Product Description

Overview

The KJ4001X1-CA1 from Emerson is a high-performance Power/Controller Carrier designed for DeltaV™ Series 2 distributed control systems. It serves as the backbone for nodes requiring high availability and reliability. Horizontally DIN-rail mounted, the carrier supports dual controllers and dual power supplies, enabling seamless redundancy and uninterrupted process control. It also acts as the central hub for power distribution and communication between the Control Network and downstream I/O modules.

Key Features

Redundancy Support

• Dual slots for controllers and power modules ensure continuous operation in the event of a hardware failure.

• Backplane design allows bumpless switchover between redundant controllers.

Modular Expansion

• Integrated plug-in interface enables easy connection of additional I/O carriers (e.g., KJ4001X1-BE1).

• System scalability without complex external wiring or downtime.

Integrated Communication Bus

• Redundant Ethernet ports for reliable Control Network connectivity.

• Local bus supplies 24V DC and high-speed data to all connected I/O modules.

Hardware Address Management

• Physical Carrier ID (Address Plug) ensures correct slot recognition.

• Replacement controllers automatically inherit slot configuration.

Industrial-Grade Reliability

• Operating temperature: -40°C to 70°C

• G3 conformal coating protects against humidity and corrosive substances

• Shock and vibration resistant, suitable for cabinets near heavy machinery
