Emerson KJ4001X1-NB1 Dual Left Extender Module
Product Introduction
The KJ4001X1-NB1 is a Dual Left Extender Module for Emerson’s DeltaV™ distributed control system. Installed adjacent to a DeltaV I/O card, it increases the module’s footprint to accommodate side-mount wiring and bus connections without interfering with neighboring slots. Its compact design ensures reliable bus continuity and signal integrity across large control cabinets.
Key Applications
-
Extending card spacing in high-density DeltaV I/O cabinets to facilitate complex wiring.
-
Enabling installation of fieldbus and FOUNDATION™ Fieldbus modules in adjacent slots.
-
Accommodating custom signal termination assemblies and retrofit adapters.
-
Simplifying maintenance by providing clear separation between modules.
-
Supporting hot-swap of DeltaV I/O cards in live systems by maintaining bus alignment.
Brand Overview
Emerson Automation Solutions is a global leader in process automation, delivering the DeltaV system—a fully integrated DCS platform renowned for its scalability, advanced control strategies, and lifecycle support across industries such as oil & gas, chemicals, power generation, and pharmaceuticals.
Product Advantages
-
Space Optimization: Creates the necessary clearance for side-mounted connectors without sacrificing slot count.
-
Reliable Bus Alignment: Machined guide rails and precision connectors maintain the integrity of the DeltaV communications bus.
-
Rugged Construction: Die-cast aluminum frame resists vibration and thermal cycling.
-
Tool-Free Installation: Spring-loaded latches allow rapid insertion and removal during cabinet modifications.
-
Minimal Footprint: Adds less than 35 mm of extra width, preserving overall cabinet density.

Frequently Asked Questions (FAQ)
Q: What is the purpose of the Dual Left Extender?
A: It creates extra clearance on the left side of a DeltaV I/O card for side-mounted connectors without widening the cabinet.
Q: Can it be installed while the system is powered?
A: Yes; the spring-loading design and offline clearance allow hot-swap of I/O cards with minimal risk.
Q: Does it affect signal integrity?
A: No; precision machined bus connectors and guide rails maintain the original signal path and shielding.
Q: What materials is it made from?
A: Die-cast aluminum with an anti-corrosion finish to withstand industrial environments.
Q: How much additional width does it require?
A: Exactly 35 mm, enabling optimal use of rack space with predictable cabinet layout.
Q: Is it compatible with all DeltaV I/O modules?
A: It fits any standard DeltaV I/O card slot without requiring adapter plates.
Q: What temperature ranges can it handle?
A: Operational from –20 °C to +60 °C and storable from –40 °C to +85 °C.
Q: How is it secured in the rack?
A: Spring-loaded latches engage automatically when inserted into the slot; no tools needed.
Q: Can multiple extenders be used in series?
A: Yes; you can deploy adjacent extenders to form wider clearance zones for multi-card assemblies.
Q: Does it support redundant bus architectures?
A: The Dual Left Extender maintains both primary and secondary bus connectors for redundant DeltaV I/O configurations.
