The Allen-Bradley 2094-BC04-M03-S is a 28 kW Integrated Axis Module (IAM) for the Kinetix 6000 servo system. It combines a 30A inverter and converter with built-in Safe Torque-Off (STO) to provide high-performance, safety-rated motion control. This 400V-class module supports shared DC-bus architecture, enabling efficient power redistribution and up to 250% peak current for high-speed industrial automation.
The Allen-Bradley 2094-BC04-M03-S functions as the primary control and power distribution hub for the Kinetix 6000 multi-axis servo drive system. By consolidating a high-capacity DC-bus converter and a precision servo inverter into a single chassis, this Integrated Axis Module (IAM) effectively streamlines control cabinet architecture. It coordinates power delivery across the 2094 power rail, supplying the necessary DC voltage to downstream axis modules while maintaining high-fidelity synchronization for complex motion profiles.
Furthermore, this module prioritizes machine safety through its hardware-based Safe Torque-Off (STO) functionality. This feature actively prevents the drive from generating rotational force during safety events, which allows operators to perform maintenance without de-energizing the entire system. Consequently, facilities achieve higher throughput by significantly reducing restart delays. Beyond safety, the unit delivers a substantial 28 kW of power output, providing the electrical current required to drive high-inertia motors in demanding industrial environments.
In addition to its raw power, the 2094-BC04-M03-S offers exceptional adaptability for global power standards. It accepts a broad three-phase input range of 324V to 528V AC, making it suitable for 400V-class infrastructure worldwide. Moreover, Series B and C iterations of this hardware utilize enhanced power electronics to provide 250% peak current capacity. This capability enables the system to execute aggressive acceleration curves without tripping overcurrent protections. Finally, the shared-bus design facilitates intelligent energy recovery, as the module captures regenerative energy from braking axes and redistributes it to other modules on the rail, thereby lowering total power consumption.
