I/O module

The 759-670 I/O module provides stepmotor and servo drive control in a compact 12 mm wide package.

Features & benefits

  • Supports two pulse output patterns — step/direction or incremental encoder

  • RS-422 interface; controlled by variable output frequency to 500 kHz

  • 16 fieldbus options

  • 24-bit resolution for positioning accuracy and 8 LEDs for status indication and diagnostics

  • Integrated control in fieldbus node (PLC or PC-based) eliminates separate motion controller
