Product Overview
Allen-Bradley 25B-B2P5N104, 25B-B8P0N104 and 25B-B5P0N104 are PowerFlex 525 adjustable-frequency AC drives that convert 200…240 V three-phase input into controlled three-phase motor output. Within a motor-control system, 25B-B2P5N104, 25B-B8P0N104 and 25B-B5P0N104 regulate motor speed and torque from local, terminal or EtherNet/IP commands.
Incoming power reaches 25B-B2P5N104, 25B-B8P0N104 and 25B-B5P0N104 through R/L1, S/L2 and T/L3, passes through the drive power stage, and leaves through U/T1, V/T2 and W/T3. The three Frame A drives share that power path but provide different outputs: 2.5 A, 8.0 A and 5.0 A for 0.5 HP, 2 HP and 1 HP motors.
For control, 25B-B2P5N104, 25B-B8P0N104 and 25B-B5P0N104 combine an integral keypad with digital and analog terminals, relay contacts and embedded EtherNet/IP. Command data can enter through the control terminals or network adapter, while operating state and drive data return through the configured outputs and EtherNet/IP connection.

Product Functions
25B-B2P5N104, 25B-B8P0N104 and 25B-B5P0N104 coordinate command selection, motor-frequency control and status output inside one PowerFlex 525 unit.
Motor output control
The drive power stage converts the fixed-frequency AC supply into variable-frequency output at U/T1, V/T2 and W/T3.
Status return
Relay, analog and network data paths can report configured operating conditions to the connected control system.
Communication and Connectivity
The embedded EtherNet/IP adapter in 25B-B2P5N104, 25B-B8P0N104 and 25B-B5P0N104 links drive commands and operating data to an Ethernet control network.
Address assignment
BOOTP or the embedded-adapter parameters provide the IP address, subnet mask and gateway values.
Cyclic data path
The controller sends command data to the adapter and receives drive status through the established EtherNet/IP connection.
Shield reference
Terminal C1 is tied to the RJ45 shield and connects to clean ground for the specified star-topology grounding arrangement.
Frequently Asked Questions
How do the output ratings differ between 25B-B2P5N104 / 25B-B8P0N104 / 25B-B5P0N104?
The three drives provide 2.5 A, 8.0 A and 5.0 A outputs respectively. Compare the complete catalog number with the motor-current requirement before selecting the rating.
Do 25B-B2P5N104 / 25B-B8P0N104 / 25B-B5P0N104 use the same physical frame?
Yes. Every catalog number in this group is assigned to Frame A even though the output ratings differ.
How is the network address established for 25B-B2P5N104 / 25B-B8P0N104 / 25B-B5P0N104?
Use BOOTP or the embedded-adapter parameters to assign the EtherNet/IP address. A manual change becomes active after reset or a power cycle.
What is the brake-hardware arrangement on 25B-B2P5N104 / 25B-B8P0N104 / 25B-B5P0N104?
Each listed drive includes a brake IGBT. The external braking circuit, when used, must follow the terminal and resistor limits for the selected drive.
What does N104 mean for 25B-B2P5N104 / 25B-B8P0N104 / 25B-B5P0N104?
N104 identifies an IP20 NEMA / Open Type configuration without an integral EMC filter. It must be read as part of the complete catalog number.
Why can an open stop path prevent 25B-B2P5N104 / 25B-B8P0N104 / 25B-B5P0N104 from running?
Control terminal 01 is always a stop input. Its circuit and the configured stopping method must both permit operation before a start command can take effect.
