The Omron CP1L-L10DR-A is a compact PLC from the CP1L series, offering 6 digital inputs and 4 relay outputs with a 100~240VAC power supply. Memory is 32K words, and the unit includes battery backup for program retention. No display, but USB communication is built in. Expandability is limited to 1 additional module, so plan the I/O count accordingly at the BOM stage.
Comparing with the 24 VDC sibling CP1L-L10DR-D
The CP1L-L10DR-D shares the same form factor, I/O layout (6 digital inputs, 4 relay outputs), 32K words memory, battery backup, and CX-One programming environment. The sole meaningful difference is the supply voltage: the -A version accepts 100~240VAC; the -D version requires 24VDC. That means they are not drop-in interchangeable — supply rewiring is needed. If your panel already has a 24VDC bus, the -D saves an AC-DC conversion step. If you’re sourcing from a BOM that specified -A, confirm the availability of AC power before switching to -D.
Mounting and expansion notes
Mounts on DIN rail or chassis. The unit is rated for 0°C to 55°C ambient. Expansion is limited to a single module, so the base unit must cover all needed I/O plus one expansion card. Communications are via USB only; no serial or Ethernet on board. If an option port is required, consider the -L20 variant which offers optional communications cards.
