      PRODUCT & ORDER FAQS

      Questions buyers ask about 1794-IB16

      • How can I confirm the exact 1794-IB16 unit?

        Match the complete catalog number, series and revision on the nameplate to the approved I/O list; do not identify it by family name alone.

      • Which FLEX I/O hardware is needed with this module?

        It installs on a compatible 1794 terminal base and communicates through a FLEX I/O adapter. Confirm the exact base and adapter combination for the existing assembly.

      • What field signals can the input channels monitor?

        The module has 16 current-sinking inputs for 24 V DC signals; Rockwell specifies a 10–31.2 V DC on-state range and 8.0 mA nominal input current.

      • What should be checked before energizing a replacement?

        Verify keyswitch position 2, field-supply polarity, commons, wiring, selected input filter and each controller tag against the approved schedule.

      • Can the listed stock quantity be treated as guaranteed?

        No. Ask for a written quotation to confirm current quantity, supplied condition, inspection scope and included accessories.

      • What warranty is offered?

        Moore Automated’s stated warranty is one year; confirm the applicable coverage and terms in the written quotation.

      • When are final shipping measurements available?

        The page separates installed or bare-item reference measurements from packed figures; final packed dimensions and gross weight are confirmed after packing.

      • What details help obtain a replacement quotation quickly?

        Provide quantity, full catalog number and series, existing terminal base and adapter, destination country and required delivery date.
