Product Overview – 25B‑E1P7N104 PowerFlex 525 Drive
When older AC drives fail to deliver the connectivity and energy efficiency required by modern networked machinery, the Allen‑Bradley 25B‑E1P7N104 PowerFlex 525 adjustable frequency AC drive provides a direct upgrade path. As part of the proven PowerFlex 525 series, this compact A‑frame drive combines built‑in Ethernet/IP, six digital inputs, and multiple control methods — all in an IP20 NEMA/open type enclosure. The 25B‑E1P7N104 is engineered to replace legacy drives while reducing panel space and integration effort.

Real‑World Applications
In conveyor systems, packaging machines, and material handling lines, the 25B‑E1P7N104 delivers precise speed and torque control. Its Ethernet/IP communication enables seamless integration into Logix environments, making it an ideal replacement for older non‑networked drives. For pump and fan applications, the PID controller maintains setpoints without an external controller. The 25B‑E1P7N104’s built‑in Safe Torque‑off and integrated safety options reduce wiring and increase machine availability.
Installation & Setup Guide
Mount the 25B‑E1P7N104 vertically in a clean, dry area with unrestricted airflow. The IP20 NEMA/open type enclosure requires no additional filtration. Connect 525‑600 VAC three‑phase power to the input terminals, and motor leads to the output (0‑575 VAC, 1.7 A). Use the standard interface module to configure parameters via the built‑in Ethernet/IP port or the optional dual‑port card. The DSI port allows up to five drives on a single node. Ensure the control module fan kit is installed if horizontal mounting or higher ambient temperature operation is required.
Compatibility & Integration
The Allen‑Bradley 25B‑E1P7N104 communicates via Ethernet/IP and supports V/Hz, Sensorless Vector, Closed Loop Velocity Vector, and Permanent Magnet motor control. It integrates directly with Rockwell Logix controllers and can replace older PowerFlex 4 or 40 drives with minimal rewiring. The drive accepts two analog inputs and provides one analog output (requires Series B hardware) and two relay outputs for status feedback.
Selection Guide – Upgrading to the 25B‑E1P7N104
When upgrading from an older drive, verify that the motor nameplate rating does not exceed 1.0 HP (0.75 kW) and that the supply voltage matches 525‑600 VAC. The 25B‑E1P7N104 uses a standard interface module and built‑in IGBT braking, so no external brake resistor is required. For applications requiring an integrated EMC filter, consider an alternate PowerFlex 525 variant. PLC Source PRO stocks this drive and can advise on compatible accessories such as control module fan kits and DSI cabling.
