The Omron CP1L-EM40DT-D is a compact PLC with 24 digital inputs and 16 solid state outputs, running on 24 VDC and featuring 32K words of memory, on-board Ethernet, and battery backup for program retention.
The 24 digital inputs and 16 solid state outputs provide direct control. Solid state outputs handle high-frequency switching without relay wear. 32K words of memory accommodates a mid-size logic program and data tables. The battery backup retains program and data on power loss, so you don't lose configuration after a line outage. On-board Ethernet allows direct connection to a plant network or a SCADA system, and the option-card slot adds alternative fieldbus (like DeviceNet, PROFIBUS, or serial) when needed. Expandable to 3 additional modules — you can add analog I/O, temperature inputs, or extra discrete points without swapping the base unit.
How it compares in the CP1L family
The CP1L-EM30DT-D offers 18 inputs and 12 solid state outputs — a lower point count for smaller applications. If you need relay outputs instead of solid state, the CP1L-EM30DR-D (18 in, 12 relay out) is the sibling to consider. Both are in the same chassis and mounting, with identical memory and Ethernet features.
Mounts on DIN rail or chassis; no front display, so all programming and monitoring is done via CX-One software over Ethernet or USB. The backup battery is user-replaceable and extends the retention time during power-off periods. Operates at 0°C to 55°C, which covers most cabinet environments. The 24 VDC supply is standard across industrial panels — no separate power supply module needed beyond the main bus.
