Overview
The Allen-Bradley 22A-D1P4N104 is a PowerFlex 4 adjustable frequency AC drive designed for compact, cost-effective motor speed control. Rated at 0.4 kW (0.5 HP), it operates on 480VAC, 3-phase input and delivers straightforward control solutions for small industrial applications including fans, pumps, conveyors, and process machinery. This drive is one of the smallest and most economical members of the PowerFlex family, making it ideal for space-constrained OEM and end-user installations.
Key Features

Typical Applications
The 22A-D1P4N104 is well-suited for single-motor, small-scale applications requiring straightforward speed or torque modulation:
- HVAC fan and blower speed control
- Centrifugal pump flow regulation
- Small conveyor systems and material handling
- Mixer and agitator motor control
- Machine-tool spindle speed adjustment
- Standalone process control with integrated PID loop
Compatibility & Replacements
The 22A-D1P4N104 integrates seamlessly into Rockwell Automation control ecosystems. It supports programming and configuration via Logix-based controllers (CompactLogix, ControlLogix) and integrates with Studio 5000 Logix Designer or RSLogix 5000. Communication via Logix runtime using standard PowerFlex messaging simplifies integration into networked systems.
End-of-Life Notice: The 22A-D1P4N104 was discontinued as of June 30, 2025. For new installations, Rockwell Automation recommends the 25A-D1P4N104 as the engineering replacement. This used unit is an excellent option for replacement or spare-inventory applications where immediate availability is critical.
Common Variants: The PowerFlex 4 series includes multiple frame sizes and power ratings (0.25–15 HP). Related part numbers include the 22A-D0P5N104 (0.25 HP), 22A-D2P2N104 (1.5 HP), and 22A-D4P0N104 (2 HP).
