The 8520-AA12 is a servo amplifier; its main function is to provide the appropriate power supply to a compatible servomotor. The 8520-AA12 servo amplifier is manufactured by Allen-Bradley and belongs to the 9/series. It is fully compatible with the 9/series drives and processors. The 8520-AA12  can also be paired with a wide range of servo motors, in addition to the 9/series units. The installation of this unit is simple, but it requires that the amplifier is placed in a different location than the drive, at a distance that doesn’t affect the signals due to the electrical disturbance that is produced while it is operating. The Allen-Bradley 8520-AA12 servo amplifier is multi-axis, meaning that has three axis or servos that allows the unit to operate with more efficiency than those single axis servo amplifiers. In addition, this unit operates at 12 Amps.

The operative level of this Allen-Bradley 8520-AA12 servo amplifier is designated by the servo motor to which it is applied. Once the servo motor has sent feedback and this feedback has been caught by the servo module, the servo module sends this signal to the servo amplifier. This way, the servo amplifier is able to send the required amount of power to the servo motor. The Allen-Bradley 8520-AA12 servo amplifier is manufactured with a shaft seal made of Teflon, making it highly resistant and capable of withstanding high pressures, temperatures, and dry running and aggressive environments. The applications of this Allen-Bradley 8520-AA12 servo amplifier are available whenever there is a need to preserve and boost the effectiveness of a servo motor. This amplifier’s function types are used in many currently relevant applications.
