Product Overview
The Allen-Bradley 22B-B5P0H204 PowerFlex 40 AC Drive delivers reliable variable-speed motor control in a compact, IP20-rated enclosure. This industrial automation module from the PowerFlex 40 family operates on 240V AC, 3-phase input at 50–60 Hz and provides a 5-amp output current. Designed for straightforward programming and flexible integration, the 22B-B5P0H204 supports RS-485 communication and includes advanced diagnostic features to minimize downtime.
With a 1 HP rating and 0.75 kW output, this drive suits fractional-horsepower applications requiring precise speed regulation. Its open network architecture supports EtherNet/IP, DeviceNet, and ControlNet via Common Industrial Protocols (CIP), making it easy to integrate into existing automation systems.

Industry Applications
The 22B-B5P0H204 excels in fan, pump, and conveyor applications where energy savings and precise speed control matter. For example, in a packaging line, this drive maintains consistent belt speed despite load variations, reducing product waste. In HVAC systems, it modulates fan speed based on demand, cutting electricity costs.
Installation & Setup Guidance
Before applying power, tighten all terminal screws to the recommended torque—shipping vibration can loosen them. Mount the drive on a flat, non-flammable surface with adequate clearance for airflow. Follow the wiring diagram in the user manual, ensuring correct phase and ground connections. The keypad allows quick setup of motor parameters, acceleration, and deceleration ramps.
Maintenance & Reliability
Regularly inspect the drive for dust accumulation on the heatsink and internal components. Clean with dry compressed air at low pressure. Check terminal connections for tightness every six months. Operating within the specified ambient temperature range (32–140 °F) maximizes reliability and extends service life.
Compatibility & Integration
The 22B-B5P0H204 communicates via RS-485 and supports EtherNet/IP, DeviceNet, and ControlNet networks through optional communication modules. This makes it compatible with Allen-Bradley PLCs (e.g., ControlLogix, CompactLogix) and third-party systems using CIP. Use the drive's built-in I/O for simple start/stop and speed reference control.
Selection Guide & Purchasing Advice
When ordering, verify your input voltage and phase match the drive's rating (200–240V AC, 3-phase). Confirm the motor's full-load current does not exceed the drive's output current rating. For CE-marked installations, note that this unit does not include a built-in CE filter; you may need an external filter. PLC Source PRO offers genuine Allen-Bradley parts with fast worldwide shipping.
