8520-ENC4/B
Specs & Technical Data
Specifications: Allen-Bradley 8520-ENC4 Digital Servo Module, Number of Axes: 4; Input Power Range for Encoders:+5V (+10%, -1%), +15V (±7%); Maximum Input Frequency of Encoder Feedback: 2 MHz; Desired Voltage Range of Encoder Battery Backup: 3.5-4.5V; DAC Output Voltage Range: ±10V; DAC Resolution: 2.44mV; DAC Sampling Frequency: 1000 Hz; DAC Output Current, Max: 5 mA. 
Miscellaneous: Allen-Bradley 8520-ENC4 Digital Servo Module is mounted in the component enclosure. The 8520-ENC4 functions as a high-speed servo processor. The control sends positioning and velocity data to the 8520ENC4 servo module where it is processed to generate the necessary pulse width modulated (PWM) command signals. The 8520-ENC4 servo module provides battery backup for the absolute encoder position register and an analog velocity command signal for a servo that is not using a digital servo amplifier.
