The Emerson KJ4002X1-BF2 (12P3866X012) is a high-speed Bus Extender Cable for the DeltaV DCS. Designed to link I/O carriers, this shielded cable ensures reliable data transmission and power distribution across expanded system nodes, providing a robust solution for modular control architecture.
The Emerson KJ4002X1-BF2, identified by part number 12P3866X012, functions as a high-speed Bus Extender Cable within the DeltaV Distributed Control System (DCS). This specialized hardware enables the expansion of the local I/O bus across multiple sub-bases or carriers within a single system node. By facilitating the seamless transfer of data and power between I/O modules, the KJ4002X1-BF2 allows engineers to scale their control architecture without degrading signal integrity or increasing communication latency.
This bus extender cable manages the critical interconnection between localized I/O clusters. Because the DeltaV system relies on a modular “plug-and-play” philosophy, the KJ4002X1-BF2 provides a secure, physical link that maintains the continuity of the redundant bus signals. Furthermore, the cable features high-density, multi-pin connectors that include locking mechanisms to prevent accidental disconnection in high-vibration industrial environments.
To ensure consistent performance, the cable is manufactured with heavy-duty shielding to mitigate the effects of electromagnetic interference (EMI). Since the 12P3866X012 is a factory-terminated assembly, it eliminates the wiring errors often associated with manual terminations. Moreover, the bus extender supports the automatic addressing capabilities of the DeltaV controller, ensuring that any I/O modules connected via the extension are immediately recognized by the system software.
