Emerson KJ4010X1-BF1 DeltaV Localbus Right Extender

Product Overview

The Emerson KJ4010X1-BF1 serves as the definitive Localbus Right Extender within the DeltaV distributed control system (DCS) physical architecture. This critical hardware bridge attaches directly to the far-right termination point of a horizontal system carrier row. It intercepts the internal data and power backplane lines—the Localbus—and redirects these essential communication tracks via an expansion cable down to an adjacent multi-row carrier assembly. By connecting separated hardware racks, the extender permits continuous, uncompromised system expansion without requiring additional expensive controller nodes. We guarantee this Localbus Right Extender arrives in 100% brand new, original factory-sealed condition.

Engineering Advantages

• High-Speed Bus Signal Regeneration Across Carrier Rows: The internal solid-state circuitry maintains high-frequency data signal integrity as the Localbus transitions away from the main rack. This technology stops packet dropped-frames and eliminates signal attenuation across multi-tier marshalling panels, ensuring crisp communications with distant I/O blocks.

• Ultra-Compact Footprint for High-Density Layouts: Physical dimensions of 16.8cm x 4.7cm x 4.4cm ensure the extender consumes negligible footprint space at the edge of the DIN rail. This compact design gives installation crews extra margin to route thick, structured field wiring bundles inside confined, shallow junction boxes.

• Low-Mass Design Resists Mechanical Rail Fatigue: Weighing just 0.15 kg, the module exerts minimal structural torque onto standard industrial mounting rails. This lightweight composition stops retention-clip bending and prevents accidental module disconnection during high-vibration heavy machinery plant operations.

• Direct Pin-to-Socket Backplane Interlocking: The module features a heavy-duty, factory-aligned male/female connector set that seats directly into the standard DeltaV carrier backplane. This direct-mating framework removes the need for delicate, unshielded jumper cables, completely blocking nearby high-voltage variable frequency drives (VFDs) from introducing electromagnetic noise.

FAQs

• Does this KJ4010X1-BF1 extender ship in its original Emerson factory packaging?

  Yes. We deliver this hardware module exclusively as a 100% brand new, factory-original component. It remains fully sealed inside its untouched, original Emerson anti-static protective wrap within the official manufacturer box, preserving all corporate asset stickers, tracking barcodes, and factory serial marks.

• Can I mount this extender on the left side of a DeltaV carrier row?

  No. Emerson engineered the KJ4010X1-BF1 specifically with right-hand physical keying configurations and pin layouts to terminate the right edge of a carrier row. If your structural expansion prints require a left-side bus entry on the subsequent lower row, you must pair this right extender with the corresponding left-side expansion counterpart module.

• Do I need to turn off system power before installing this Localbus extender?

  Yes. Unlike standard hot-swappable I/O cards, the Localbus extender routes the primary control network and power trunk lines for multiple downstream racks. Attaching or removing this extender on a live system can disrupt active backplane voltages, potentially causing a critical controller trip. Always isolate system power prior to mounting this hardware block.

• What type of cable connects this right extender to the next row?

  This extender utilizes a specialized, factory-manufactured Emerson Localbus expansion cable. The heavy-shielded cable secures directly onto the front connector face of the KJ4010X1-BF1, providing a highly isolated, low-impedance path that preserves digital data tracks between the individual carrier levels.
