Allen-Bradley 22B-D1P4N104 Variable Frequency Drive

Allen-Bradley PowerFlex 40 series 22B-D1P4N104 is a compact 0.4 kW (0.5 HP) AC drive that accepts 480V three‑phase input and delivers up to 1.4 A to the motor. It comes in an IP20, NEMA/UL Type Open enclosure suitable for panel mounting in industrial control cabinets and includes RS-485 communications for integration with PLCs or HMIs. The drive provides three fixed inputs for START/STOP/REV and four fully programmable discrete inputs, plus two programmable discrete outputs and one normally‑open/normally‑closed dry contact. On the analog side it offers two 0–10 V or 4–20 mA inputs, one bipolar ±100 V analog input, and a 0–10 V/4–20 mA analog output for feedback and control signals. This 22B-D1P4N104 variant is specified without an internal EMI filter. As part of the PowerFlex 40 family, it targets small to mid-range motor control applications, enabling precise speed and torque management for 3‑phase motors in industrial settings. Typical uses in 480V three‑phase environments include process or machine automation tasks where compact, flexible speed control is required, such as fans, pumps, or light conveyors, with a straightforward control interface and standard safety and UL/NEMA open‑type compatibility.
