EMERSON KJ2003X1-BA2 Controller

Product Dimensions：

The Emerson KJ2003X1-BA2 is a high-performance Local Bus Extender (Right Hand) module designed for the DeltaV™ Distributed Control System (DCS). It is a critical component for expanding the physical reach of the DeltaV controller’s I/O bus.

1. Product Detailed Description

The KJ2003X1-BA2 acts as a bridge for the DeltaV local bus. In a standard DeltaV setup, the I/O carriers are attached directly to the controller. However, when the number of I/O modules exceeds the space of a single row or cabinet, this extender module is used.

• Function: It extends the communication and power bus from one power supply/controller carrier to the next set of I/O carriers.

• Design: It is specifically the Right Hand (RH) version, typically used at the end of a row to “send” the bus signal via a cable to the next row’s “Left Hand” extender.

2. Technical Parameters

3. Key Product Advantages

• Scalability: Allows the DeltaV system to grow by adding more I/O modules across multiple rows without needing additional controllers.

• Hot-Swappable: Like most DeltaV components, it can be replaced while the system is powered (though bus communication to downstream modules will be interrupted).

• Industrial Durability: Built to withstand harsh environments with wide temperature ranges and G3 conformal coating options for corrosion resistance.

• Plug-and-Play: Integrated seamlessly into the DeltaV Explorer software for easy diagnostics and configuration.

4. Important Considerations & Precautions

• Cable Length Limits: Ensure that the total length of the extension cables does not exceed the maximum bus length specified by Emerson (typically 10 meters or 33 feet total for the entire bus).

• Orientation Matters: The BA2 is a Right-Hand extender. It must be paired correctly with a Left-Hand extender (KJ2003X1-BB1) on the receiving row.

• Power Budget: While the extender carries the data bus, you must ensure the downstream carriers have their own power supplies if the voltage drop across the extension is too high.

• ESD Protection: Always use a grounding wrist strap when handling the module to prevent Electrostatic Discharge damage to the internal circuitry.

5. Product Applications

The KJ2003X1-BA2 is found in large-scale industrial automation environments where high I/O density is required, such as:

• Oil & Gas: Refineries and offshore platforms.

• Chemical Plants: For managing complex batch processing.

• Pharmaceuticals: Maintaining precise control over environmental and chemical variables.

• Power Generation: Managing plant-wide logic and monitoring.
