Emerson KJ4010X1-BG1 Right LocalBus Extender Module for DeltaV Systems

The KJ4010X1-BG1 Right LocalBus extender module expands the local bus of Emerson DeltaV control systems. This unit connects additional I/O carriers to the main controller over a short bus segment. Engineers specify it for flexible cabinet layouts where rack depth limits direct mounting.

Physical Dimensions and Weight

The KJ4010X1-BG1 measures 40 mm in width and 130 mm in depth. Its housing stands 105 mm tall, which fits standard DeltaV carrier positions in control cabinets. The module weighs approximately 0.25 kg, so carrier loading stays balanced during system builds.

Interface and Connectivity

This module links to the controller through 1 LocalBus connector on the left edge. The KJ4010X1-BG1 provides 1 LocalBus outlet on the right edge for the next carrier segment. Consequently, technicians can chain carriers without long cable runs. Four LEDs report power, bus activity, and fault status during operation.

Component Count and Build

Each KJ4010X1-BG1 contains 1 bus buffer circuit, 1 termination network, and 1 diagnostic controller. The assembly includes 1 mounting bracket and 2 screws. Furthermore, 1 jumper block sets the bus termination state for the chain position.

Energy Storage and Power Parameters

The module draws 5 VDC logic power from the carrier backplane. A 0.022 F capacitor stabilizes the bus driver rail during burst traffic. Therefore, the KJ4010X1-BG1 keeps signal timing consistent through brief supply dips. The design stores no long-term energy and needs no backup battery.

Key Technical Parameters

Integration Notes

The KJ4010X1-BG1 mounts in standard DeltaV carrier positions without adapters. Technicians set the termination jumper according to the chain position before startup. Additionally, the bus buffer keeps signal integrity high across extended carrier runs.
