Product Overview

The Emerson KJ4001X1-NB1 LocalBus cable assembly, identified by order number 12P3368X022, is a horizontal dual-left interconnect designed for the DeltaV™ M-series I/O subsystem. This component enables reliable extension and alignment of LocalBus connections between adjacent DeltaV hardware assemblies, supporting stable backplane communication within distributed control system architectures.

Engineered for precision fit and electrical integrity, this LocalBus cable plays a structural and signal-routing role rather than active data processing. It ensures uninterrupted LocalBus continuity when configuring or expanding DeltaV I/O carriers, making it a critical accessory for maintaining system reliability in installed M-series environments. Although officially discontinued in 2018, it remains essential for service, retrofit, and spare-part support.

Industrial Applications

This LocalBus cable assembly is commonly used in DeltaV control cabinets where I/O carriers are mounted horizontally and require consistent LocalBus continuity. Typical use cases include system expansions, replacement of damaged interconnects, and maintenance of legacy DeltaV M-series installations across industries such as oil and gas, power generation, chemical processing, and large-scale manufacturing.

For facilities operating established DeltaV platforms, the KJ4001X1-NB1 provides a direct-fit solution that avoids reconfiguration, ensuring stable communication paths and minimizing system downtime during maintenance activities.
