Important Technical Questions

• Can inputs and outputs work at the same time?
  Yes. Both input channels and both output channels can operate simultaneously.
• What is the difference in resolution?
  Inputs have 16-bit resolution for high accuracy. Outputs have 14-bit resolution.
• How do I set voltage or current mode?
  You configure each input channel through software. No physical switches are needed.
• What controllers support this module?
  It works with SLC 500 controllers and can also be used with CompactLogix and ControlLogix systems.
• Is special wiring needed?
  Use shielded cable like Belden #8761. Keep wires away from power lines to avoid noise.
