Product details

What the CS1W-AD161 is in the rack

The Omron CS1W-AD161 is a 16-channel analog input module that mounts on the CS Series backplane. 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

Frequently asked questions

What type is the CS1W-AD161 listed as?

It is listed as an Input Module on the CS1W line, with 16 analog input channels.

What series does the CS1W-AD161 belong to?

It belongs to the CS1W series and is for use with CS Series PLCs.

Will the CS1W-AD161 drop into a panel specified around the CS1W-PDC55 without rewiring?

It shares the CS1W backplane mounting, screw-termination style, approvals and operating temperature with the CS1W-PDC55, so the slot and field wiring land in the same place, but the AD161 is a 16-channel analog input module and the PDC55 is an 8-channel module, so the I/O map and channel assignment have to be reworked even though the physical landing matches.

What compliance documentation is on file for the CS1W-AD161?

The approval marks listed for this module are CE and cULus; the available record does not list RoHS, REACH or IEC documentation, so the procurement file should be limited to CE and cULus certificates for this order code.
