Emerson KJ4002X1-BF2 Extender Cable

The Emerson KJ4002X1-BF2, also cataloged as the KJ4002X1-BF2 Extender Cable for Horizontal Carriers, operates as a dedicated hardware component for high-density signal propagation, backplane bus expansion, and mechanical link flexibility within DeltaV distributed control system architectures. Configured for high-density instrumentation tracking, the cable assembly provides direct electrical bridge continuity to link adjacent horizontal I/O carriers over a fixed distance profile.

Hardware Specifications

Industrial Control & Driving Subsystem Routing

• I/O Density Scaling and Process Terminal Interconnection The 44-pin structural wiring matrix maps the entire multi-rail LocalBus architecture across separate physical carrier steps. This enables field engineers to scale high-density automation arrays by placing multiple I/O sub-racks across separate horizontal rows inside the marshalling cabinet, preserving orderly processing terminal distribution without choking spatial envelope bounds.
• Backplane Bus Communication Velocity Licences and Firmware Flash Compatibility This interconnect assembly functions as a passive physical layer extension running directly underlying active communication nodes. Because it utilizes solid-state parallel copper tracks rather than active processing chips, it passes data frames at full native backplane bus communication velocities with zero software execution delay, operating completely independent of firmware flash revisions or software license limits.

Frequently Asked Questions

Q: Under what conditions should the 1.2-meter extender cable be deployed in a DeltaV layout?

A: The 1.2-meter version is utilized when the internal LocalBus must span across separate structural framing rows or skip wide gaps between horizontal carrier segments. The physical length limits are restricted to prevent signal degradation and clock skew across the passive high-speed parallel bus lines.

Q: Does the KJ4002X1-BF2 cable interface handle field-side instrumentation power distribution?

A: No. The 44-pin internal trace layout is engineered strictly to bridge low-voltage logic control power (12 VDC) and parallel backplane address/data signals between the carrier segments. High-current bussed field power for field device loops must be wired separately to each individual carrier terminal distribution network.
