Product Overview
The Omron CP2E-N40DR-D is a CP2E N-series compact PLC with 24 DC inputs and 16 relay outputs. It runs from 24 VDC and integrates two Ethernet ports, making it suitable for small machines that need controller, HMI and supervisory communications without a separate two-port switch.
The controller provides 20 K steps of total program capacity, 16 K words of data memory and function-block programming. It has no built-in USB or serial port; use Ethernet for programming or add a supported serial option board when required.
Up to three CP1W expansion units can raise the local system to 160 I/O points. The six encoder input channels support frequencies up to 100 kHz, subject to the counter mode and wiring described in the manual. For a transistor-output version, compare CP2E-N40DT-D and CP2E-N40DT1-D rather than treating DT and DT1 as interchangeable.
Key Features
- 24 DC inputs and 16 relay outputs on a 24 VDC supply
- Two built-in 10/100BASE-TX Ethernet ports; no built-in USB or serial port
- 20 K steps total program capacity and 16 K words of data memory
- Six encoder input channels, up to 100 kHz depending on operating mode
- Up to three CP1W expansion units and 160 maximum local I/O points
- SKU: CP2E-N40DR-D
- Series: CP2E N-series compact PLC
- Voltage: 24 VDC
- I/O: 24 I/O
Best-Fit Applications
- Compact machine control with relay outputs operating contactors, pilot relays or other suitably rated loads.
- HMI and SCADA connectivity using the two built-in Ethernet ports.
- Replacement or expansion of a small PLC system that needs up to three CP1W expansion units.
Buying Checklist
- Choose CP2E-N40DR-D for 40 integrated I/O points, relay outputs, 24 VDC supply and built-in Ethernet.
- Choose a DT or DT1 model only after confirming transistor output polarity and wiring; DR is the relay-output variant.
- Include any serial option boards and CP1W expansion units in the compatibility check before requesting a quotation.

FAQ for CP2E-N40DR-D
Does CP2E-N40DR-D have built-in USB or serial ports?
No. It has two Ethernet ports and no built-in USB, RS-232C or RS-485 port. Programming can use Ethernet; serial communications require a supported option board.
What is the difference between CP2E-N40DR-D and CP2E-N40DT-D?
DR denotes 16 relay outputs. DT denotes a transistor-output variant. Do not assume DT and DT1 have the same output polarity; confirm the exact wiring in the CP2E manual.
How many expansion units does CP2E-N40DR-D support?
Up to three CP1W expansion units, with a maximum of 160 local I/O points. Check each expansion unit's compatibility and power budget for the complete configuration.
How fast are the CP2E-N40DR-D high-speed counters?
Omron lists six encoder input channels and a maximum frequency of 100 kHz. The usable frequency and channel count depend on the selected counter mode and input wiring, so configure them from the CP2E manual rather than a single headline figure.
