Product Introduction
The Emerson KJ4001X1-HB1 Localbus Right Extender is a critical component within the Emerson DeltaV™ Distributed Control System (DCS) architecture. It functions as a Localbus extender, used to connect multiple I/O carriers or expansion carriers in larger and more distributed control environments. As its name suggests, the “Right Extender” is installed on the right side of an I/O carrier and provides a secure and high-speed communication link between adjacent carriers or system backplanes.
This model ensures the continuity of the DeltaV Localbus, which is Emerson’s proprietary internal high-speed bus that supports module-to-module communication within the system. The KJ4001X1-HB1 plays a vital role in achieving the scalability and modularity for which DeltaV systems are known.
Compact, rugged, and easy to install, the KJ4001X1-HB1 provides high availability and performance for mission-critical process control environments.

Frequently Asked Questions (FAQ)
-
What is the function of the Emerson KJ4001X1-HB1?
It extends the DeltaV Localbus to the right, allowing the connection of additional I/O carriers or modules. -
Can this extender be used independently?
No, it must be used within the DeltaV control architecture, typically alongside I/O baseplates. -
Where should I install the KJ4001X1-HB1?
It is mounted on the right-hand side of a DeltaV I/O carrier or baseplate. -
Is the installation process tool-free?
Yes, it snaps into place without the need for tools, facilitating quick installation. -
Does this unit provide electrical isolation?
Yes, it is electrically insulated from field wiring to avoid interference. -
Is this compatible with legacy DeltaV systems?
It is compatible with DeltaV versions that support Localbus infrastructure, including most modern builds. -
Can it operate in outdoor environments?
Only when placed inside properly rated enclosures as it is not weatherproof by itself. -
What if I install it incorrectly?
Improper installation may cause a Localbus communication fault; always follow manufacturer guidance. -
Does it require firmware or software configuration?
No software configuration is required. It functions automatically upon correct hardware installation. -
Can I use more than one KJ4001X1-HB1 in a system?
Yes, multiple extenders can be used for each required I/O baseplate connection.
