Information About 8520-ASM3

The 8520-ASM3 analog servo board is engineered for use with Allen-Bradley CNC systems and supports up to three independent motion control axes. It provides ±10V analog output with 1.22 mV resolution, ensuring accurate positioning and smooth axis movement. The board includes three D-sub connectors and integrates firmware upgrades for enhanced system functionality. Though discontinued by the manufacturer, it remains a valued module in legacy CNC systems requiring analog servo output.

Key Features:

  • 3-Axis Motion Control: supports analog control for three servo axes with firmware-enhanced functionality.
  • High Output Precision: ±10V output range with 1.22 mV resolution and ±1 LSB gain error for smooth, accurate movement.
  • Optimized Timing: features a 500 Hz sampling rate and 8.25 ms conversion time to ensure consistent servo feedback.
  • Low Offset Voltage: maintains a maximum output offset of 500 mV and current draw limited to 5 mA per axis.
  • Legacy CNC Compatibility: specifically designed for integration with Allen-Bradley 9/260 and 9/290 CNC controllers.
  • Discontinued Status: no longer manufactured but supported in existing installations with backward-compatible firmware.

The 8520-ASM3 delivers precise analog servo control across three axes, combining legacy CNC integration with fine-tuned output characteristics for industrial motion applications.
