KJ4001X1-NA1 | Emerson DeltaV Dual Right Cable Extender

Product Overview

The Emerson KJ4001X1-NA1 functions as a high-integrity Dual Right Cable Extender within the DeltaV™ Distributed Control System (DCS). This module facilitates the physical expansion of the LocalBus across multiple carriers, allowing for flexible rack configurations and extended I/O layouts. It maintains signal continuity and power distribution for dense automation architectures. We supply this unit as 100% Brand New and Original, ensuring your control system expansion meets factory-certified performance and safety standards.

Technical Specifications

The KJ4001X1-NA1 incorporates rugged electrical paths and environmental hardening to ensure continuous bus communication in demanding industrial cabinets.

Engineering Advantages

• Extended LocalBus Capacity: The KJ4001X1-NA1 extends the 12 VDC LocalBus while supporting a high current throughput of 8A. This allows engineers to build out large-scale I/O subsystems across multiple DIN rail rows without suffering from voltage drops or signal degradation.

• Corrosive Atmosphere Protection: This extender carries an ISA-S71.04 Class G3 rating. The factory-applied coating shields the internal copper traces and connectors from corrosive gases like Hydrogen Sulfide ($H_2S$) and Sulfur Dioxide ($SO_2$), preventing the intermittent bus faults common in refineries and chemical plants.

• Extreme Thermal Resilience: A wide operational window of -40°C to 70°C allows for installation in remote instrument enclosures (RIEs) subject to extreme arctic or desert conditions. This eliminates the need for supplemental HVAC equipment within the control cabinet.

• Mechanical Stability: The module withstands 10g of shock and survives vibration levels up to 150Hz. This durability ensures that the bus connection remains physically secure even when mounted on process skids subject to mechanical resonance from pumps or turbines.

• Dual-Path Redundancy Support: The "Dual" architecture provides redundant signal paths for the bus extension. This layout minimizes the risk of a total system shutdown if a single physical connection experiences stress or damage during maintenance.

FAQs

Q: Is this KJ4001X1-NA1 unit a "New-Surplus" or refurbished item?

A: No. We supply only 100% Brand New and Original Emerson hardware. Every unit ships in its original factory packaging with verified serial numbers, ensuring full compliance with DeltaV system warranties and technical specifications.

Q: Does the KJ4001X1-NA1 require a separate power supply for the extension?

A: No. The extender draws its operating power and passes the 8A current directly from the DeltaV LocalBus. However, you must ensure your primary LocalBus power supply (such as the KJ4001X1-BA3) provides sufficient amperage for the total number of modules across the extended segments.

Q: What is the specific role of the "Right" orientation in this model?

A: The "Right" designation refers to the physical orientation and pin-out logic for extending the bus from the right-hand side of a DeltaV carrier. This allows for clean cable management and logical flow when jumping from one DIN rail row to the next in a standard cabinet layout.

Q: How does the IP20 rating impact installation?

A: The IP20 rating indicates protection against solid objects larger than 12.5mm but provides no protection against water. You must install the KJ4001X1-NA1 inside a properly rated NEMA or IP-certified industrial enclosure to protect the bus connections from liquid ingress and heavy dust.
