Allen-Bradley 2094-BC04-M03-S Kinetix 6000 Integrated Axis Module

Product Overview

When high-performance motion control is critical for your automation line, the Allen-Bradley 2094-BC04-M03-S Kinetix 6000 Integrated Axis Module delivers reliable power and safety. This integrated axis module (IAM) combines a converter and inverter section in one unit, simplifying system design and reducing wiring. Designed for 400V class applications, it supports input voltages from 324-528 Volts rms 3 Phase (360-480 Volts nom) and provides a converter output of 28 kW with an inverter output current of 30 A. The module includes Safe Torque Off functionality for enhanced operator safety during maintenance or emergency stops.

Technical Specifications

The 2094-BC04-M03-S operates with an AC input frequency of 47-63 Hertz and draws a nominal AC input current of 44.0 Amperes. Its DC input voltage range (common bus follower) is 458-747 Volts. The internal shunt offers continuous power of 200 Watts and peak power of 22.5 Kilowatts with a resistance of 28.75 Ohms. Efficiency reaches 97%, minimizing energy loss. The module weighs 21.1 lbs (9.60 kg) and dissipates 94-255 Watts depending on load. Bandwidth specifications include Velocity Loop: 500 Hz and Current Loop: 1300 Hz, with a PWM frequency of 4 kHz. Operating temperature range is 32-122 F (0-50 C).

Industry Applications

This integrated axis module excels in packaging, material handling, and converting machinery where precise speed and torque control are essential. For example, in a high-speed labeling line, the 2094-BC04-M03-S provides the 30 A inverter output to drive servo motors with rapid acceleration and deceleration. Its Safe Torque Off feature allows operators to safely clear jams without disconnecting power, reducing downtime. Compared to separate converter and inverter solutions, this integrated design saves panel space and simplifies commissioning.

Installation & Setup Guidance

Mount the 2094-BC04-M03-S at the leftmost position on the power rail. Install the IPIM, Axis module, Shunt Module, and Slot filler module to its right. The module ships with wiring plug connector sets for motor power (MP) and motor/resistive brake power (BC). Ground jumper settings may be required for ungrounded or high impedance power configurations. By default, the module is set for grounded systems with P16 and P17 shorted; for ungrounded systems, short P18 and P19. Always verify input voltage matches your facility supply before powering up.

Maintenance & Reliability

Regular inspection of the internal shunt and cooling fans helps maintain the 97% efficiency rating. Check for dust accumulation on heat sinks and ensure ambient temperature stays within 32-122 F (0-50 C). The module's power dissipation varies with load—94 W at 20% load up to 255 W at full load—so adequate ventilation is critical. Periodically verify that Safe Torque Off wiring and connections are secure per the manufacturer's guidelines. With proper care, the 2094-BC04-M03-S delivers long service life in demanding industrial environments.

Compatibility & Integration

This IAM is part of the Kinetix 6000 drive system and integrates seamlessly with Allen-Bradley ControlLogix and CompactLogix controllers over SERCOS or analog interfaces. It supports 200V or 400V-class AC input power and is available in Series A, B, and C variants. Series A offers 150% peak current rating, while Series B and C provide 250% peak current for higher torque demands. The module can be used as a common bus follower with DC input voltage of 458-747 Volts, enabling shared DC bus configurations for energy savings.

Selection Guide & Purchasing Advice

Before ordering the 2094-BC04-M03-S, confirm your system voltage and current requirements. This module requires connector kits for input/output, safety, and feedback signals (catalog numbers 2090-K6CK-D44M, 2090-K6CK-D44S0, and 2090-K6CK-D15M) which are sold separately. Verify the series revision—Series B or C is recommended for applications needing higher peak current. For current pricing and availability, contact BluePLC Industrial.
