64 points, one slot
The CJ1W-ID261: 64-point digital input module for Omron CJ series. DIN rail mount, rectangular connector. Active product — no end-of-life surprises. Drops into a CJ rack and fills 64 inputs in a single slot, cutting the number of modules needed for high-channel-count builds.
Density choice
The CJ1W-ID232 and CJ1W-ID231 pack 32 inputs in the same form factor — useful when half the density is enough. But the CJ1W-ID261 gives you twice the I/O in the same footprint, with identical mounting and approvals. Mix them in a rack if some slots need fewer points.
