Product Overview
Allen-Bradley 25A-D1P4N104 and 25A-D2P3N104 are Frame A PowerFlex 523 AC drives for 380…480 V three-phase supplies. 25A-D1P4N104 controls a 0.4 kW (0.5 HP) motor at 1.4 A, and 25A-D2P3N104 controls a 0.75 kW (1 HP) motor at 2.3 A.
Control signals enter 25A-D1P4N104 and 25A-D2P3N104 through the digital-input group, the selectable 0…10 V or 4…20 mA analog input, or the RS-485 DSI port. The drive processes the selected start, stop and speed references, then returns configured state through its relay contacts and analog output.
Power for 25A-D1P4N104 and 25A-D2P3N104 enters at R/L1, S/L2 and T/L3 and leaves for the motor at U/T1, V/T2 and W/T3. Both catalog numbers use vertical IP20/Open Type mounting; the D1P4 rating cannot use either horizontal mounting method.

Product Functions
25A-D1P4N104 and 25A-D2P3N104 combine motor-output control with hardwired command inputs and configurable status outputs.
Speed reference input
The analog input accepts a voltage or current reference when the selector and parameters match the connected signal.
Output signaling
Relay contacts and the analog output return configured drive conditions to external control hardware.
Configuration and Programming
Operating behavior in 25A-D1P4N104 and 25A-D2P3N104 is set by matching parameters to the selected terminal or DSI command path.
Reference source
A parameter selects whether speed comes from the keypad, analog input, preset value or serial communication.
Digital assignments
Programmable input parameters connect each wired terminal to its required run, direction or auxiliary function.
Serial settings
The RS-485 DSI node address and communication settings identify the drive on the connected serial network.
Frequently Asked Questions
Why is control terminal 01 important on 25A-D1P4N104 / 25A-D2P3N104?
Terminal 01 is always the stop input on the PowerFlex 523 control block. The configured stop method determines the response when that path opens.
Which analog reference forms can 25A-D1P4N104 / 25A-D2P3N104 accept?
The analog input can be arranged for a 0…10 V or 4…20 mA reference. Wiring, selector position and parameter settings must agree.
Where is serial communication connected on 25A-D1P4N104 / 25A-D2P3N104?
The embedded RS-485 (DSI) interface is available at the RJ45 connector. Network address and cable routing are configured as part of the serial link.
What mounting orientation is used for 25A-D1P4N104 / 25A-D2P3N104?
The normal arrangement is vertical mounting. Keep the cooling openings clear and apply the required surrounding space.
Why do 25A-D1P4N104 / 25A-D2P3N104 need cabinet clearance despite their small rating?
Frame A still depends on unrestricted cooling air and separation from heat sources. Small motor power does not remove the thermal layout limits.
Do 25A-D1P4N104 / 25A-D2P3N104 contain an integral EMC filter?
No. Both complete N104 catalog numbers identify configurations without an integral EMC filter.
