The rectangular-connector termination lands wiring in one MIL-style plug rather than per-point terminals, which matters when a panel-builder is retrofitting a dense I/O island into an existing CS chassis. Approvals on the module are CE, CSA, Lloyd, NK and UL — the same multi-jurisdiction set carried across the CS1W I/O family, so a declaration pack built around an adjacent CS1W card does not need a new compliance trail just to swap in the OD291. ## Where it sits against the rest of the CS1W I/O family Within the CS1W family the OD291 is the highest-density pure-output option in the cited set: 96 solid-state outputs on a single backplane slot. The mixed I/O peer CS1W-MD291 pairs 48 digital inputs with 48 solid-state outputs on the same form factor for panels that need both directions in one slot. The CS1WOD261 drops the density to 64 solid-state outputs in the same connector family for cabinets where the 96-point footprint is more than the wiring plan needs. All three ride the CS-series backplane and share the rectangular-connector termination, so slot and field-wiring class match across the family — the decision is density and direction, not bus compatibility. ## Integration checklist Before specifying the CS1W-OD291 into a CS1W rack, confirm three points against the existing panel: that the chassis has a free CS-series backplane slot, that the field wiring harness uses the rectangular-connector pinout matched to the 96-point output module, and that the CS-series CPU firmware revision in service supports the module's catalog number. The module ships in bulk pack rather than retail box, which is normal for the CS1W I/O line and does not affect panel layout.","metaTitle":"CS1W-OD291 CS1W Output Module, 96 solid-state","metaDescription":"Omron CS1W-OD291 CS1W-series 96-point solid-state output module for CS-series backplanes.
