A 1746-NI16I sitting in its original sealed Allen-Bradley carton since roughly 1998, per the date code on the box label. Sixteen isolated 4-20 mA input channels — the isolated version, which mattered enormously in the paper-mill and refinery jobs where ground loops made the non-isolated NI16 unusable.
The card is single-slot and mates with any 1746 chassis (SLC 500/03, 04, 05). Rockwell classified it lifecycle-end in 2019 and end-of-serialization in 2022. Documentation, foam, and static bag all present.
We don't often see a truly untouched analog card of this vintage. Photographs on request.
