Product Description

Product Overview

The Emerson KJ3004X1-BA1 is a Local Bus Power Terminal designed for the DeltaV™ Distributed Control System (DCS). It acts as the primary interface between the DeltaV controller and I/O modules, injecting regulated 24 VDC into the local bus to power connected I/O cards and maintain robust communication across the system. This terminal supports plug-and-play installation and is suitable for both horizontal and vertical carrier configurations.

Key Features

• Provides stable 24 VDC local bus power for DeltaV I/O modules.

• Supports hot-swapping to minimize maintenance downtime.

• Compatible with M-series and S-series DeltaV carriers.

• Redundancy-ready to maintain system uptime in critical processes.

• Front-panel LED indicators for immediate bus power and fault status.

• Designed for harsh industrial conditions with G3 conformal coating.

• Supports H1 Fieldbus communication protocol for real-time device integration.

Performance Characteristics

Power Distribution and Stability

• Ensures even power delivery across the DeltaV local bus.

• Maintains signal integrity for reliable communication with I/O modules.

Redundancy and Reliability

• Works in redundant setups to provide seamless failover.

• Prevents process interruptions if the primary bus power fails.

Hot-Swappable Design

• Can be removed or replaced under power without shutting down the system.

• Reduces operational downtime during maintenance or upgrades.

Environmental Resilience

• Operating Temperature: -40°C to 70°C.

• Shock and Vibration: Engineered to withstand plant-floor conditions.

• G3 Coating: Protects internal electronics from moisture and corrosive gases.

Diagnostics and Monitoring

• Status LEDs show bus power health at a glance.

• Provides rapid visual feedback for troubleshooting and maintenance.
