Product Overview
The Omron CP2E-N20DR-D is the smallest member of the CP2E Network series — a 20-point compact PLC with 12 DC inputs, 8 relay outputs, 24 VDC supply, and a built-in Ethernet port. manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
It suits small machines that need network communication (Modbus/TCP, FINS/TCP, or Host Link over Ethernet) without the cost of a CJ-series PLC. The relay outputs can switch up to 2 A at 250 VAC, so they drive small motor contactor coils directly without an interposing relay.
The CP2E-N20DR-D ships from Xiamen with full datasheet documentation. Plan one slot each for the optional CP2W serial or analog board on the front and one CP1W expansion unit on the right.

- SKU: CP2E-N20DR-D
- Series: CP2E (Network tier)
- Voltage: 24 VDC
- I/O: 20 I/O
Best-Fit Applications
- Standalone temperature-control panel with NA5 HMI over Ethernet
- Pump or HVAC sub-panel slaved to an upstream CJ2M
- Small packaging machine with Modbus/TCP SCADA
Buying Checklist
- Pick CP2E-N60DT1-D for 60-pt PNP outputs
- Pick CP2E-N20DR-D for 20-pt Network DC PLC (this SKU)
- Pick CP2E-S20DR-D if Ethernet is not needed

FAQ for CP2E-N20DR-D
How many Ethernet ports does it have?
One. Although the Network tier typically suggests two, the N20 size ships with a single 10/100 Base-TX port. Larger CP2E-N sizes (N30, N40, N60) typically have two ports with an internal switch for panel daisy-chain. If a quote lists N20 as 'dual Ethernet', it is confusing N20 with N30.
Does it have a USB programming port?
No. Programming goes through Ethernet using CX-Programmer. If you need USB on a 20-point CP2E, there is no current option — step up to the 30-point CP2E-N30DR-D, which has a built-in peripheral USB 2.0 Type-B port. Or add a CP2W-CIFD1 RS-232C option board and program over serial Host Link at 115.2 kbps.
What expansion can I add?
Two slots total: one CP1W unit on the right (for example, CP1W-16ER for 16 extra relay outputs or CP1W-20EDR1 for 12 in / 8 out) for up to 32 total I/O, and one CP2W option board on the front (CP2W-CIFD1 for RS-232C, CP2W-CIFD2 for RS-422/485, or CP2W-AD/DA for analog). The analog option board and a CP1W analog unit cannot both be used at the same time.
What battery does it need?
None for basic operation. The program is stored in non-volatile memory, so a power cycle does not lose it. The optional CP2W-BAT02 backup battery is only needed to retain the DM area, retained CIO words, counter values, and real-time clock when the supply is removed. If you never need retained data, you can leave the battery slot empty.
