Technical FAQs

  1. What is the primary function of the NIDI01 module?
    It terminates and interfaces field digital input signals to the INFI 90/Network 90 control modules.

  2. Which digital signals are supported?
    Discrete digital inputs, pushbutton/switch signals, and contact closures.

  3. Where is it installed?
    Within field termination panels or control system racks.

  4. Does it perform logic processing?
    No — logic execution occurs in the controller or logic solver; NIDI01 only provides termination and interface.

  5. Can it operate in harsh industrial environments?
    Yes — when installed in proper industrial enclosures.

  6. Does it provide electrical isolation?
    Yes — protects the control system from field noise and disturbances.

  7. Does it require calibration?
    No — digital input signals do not require calibration.

  8. How does it aid maintenance?
    Centralized terminals allow easy testing, signal verification, and troubleshooting.

  9. Is it compatible with modern ABB systems?
    Primarily designed for INFI 90, but can integrate with Network 90 installations as needed.

  10. Which industries commonly use this module?
    Petrochemical, power generation, water/wastewater treatment, and manufacturing plants.
