Frequently Asked Questions (FAQ)

  • How many voltage inputs does this module have?
    The 1790D-TN4V0 provides four independent voltage input channels.
  • What voltage range can it measure?
    It measures standard 0 to +10 Volt DC signals from sensors and transmitters.
  • What is the sampling rate or conversion time?
    Each channel converts in 10 milliseconds for accurate data acquisition.
  • Does it need periodic calibration?
    No, this Allen-Bradley module is factory set and maintenance-free.
  • What is the input impedance?
    It features high 500 KΩ input impedance to avoid signal distortion.
  • Can I expand the system with more modules?
    Yes, you can add up to two expansion modules to this base unit for more I/O.

This input module is part of the reliable Allen-Bradley 1790 DeviceNet series for industrial automation.
