What lands in the rack
The Omron CS1W-PTS52 is a 4-channel analog input module that seats on the CS Series backplane and lands its field wiring on screw terminals, so it drops into an existing CS1W I/O slot without re-engineering the rack. Approval set is CE and cULus — enough for the usual NA panel shop and EU machine build, and what shows up on the nameplate for the audit trail. Operating envelope is 0°C to 55°C, which is the standard CS1W cabinet-interior window — no derating curve to chase for an enclosed control panel.
Lifecycle and supply posture
Product status reads Active in the OMRON lifecycle record, so the BOM line is live and the module is specified into the rack, not chased through last-time-buy or surplus channels. With status Active, the sourcing move is the usual one: RFQ against your committed quantity, lead time driven by OMRON's published schedule — no broker detour, no EOL clock to race.
Same-rack second source?
Three same-class peers in the CS1W input-module family — CS1W-PTW01, CS1W-PTS12, and CS1W-PTS01-V1 — share the 4-channel analog count, the CS1W backplane mount, the screw-termination style, and the 0°C to 55°C operating window with the PTS52. None of those peers is listed as a confirmed drop-in alternate on a wiring-pinning basis — the channel-by-channel signal type and pin map have to be reconciled against the project drawing before a panel swap is signed off.
Field-handling note
Screw-termination field wiring means the standard strip-length and torque practice for the CS1W family applies; no spring-cage or special tooling change for the swap-in.
