Product Overview
The Emerson KJ4002X1-BA1 Vertical Left-Side 8-Wide I/O Carrier is a robust I/O Carrier Assembly designed for the Emerson DeltaV™ Distributed Control System (DCS). It provides a secure mechanical and electrical platform for mounting and interconnecting up to eight DeltaV I/O modules in a vertical left-side configuration, enabling scalable, organized, and reliable process automation installations.
The KJ4002X1-BA1 serves as the structural backbone of the DeltaV I/O subsystem by supporting the installation of I/O cards while distributing power and maintaining communication through the local bus infrastructure. Its modular design allows engineers to expand automation systems efficiently while simplifying cabinet layout, maintenance, and future upgrades.
Designed for continuous industrial operation, the carrier features heavy-duty industrial construction capable of withstanding vibration, temperature fluctuations, and harsh control cabinet environments. The vertical mounting arrangement optimizes cabinet space utilization while improving cable organization and service accessibility.
With compact dimensions of 255 × 25 × 102 mm and an approximate weight of 0.32 kg, the KJ4002X1-BA1 provides an ideal mounting solution for high-density DeltaV control systems.
Typical applications include oil and gas production, petrochemical plants, chemical processing facilities, power generation, pharmaceutical manufacturing, food and beverage production, mining operations, pulp and paper mills, and water and wastewater treatment systems.
