The supplied catalog places SCXI-1104D in the SCXI category and describes it as a medium-voltage input module. That legacy description groups several model suffixes together and is not sufficient to establish specifications for the D suffix.
NI's official SCXI-1104 product page identifies SCXI-1104 without a D suffix, and its archived SCXI driver table lists SCXI-1104/C. These references do not establish SCXI-1104D specifications or software support.
Before purchase or integration, compare the physical unit and its documentation against the model marking, manufacturer label, complete part or assembly number, host-platform compatibility, hardware revision, and required software or driver support. This is especially important for legacy test-and-measurement hardware, where similarly named models can differ by revision, bus type, connector arrangement, supported accessories, or software generation.
This record currently has 2 supporting source references in the SOHO evidence set, including www.ni.com. Where a specification is not explicitly supported by those sources, it is intentionally left unconfirmed rather than inferred from a related model.
