KJ4010X1-BG1 | Emerson DeltaV Localbus Right Extender Module

Product Overview

The Emerson KJ4010X1-BG1 acts as a heavy-duty Right Localbus Extender module within the DeltaV distributed control system (DCS) hardware ecosystem. This critical backplane infrastructure component installs directly onto the far-right edge of a horizontal I/O carrier row. It bridges the system data and internal power tracks—the Localbus—and carries these vital resources down to subsequent rows via an expansion cable. By maintaining high-current power continuity and signal integrity across segmented rack layers, this module enables extensive I/O capacity expansion without forcing engineers to buy extra control nodes. We guarantee this Right Localbus Extender arrives in 100% brand new, original factory-sealed condition.

Technical Specifications

Engineering Advantages

• High-Capacity 8 Amp Power Bus Delivery: The internal heavy-gauge power copper tracks handle up to 8 Amps of continuous current at 12.6 VDC. This high capacity allows the module to pass substantial operational power downstream, satisfying the energy demands of multiple multi-channel analog and digital I/O card layers on secondary carrier rows.

• Low-Impedance Backplane Signal Conditioning: Specialized solid-state circuitry maintains crisp digital data transmission speeds as the bus steps between separated DIN rail tiers. This low-impedance connection stops communication packet attenuation and eliminates signal reflection errors, preserving accurate data streams even in highly active automation clusters.

• Compact, Low-Mass Layout Resolves Cabinet Constraints: Weighing just 0.51 lbs, the slim mechanical enclosure minimizes weight and spatial volume on the edge of the mounting track. This small footprint gives engineering layout designers maximum clearance to dress field wire bundles properly inside shallow, packed junction boxes.

• Direct Mechanical Pin-Mating Defies Industrial Vibration: The precision-molded backplane interface plugs directly into the standard DeltaV carrier socket without requiring individual wire jumpers. This interlocking mechanical layout shields the connection point from intense machine vibration and nearby electromagnetic interference (EMI), keeping data pathways free of intermittent physical or electrical drops.

FAQs

• Does this KJ4010X1-BG1 extender ship in its original corporate packaging?

  Yes. We sell this industrial automation piece exclusively as a 100% brand new, factory-original component. The extender remains enclosed within its untouched Emerson anti-static protective wrapping inside the original corporate box, keeping all asset tags, tracking barcodes, and factory serial codes in pristine state.

• Can I use this module to extend the left side of a carrier row?

  No. Emerson keys the physical casing and internal pin layout of the KJ4010X1-BG1 exclusively for the far-right terminal slot of a DeltaV row assembly. Attempting to mount this on a left-hand termination slot will fail mechanically. You must purchase the dedicated left-side extender module to interface with the left-hand input slot of downstream rows.

• Do I need to isolate power before mounting or removing this module?

  Yes. Because the module routes the main 8 Amp, 12.6 VDC localbus power backbone and control network data to entire subsequent expansion rows, pulling or inserting this module while live can cause an electrical arc or disrupt the system backplane voltage. Always shut down power to the carrier sub-assembly before performing installation steps.

• What type of cable connects this module to the next rack layer?

  This right-hand extender links to downstream rows via a specialized, heavily-shielded Emerson Localbus expansion cable. The plug-in connection secures to the module front plate, forming a fully grounded envelope that stops radio frequency (RF) noise from corrupting system data packets.
