Product Overview
The Omron CP1E-NA20DR-A is a CP1E-NA-series compact PLC with built-in analog I/O, 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.
The CPU has 12 x 24 VDC inputs, 8 x SPST-NO relay outputs at 2 A, 2 built-in analog inputs (0-10 V or 0-20 mA), and 1 built-in analog output (0-10 V or 4-20 mA) at 1/6000 resolution. Power supply is 100 to 240 VAC. Program capacity 8K steps, data memory 8K words, real-time clock built in.
Serial ports are USB Type-B for CX-Programmer and RS-232C for an NS-series HMI. One CP1W option-board slot supports RS-422A / RS-485, RS-232C, or Ethernet. Expansion is up to 3 CP1W units for 140 total I/O. Dimensions 150 x 90 x 85 mm, 660 g. The CP1E-N30DR-A sibling is the 30-I/O version without analog; the CP1E-E20DR-A is the more economical CP1E-E sibling without analog and with a smaller program.

Best-Fit Applications
- Standalone control of a parts-cleaning skid where 12 inputs read levels and the 8 relays drive pumps and valves
- Pump-sequencing panel for a water-treatment skid where the real-time clock alternates run-hours and the analog output drives a speed reference
- Spare replacement on a packaging line where the previous CP1E-N30DR-A is upgraded to add analog I/O without changing the wiring
Buying Checklist
- Pick the CP1E-NA20DR-A for a CP1E-NA compact PLC with 20 I/O, built-in analog inputs and output, and 100-240 VAC supply on the same body.
- Pick the CP1E-N30DR-A instead when the application only needs 30 digital I/O and does not need built-in analog I/O.
- Pick the CP1E-E20DR-A instead when the cabinet needs the more economical CP1E-E body without analog I/O and a smaller program.

FAQ for CP1E-NA20DR-A
What is the Omron CP1E-NA20DR-A used for?
It is the CP1E-NA-series compact PLC with 12 DC inputs, 8 relay outputs, 2 built-in analog inputs, and 1 built-in analog output on a 100-240 VAC supply. It is the typical drop-in for small standalone machines that already have AC mains and need both digital and analog I/O without adding a CP1W expansion unit.
CP1E-NA20DR-A vs CP1E-N30DR-A - what is the difference?
Both are CP1E-N-series compact PLCs with real-time clock, USB, and RS-232C. The NA20DR-A has 12 in / 8 out plus 2 analog in and 1 analog out at 1/6000 resolution. The N30DR-A has 18 in / 12 out, all digital, with no analog I/O. Pick the NA20DR-A when the cabinet reads analog sensors or drives an analog valve; pick the N30DR-A when the I/O is all digital.
Does the CP1E-NA20DR-A have Ethernet?
Not built in. The CP1E-NA20DR-A has USB Type-B for programming plus RS-232C for an NS-series HMI. Ethernet is available through the CP1W-CIF41 option board on the option-board slot. The CP1E-NA20DT-D and CP1W-CIF41 pair is the typical Ethernet drop-in for existing CP1E installs.
How many CP1W expansion units can the CP1E-NA20DR-A take?
Up to 3 CP1W expansion units, taking total I/O to 140 points. Common add-ons are the CP1W-AD041 (4 analog inputs), CP1W-DA041 (4 analog outputs), CP1W-TS001 (2 thermocouple inputs), CP1W-CIF11 (RS-422A / RS-485), and CP1W-40EDR (24 in / 16 relay out). The expansion units chain to the right of the CPU and are auto-detected by CX-Programmer.
Can the CP1E-NA20DR-A read a 4-20 mA pressure transmitter?
Yes. The 2 built-in analog inputs accept either 0-10 V or 0-20 mA, including 4-20 mA. Set the input range to 4-20 mA in the expansion / analog settings dialog in CX-Programmer and scale the raw value to engineering units. Resolution is 1/6000, or about 0.3 percent full scale.
