It lands in a CS1W I/O slot the same way the surrounding digital and specialty modules do, which is the part of the decision an integrator locks in first when sizing a CS1 rack. ## Channel density and signal class Sixteen analog inputs on a single backplane slot is the headline density figure; the same CS1W form factor is shared by the 8-channel CS1W-PDC55, the 8-channel CS1W-PTS56, and the 4-channel CS1W-PTS02, so when a BOM line calls for fewer channels the spec-compatible siblings drop in without changing the slot or the screw-termination layout. ## Panel-side fit Backplane mounting with screw terminations keeps field wiring on a familiar Phoenix-style landing and lets the module share a row with other CS1W I/O on the same DIN segment. Operating range of 0°C~55°C covers the inside-envelope environment typical of a CS1 panel; storage extremes are wider, so the figure that governs a running cabinet is the operating span, not the handling limit. ## Compliance marks on record The approval marks listed for the module are CE and cULus; the procurement file is limited to CE and cULus certificates for this order code. ## Sourcing posture","metaTitle":"Omron CS1W-AD161 Analog Input Module, 16 ch","metaDescription":"Omron CS1W-AD161 CS Series backplane analog input module, 16 channels, screw terminations, CE/cULus.
