The Allen-Bradley 25A-A4P8N104 is part of the PowerFlex 523 Adjustable Frequency AC Drives. This drive is mainly used for implementing standard motor control and complex functionalities such as analog control of speed and torque of an industrial AC motor. Additionally, the 25A-A4P8N104 can be used to implement energy-saving measures by controlling the starting and stopping characteristics of the connected motor. The 25A-A4P8N104 is capable of being configured with a variety of control methods such as Volts per Hertz (V/Hz), Sensorless Vector Control (SVC), and SVC with economizer. It is also provided with a sufficient number of embedded I/O channels such as Five (5) digital inputs, One (1) analog input One (1) relay output, and One (1) analog output with firmware revision 3 or Series B drive or higher. These I/O channels enable remote and flexible operation of the drive-by hardwiring external signaling and indicating devices such as pushbuttons, pilot lamps, and controllers. In addition, the drive may be locally controlled and monitored through the built-in standard interface module. The 25A-A4P8N104 is also provided with an RS485 communication interface that supports daisy-chain topology, allowing multiple drives and MODBUS RTU-capable devices to be connected to the network. This port may also be used for direct integration to a Programmable Logic Controller (PLC), Programmable Automation Controller (PAC), Human Machine Interface (HMI), and Supervisory Control and Data Acquisition system (SCADA) for software-based configuration, monitoring, control, maintenance and troubleshooting and implement a dynamic method of operating the drive. Optional communication cards may also be installed on the drive to further enhance the communication capability of the 25A-A4P8N104.

The Allen-Bradley 25A-A4P8N104 is a PowerFlex 523 series 200-240V AC single-phase drive with an A-frame size and no filtering. It comes with an output current of 4.8 A and a line frequency of 50-60 Hz. This drive has a wattage of 0.75 kW and 1 HP in both normal duty and heavy-duty applications. It also has an input rating of 2.8 kVA and maximum amps of 10.7 A. The enclosure ratings of this drive are the open type and the NEMA Type IP20 enclosure. It has 5 digital inputs, 1 relay input, and 1 analog input installed. The 25A-A4P8N104 also comes with a dual-port Ethernet/IP option card and an embedded Ethernet/IP port, but you can also install an optional DeviceNet or PROFIBUS DP communication card to it. It also features an online EDS file creation application and integral RS-485/DSI communications. Sensorless vector control and volts per hertz control are present on this drive. It also comes with a display, status indicators, and a keypad input.
