EMERSON KJ4010X1-BG1 – DeltaV Bus Extender Module | DeltaV S-Series Platform
The EMERSON KJ4010X1-BG1 (Alternate P/N: 12P0830X062) is a dedicated bus extender module engineered for the Emerson DeltaV Distributed Control System (DCS) S-Series platform. Designed to extend the physical reach of the DeltaV controller bus, this module enables engineers to expand node capacity and optimize cabinet layout in large-scale process automation installations.
At Konmask.com, we supply this module to procurement engineers and MRO teams operating in refining, petrochemical, power generation, and continuous manufacturing environments where DeltaV system integrity is non-negotiable.

Proven Application Environments
- Oil & Gas Refining: Extending DeltaV controller nodes across large refinery DCS cabinets where physical distance between carriers exceeds standard bus reach.
- Petrochemical Plants: Multi-unit process control architectures requiring distributed I/O expansion without additional controllers.
- Power Generation: Boiler management and turbine control systems using DeltaV S-Series with extended node configurations.
- Pharmaceutical Manufacturing: FDA-regulated batch process systems where validated DeltaV configurations must be maintained during hardware replacement.
- Pulp & Paper / Mining: Continuous process environments with high I/O density requiring bus extension for remote carrier placement.

Engineering Advantages
- Seamless Bus Extension: Maintains full DeltaV bus integrity and communication speed across extended distances without signal degradation.
- Hot-Swap Compatible: Supports DeltaV carrier hot-swap procedures, minimizing process interruption during module replacement.
- No Additional Configuration: Recognized automatically by DeltaV system software — no manual addressing or firmware programming required.
- Compact Form Factor: Occupies a single slot on the DeltaV S-Series carrier, preserving valuable cabinet real estate.
- System Validated: Fully compatible with Emerson DeltaV v10.x through v14.x and later releases.
- Long Service Life: Industrial-grade components rated for continuous 24/7 operation in process control environments.
System Architecture & Signal Flow
The KJ4010X1-BG1 operates as a transparent bus bridge within the DeltaV S-Series architecture. It is installed in a designated slot on the primary carrier and connects via a dedicated bus cable to a secondary carrier, effectively extending the controller’s I/O bus. The DeltaV controller communicates with all I/O modules on both the primary and extended carriers as a single logical node. Signal flow is bidirectional: process data from field instruments travels upstream through I/O modules → carrier backplane → bus extender → controller, while control outputs follow the reverse path. The extender introduces no additional latency perceptible at the process control level.

Technical FAQ
Q: Is the KJ4010X1-BG1 compatible with DeltaV MD and MX controllers?
A: Yes. The bus extender is compatible with DeltaV MD, MX, and M-Series controllers operating on S-Series carriers. Confirm your carrier revision with Emerson documentation before installation.
Q: How many extenders can be daisy-chained in a single node?
A: Emerson specifies a maximum of one bus extender per controller node (primary + one extended carrier). Consult DeltaV hardware installation guide for your specific controller revision.
Q: Can this module be used as a direct replacement for a failed unit without DeltaV reconfiguration?
A: Yes. The KJ4010X1-BG1 is a plug-and-play replacement. No DeltaV database changes are required — the system recognizes the new module automatically upon insertion.
Q: Do you provide a test report or certificate of conformance?
A: Yes. A functional test report is available upon request. Certificate of Conformance (CoC) can be provided for qualified orders.
Q: What is the difference between KJ4010X1-BG1 and 12P0830X062?
A: These are the same physical module. KJ4010X1-BG1 is the Emerson engineering part number; 12P0830X062 is the manufacturing/revision-specific alternate part number printed on the module label.
