KJ4001X1-NA1 12P3373X022 EMERSON DeltaV LocalBus Extender

EMERSON KJ4001X1-NA1 DeltaV M-series Cable Extender

The EMERSON KJ4001X1-NA1 12P3373X022, also cataloged as the KJ4001X1-NA1 Horizontal LocalBus Dual Right Cable Extender, operates as a dedicated hardware component for extending physical data paths within DeltaV Distributed Control System (DCS) architectures. Consequently, the unit routes internal LocalBus communication signals horizontally across separated I/O carrier zones to maintain structural bus continuity. Integrated terminal networks execute physical-layer bus extension across the dual right-hand ribbon cabling configuration, while an internal power distribution bus handles high-current DC power lines to sustain signal integrity across extended bus physical distances.

Hardware Specifications

Process Control & Channel-to-Channel Isolation

Specifically, the EMERSON KJ4001X1-NA1 12P3373X022 contains specific impedance-matching trace routing to maintain the integrity of embedded 4-20 mA HART loop protocol parameters passed along the main LocalBus segment. Furthermore, to counteract high-density bus noise across adjacent carrier nodes, the design incorporates channel-to-channel isolation methods via the passive partition of independent signal routing bands. Therefore, this layout prevents common-mode voltage offsets and parasitic ground loops from cross-coupling into adjacent analog lines, thereby stabilizing signal transmission paths between distinct M-series I/O groups.

Frequently Asked Questions

Q: Does the EMERSON KJ4001X1-NA1 12P3373X022 cable extender limit the hot-swap capability of active I/O modules on the connected carrier?

A: No, the extender maintains continuous backplane bus connection integrity; as a result, operators can hot-swap individual functional I/O cards on the local carrier rows without disrupting bus termination stability.

Q: What is the primary purpose of the rated 12 VDC at 8 A electrical specification on the EMERSON KJ4001X1-NA1 12P3373X022?

A: In particular, this parameter specifies the maximum allowable pass-through current capacity handled by the internal heavy-gauge power rails to supply downstream I/O modules across the extended LocalBus segment.

Field Installation Guidelines

First, mount the EMERSON KJ4001X1-NA1 12P3373X022 extender module directly onto the designated right-hand side of the horizontal M-series carrier block to lock the interface pins into the LocalBus backplane. Subsequently, fasten all dual extension ribbon cables securely into their respective receptacle blocks using the built-in mechanical retention clips to counter high-frequency vibration loosening. In addition, route all parallel backplane extension cables completely away from high-voltage AC mains line conduits by a minimal boundary of 100 mm to block inductive noise coupling. Finally, ensure the system single-point safety ground connects firmly to the primary DIN-rail support framework prior to powering up the 12 VDC rail.
