Product Overview

The Emerson KJ4001XI-NB1 1-Wide I/O Carrier Extender is engineered to support modular expansion of DeltaV DCS installations. It enables seamless extension of I/O carriers while maintaining stable power and signal integrity across distributed control architectures.

This extender is particularly useful in systems requiring additional I/O modules beyond the standard rack capacity. It supports dual DC/DC power conversion and delivers 12VDC at 8A via the local bus, ensuring consistent performance under demanding conditions.

Moreover, the KJ4001XI-NB1 is certified for use in hazardous environments, with robust shock resistance and a wide temperature tolerance. Therefore, it is ideal for mission-critical applications in industries such as oil & gas, chemical processing, and power generation.

Technical Specifications

Typical Applications / System Integration

The KJ4001XI-NB1 is commonly used in industrial automation systems requiring extended I/O capacity. For example:

• Oil & Gas: Supports remote I/O expansion on offshore platforms and in refineries.

• Chemical Processing: Enables modular control in hazardous zones where high I/O density is required.

• Power Generation: Facilitates scalability for turbine and boiler control systems.

• Water & Wastewater: Expands control capabilities across distributed pump stations and treatment units.

In addition, its rugged design and environmental resilience make it suitable for both indoor and outdoor installations.

System integrators benefit from simplified wiring, reduced cabinet space usage, and enhanced reliability in distributed control environments.
