The input delay is configurable from 0 to 32 ms (off and on), which lets you debounce noisy limit switches or proximity sensors right at the module without a separate filter block in the logic. ## Approvals and compliance — marine and industrial ready The CJ1W-ID231 carries CE, cULus, Lloyd, and NK approvals, so it is accepted in both industrial control panels and marine applications (Lloyd's and Nippon Kaiji Kyokai classification). That saves a separate approval hunt when the panel ships to a shipyard or a cULus-required site.","metaTitle":"Omron CJ1W-ID231 Input Module, 32 Digital Points, 24 VDC","metaDescription":"Omron CJ1W-ID231 digital input module for CJ Series PLCs. 32 points, 24 VDC, 4 mA, PNP/NPN selectable, 0–32 ms delay.
