Product Overview

The Allen-Bradley 2094-BC04-M03-S is a high-performance Integrated Axis Module (IAM) belonging to the Kinetix® 6000 multi-axis servo drive family. This dual-purpose module serves as the foundational unit for a motion control system, housing both the converter (rectifier) and the initial inverter (drive) logic in a single compact chassis. Engineered for 400V-class power systems, the 2094-BC04-M03-S provides the regulated DC bus voltage necessary to power subsequent Adjacent Axis Modules (AM) across the shared power rail.

By consolidating power conversion and axis control, the 2094-BC04-M03-S simplifies panel layout and reduces wiring complexity. This specific model features built-in "Safe Torque Off" (STO) functionality, meeting ISO 13849-1 standards to ensure that drive energy is removed from the motor during safety events without fully powering down the logic, allowing for faster machine restarts.

Motion Control and Energy Efficiency

The 2094-BC04-M03-S is optimized for precision multi-axis synchronization in demanding industrial environments.

• Integrated Conversion Logic: Functions as the primary power gate for the drive system, accepting three-phase AC input and converting it to a stable DC bus for all connected axes.

• Safety Compliance: Features integrated "Safe Torque Off" circuitry, which prevents the drive from generating torque-producing power during an E-stop or safety gate breach.

• Peak Current Flexibility: Series B and C iterations of this module offer an enhanced peak current rating of 250%, providing the overhead required for high-acceleration "peak-and-hold" motion profiles.

• Intelligent Power Dissipation: Managed thermal performance with a dissipation range of 94W at 20% load up to 255W at full 100% capacity.

• Flexible Grounding: Includes a pre-installed ground jumper suitable for grounded wye power systems, which can be reconfigured for ungrounded or high-impedance configurations.

Industrial Utility and Installation Requirements

As the "Master" module of the Kinetix 6000 drive system, the 2094-BC04-M03-S is critical for the following applications:

• Packaging Machinery: Synchronizing multiple servos for high-speed pick-and-place and wrapping.

• Material Handling: Managing complex sortation systems and automated storage/retrieval (AS/RS).

• Automotive Assembly: Providing precise torque control for robotic end-effectors and transport lines.

Note for Installation: The 2094-BC04-M03-S must always be mounted in the leftmost position on the 2094 Power Rail. It features dedicated motor and brake power connectors; however, feedback (encoder) and digital I/O interface connections require separate 2094-series connector kits for full integration.
