How it compares to CP1L-M30DT-A
The only functional difference between this 24 VDC version and the CP1L-M30DT-A is the supply voltage: 24 VDC versus 100–240 VAC. Every other spec — 18 inputs, 12 solid-state outputs, memory, expansion limit, mounting — is identical. If your panel already has a 24VDC bus, the -D version is the correct pick. If the design calls for AC power, swap to the -A variant; no other BOM adjustment needed.
Carries CE, cULus, Lloyd’s Register, and NK (Nippon Kaiji Kyokai) approvals. No RoHS or REACH documents are listed in the standard spec table, but these are typically provided by Omron upon request for the CP1L family.
