Emerson KJ4002X1-BF3 DeltaV Horizontal Carrier Extender
The Emerson KJ4002X1-BF3, also cataloged as the KJ4002X1-BF3 Bottom Extender Cable Assembly, operates as a dedicated hardware component for LocalBus connection extension within DeltaV Distributed Control Systems platforms. The hardware establishes electrical continuity between adjacent horizontal carriers to support structural layout modifications without signal degradation.

Process Control & DCS Instrumentation Properties
The Emerson KJ4002X1-BF3 utilizes specific 44-pin male-to-female interfaces to maintain the continuous execution of the local backplane bus communication velocity protocol. Channel-to-channel isolation metrics are dictated by the underlying DeltaV carrier hardware architecture, while the physical cable media ensures standard 4-20 mA HART loop protocol variables and digital control signals pass through the LocalBus interface without impedance anomalies. The gold-plated contact structure prevents oxidation at the junction points, mitigating the risk of high-resistance faults that disrupt critical logic execution.
Frequently Asked Questions
Q: What is the mechanical limit regarding bending and routing for the 0.8-meter assembly?
A: The physical length is fixed at 0.8 meters. Interconnecting horizontal carriers must be positioned within an envelope that prevents structural tension or tight bends on the 44-pin terminations to avoid internal wire fatigue.
Q: Can the KJ4002X1-BF3 connection be severed or connected while the DeltaV LocalBus is powered?
A: No, hot-swapping or disconnecting the LocalBus extender cable during active system operation disrupts the active backplane data loop. This action will cause immediate downstream I/O dropouts and CPU fault states.
Field Installation Guidelines
- Connector Alignment: Align the 44-pin male and female terminations straight before insertion. Uneven insertion forces can bend the gold-plated pins, permanently damaging the LocalBus interface.
- Routing Constraints: Route the extender cable away from high-voltage motor leads, variable frequency drives, and heavy AC power lines to suppress electromagnetic interference on the system backplane logic.
- Strain Relief: Fasten the cable assembly along the internal cabinet structure using industrial tie-wraps to guarantee that the weight of the cable does not exert continuous mechanical pull on the carrier sockets.
