuitry from "whisker" growth and contact failure that would typically damage standard commercial hardware.
Thermal Dynamics: Can the module withstand -40°C to +70°C without active cooling?
Yes. The wide-temperature specification is designed for non-climate-controlled remote instrument enclosures (RIEs). However, at the +70°C ceiling, account for the 8A power throughput. High current generates internal resistive heat; in high-ambient setups, ensure at least 2 inches of clearance for convective airflow to prevent localized hotspots on the carrier.
Mechanical Stress: Why is the 10g shock rating critical for this specific component?
The KJ4001X1-NA1 is a structural link. A 10g (11ms half-sinewave) shock rating ensures that the LocalBus connection remains seated during high-impact events, such as nearby heavy machinery cycling or seismic activity. It prevents "nuisance trips" caused by momentary contact chatter in the bus connectors.
Orientation Constraints: Is the "Right" extender interchangeable with a "Left" version?
No. The "Right" designation (12P3373X022) is specific to its mechanical keying and bus termination logic. The internal bus connectors are polarized to extend the signal path in one direction only. Attempting to force a configuration or reverse the logic will result in a physical mismatch and potential damage to the backplane pins.
Vibration Tolerance: How does the 1mm peak-to-peak spec translate to offshore or marine use?
The module is tested for 0.7g from 13.2 to 150Hz, which covers typical vibration frequencies found on offshore platforms or near large rotating equipment. This ensures that the extender won't suffer from fatigue-induced solder joint fractures or "fretting corrosion" on the bus pins over long-term exposure.
Footprint Optimization: What are the implications of the "1-Wide" sizing?
The 16.8 x 4.2 x 6.8 cm dimensions are optimized for high-density DIN-rail mounting. The 4.2 cm width (1-wide) allows for precise system scaling. It is essentially the "narrowest" possible bridge, ensuring that the bulk of your enclosure width is dedicated to active I/O modules rather than passive bus infrastructure.
Humidity Mitigation: How does the "Non-Condensing" 5-95% spec affect cabinet design?
While the module handles up to 95% humidity, condensation is the enemy. If the enclosure transitions through the dew point (common in tropical or outdoor sites), moisture on the bus connectors can cause 12VDC shorts. We recommend using an enclosure heater or desiccant system in any environment where rapid temperature swings are expected.
Logistics & Verification: Why is the origin USA but the shipment from Xiamen?
This is standard for global Emerson lifecycle management. The KJ4001X1-NA1 is engineered and manufactured to USA quality standards (12P3373X022), but regional distribution hubs (like Xiamen) are used to stage critical spares for the APAC and global markets. When verifying the unit, always check that the Part Number (12P3373X022) matches the "NA1" model code to ensure you have the correct G3-rated hardware.
