The Emerson KJ4001X1-NB1 12P3368X022 is a horizontal LocalBus dual left cable for DeltaV systems. It supports 12VDC at 8A and provides redundant bus expansion between I/O carriers. This ruggedized component ensures reliable data and power distribution in demanding DCS environments.
The KJ4001X1-NB1 serves as a high-capacity bus extender for the Emerson DeltaV M-series platform. This component facilitates the physical and electrical connection between adjacent horizontal I/O carriers. Specifically, the “Dual Left” configuration enables redundant communication paths across the local bus architecture. It ensures that the controller maintains constant contact with all distributed I/O modules. By bridging these segments, the cable provides a stable backbone for complex automation hardware. This connectivity is essential for maintaining system integrity in large-scale process control environments.
