What lands on the bench
NX I/O slices mount to the right of an NX-series CPU or communications coupler on the same bus, so adding NX-IA3117 is an in-rack, slide-on expansion — no extra panel space or separate power supply beyond what the rack already supplies.
Where this class fits
NX-series expansion modules add analog and digital channels onto an NX CPU or a remote NX coupler, which is the typical pattern for machine builders who standardise on NX rather than mixing I/O families across cells. An NX-IA3117 slice brings its analog inputs into the same NX backplane, addressing and configuration land on the Sysmac Studio side the rest of the rack already uses.
Sourcing posture
Lifecycle stage is logged as current, which means the line is bought against an active RFQ rather than chased through last-time-buy or broker channels. A quote against the BOM line is the right next step for procurement — no need to spec a second-source footprint until Omron publishes otherwise.
