The Omron CP1L-L20DR-D is a compact PLC from the CP1L series, built for machine control with 12 digital inputs and 8 relay outputs on a 24 VDC supply. The 32K-word memory handles programs and retained data; battery backup keeps both intact through power cycles.
Mounting and expansion
Mounts on DIN rail or directly to a chassis panel. The base unit supports one expansion module — plan that slot for additional I/O or a serial/Ethernet card. The backplane connection is keyed so forced insertion doesn't damage pins. Programming uses CX-One software; the USB port provides the default connection. Option cards are available for additional communications.
Lifecycle and sourcing
Approvals include CE, cULus, Lloyd's Register, and NK — covering machinery directive, US/Canada safety listing, and marine classification. RoHS compliance is standard for this family; no separate declaration is needed for most procurement workflows.
