Emerson KJ4001X1-NB1 12P3368X012 DeltaV M-Series Horizontal LocalBus Dual Left Cable Extender

The Emerson KJ4001X1-NB1 (12P3368X012) is a DeltaV M-series Horizontal LocalBus Dual Left Cable Extender. It facilitates high-speed communication between I/O carriers in a DCS environment. This 12V DC module supports up to 8A and is designed for reliable, redundant bus expansion in space-constrained industrial cabinets.

Product Description

The Emerson KJ4001X1-NB1 functions as a primary connection interface for the DeltaV M-series I/O subsystem. This Horizontal LocalBus Dual Left Cable Extender allows the control system to bridge communication signals between separate horizontal carrier rows. By integrating this module, operators can extend the reach of the local bus architecture to the left side of the cabinet, ensuring that the DCS controller maintains a high-speed data link with all connected I/O components.

Consequently, this extender plays a vital role in maintaining system synchronization. It carries both logic signals and the necessary power to drive the I/O bus, supporting a standardized 12 VDC supply at up to 8 A. Because the hardware utilizes a “dual” cable configuration, it provides the necessary redundancy paths required for high-availability process environments where downtime is not an option.

Engineers favor the KJ4001X1-NB1 for its streamlined installation process. The unit mounts directly to the end of an M-series carrier, transforming the terminal point into an active gateway. Moreover, the durable housing resists the thermal and electromagnetic interference typically found in heavy industrial settings, which protects the integrity of the process data as it travels across the local bus segments.
