The CS1W-ID261 is a 64-point digital input module from the CS1W series, designed for backplane mounting in CS Series PLCs. It uses a rectangular connector for I/O wiring and carries approvals CE, cULus, Lloyd, and NK. With 64 inputs, it suits medium-to-high-density discrete sensing in automation lines.
Product status is listed as Active, but the lifecycle stage is flagged as end-of-life phase. This means Omron may transition this module in the medium term. For procurement planning, locking in a last-time-buy window or securing a successor part de-risks a BOM freeze. The module remains available through distribution; volume or long-term support should be quoted against an RFQ early.
Integration & Panel Fit
Backplane mounting places the module directly into the CS-series backplane slot — no DIN rail or additional brackets needed. The rectangular connector provides a dense, reliable termination for 64 digital inputs; ensure panel layout accounts for the connector footprint and cable strain relief.
