Emerson KJ4010X1-BG1 12P0830X062

The Emerson KJ4010X1-BG1 12P0830X062 supplied by Yueyang Tongtu from China is a LocalBus Right Extender module used in the Emerson DeltaV distributed control system. It sits between I/O carriers and passes the LocalBus communication from the current carrier to the next carrier on the right, enabling daisy-chaining of additional I/O sub-racks.


The Emerson KJ4010X1-BG1 12P0830X062 supplied by Yueyang Tongtu belongs to the DeltaV M-series I/O subsystem and functions as a carrier module. It does not perform signal conversion or logic processing; its role is to maintain electrical and mechanical connection of the LocalBus, passing both data and power from the left carrier to the right carrier.


This module is typically needed when an existing DeltaV rack has run out of I/O slots and additional carriers are required to accommodate more I/O modules. By installing the Emerson KJ4010X1-BG1 12P0830X062 in the appropriate slot, the LocalBus is extended to the new sub‑rack, allowing the additional I/O modules to be managed by the same controller.

Product Features

Capacity expansion without controller replacement

When using this module to add I/O capacity, the DeltaV controller remains unchanged, and the system configuration does not require a full download.

Hazardous area certification

The module carries ATEX Zone 2, IECEx, FM Class I Division 2, CSA, and UKEX certifications. It can be installed directly in industrial sites with flammable gases or dust, such as refineries, chemical plants, and natural gas processing facilities.

Wide temperature range

The operating temperature range is –40°C to +70°C, making it suitable for outdoor cabinets, non-air-conditioned rooms, and extreme climate conditions.

Tool-free installation

The module uses a snap-in design. It can be inserted into the backplane guide slots until the latch engages, requiring no special tools.

Mechanical robustness

The module meets ISA-S71.04-1985 Class G3 for airborne contaminant resistance and withstands 10g shock (half-sine, 11ms) and 1mm peak-to-peak vibration.

Installation Instructions

Before installing or removing the Emerson KJ4010X1-BG1 12P0830X062, the DeltaV rack power must be switched off. The module must not be inserted or withdrawn while the system is energised.

Installation steps:

1. Ensure the system is powered off and the area is safe.

2. Align the module with the backplane guide slots and push it in horizontally.

3. Insert until the latch mechanism engages, and verify that the module is flush with adjacent carriers and securely seated.

After installation, no calibration or parameter configuration is required, as the module contains no adjustable components or user-serviceable parts.

Two important points to note:

1. Removing any carrier module while the system is powered will interrupt LocalBus continuity, causing all downstream carriers to lose communication with the controller.

2. For LocalBus cables crossing between enclosures in hazardous areas, conduit protection per NEC or IEC requirements must be applied.

Selection Guide

Before ordering the Emerson KJ4010X1-BG1 12P0830X062, the following items should be verified:

Expansion direction

This model is a right extender. If the rack layout requires leftward bus extension, a different model is needed. Check the rack arrangement drawing before placing an order.

Total daisy-chain length

Add the widths of all existing and proposed carriers to confirm that the total length does not exceed 6.5 metres. If the total exceeds this limit, consider partitioning the system or adding another controller rather than continuing to chain extenders.

Hazardous area classification

Confirm that the site’s hazardous area classification matches the module’s certifications. This module is suitable for Zone 2 and Class I Division 2. It is not approved for Zone 0 or Zone 1.

Power budget

The LocalBus provides 12.6 VDC at a maximum of 8A. Each additional carrier and its I/O modules will add to the power consumption. Calculate the current load before expansion to ensure sufficient power reserve.

Product availability

This model is discontinued. For new projects, assess whether surplus stock will be sufficient for long-term maintenance needs. For existing system expansions or spare parts replenishment, stock channels are generally adequate.

FAQ

Q: Is this model still in production?

A: No. Emerson discontinued it on December 31, 2018. Current supply comes from factory surplus or tested used stock.

Q: What is the difference between a left extender and a right extender?

A: The right extender (KJ4010X1-BG1) passes the LocalBus from the current carrier to the next carrier on the right. The left extender passes it to the left. They have different physical connector orientations and cannot be used interchangeably. Confirm the direction before ordering.

Q: Does the module require calibration or configuration after installation?

A: No. It is a passive hardware extender with no adjustable components, so no calibration or software setup is needed.

Q: Can the module be inserted or removed while the system is running?

A: No. The system must be fully powered off before any insertion or removal. Hot-swapping will interrupt the LocalBus and may cause communication failures.

Q: What happens if the daisy‑chain length exceeds 6.5 metres?

A: Beyond 6.5 metres, signal integrity and timing cannot be guaranteed, which may lead to communication errors or module drop‑outs. This limit is due to the electrical drive capability of the bus and cannot be overcome by adding more extenders.
