The 1746-NI16I is a discontinued Allen-Bradley SLC 500 16-point analog current input module, meaning you'll find it from surplus/new-old-stock suppliers like PLC Hardware (around $444+), eBay (from ~$375+), or Radwell (>$3,500+ for new), with prices varying widely by condition (new/used) and supplier, but it's no longer sold by Rockwell Automation directly as of late 2024, requiring searches on industrial parts resellers for good deals.
