Allen-Bradley 2094-BC04-M03-S Integrated Axis Module with Safe Torque-Off

Product Description

The Allen-Bradley 2094-BC04-M03-S operates as a foundational component of the Kinetix 6000 multi-axis servo drive system, serving as an Integrated Axis Module (IAM). This 100% brand-new, original unit integrates both power conversion and inversion logic into a single chassis-mounted module. By consolidating these functions, the 2094-BC04-M03-S effectively powers and controls high-performance motors and actuators, delivering precise motion synchronization for complex industrial machinery and automated production lines.

Engineering Advantages

The 2094-BC04-M03-S provides several mechanical and electrical benefits that empower engineers to streamline motion control architectures:

• Consolidated Power Architecture: This module combines the functionalities of a converter and an inverter. Consequently, it reduces the overall footprint on the power rail and simplifies the DC-bus connection process for subsequent follower modules.
• Integrated Personnel Safety: The built-in Safe Torque-Off (STO) feature allows the drive to disable power to the motor without removing the main supply. Therefore, maintenance teams can perform tasks safely without cycling the entire system power, which significantly boosts operational productivity.
• Enhanced Overload Performance: Series B and C units support a 250% peak current rating. This increased overhead allows the drive to handle high-inertia starts and rapid acceleration cycles without triggering nuisance overcurrent trips.
• Simplified Rail Installation: Engineers must mount this module at the leftmost position on the Kinetix power rail. This standardized layout ensures efficient heat dissipation and clear cable management for feedback, motor power, and interface signal kits.

FAQs

• Does the 2094-BC04-M03-S include all necessary connectors?While the module includes the primary motor and brake power connectors, you must purchase separate connector kits for feedback and I/O interface signals to complete the installation.
• How do I configure the module for an ungrounded power system?The module arrives pre-configured for grounded operation. However, you can adjust the internal ground jumper settings to accommodate ungrounded or high-impedance power configurations common in certain industrial facilities.
• What is the primary difference between the Series A and Series C versions?The Series C version offers a much higher peak current capacity (250%) compared to the 150% rating of the Series A model. Additionally, later series often feature internal hardware refinements for better thermal stability.
• Can this module operate on single-phase power?The 2094-BC04-M03-S specifically requires a three-phase AC input or a compatible DC bus input. Always verify that your power supply meets the 324–528V AC three-phase specification to ensure stable operation.
