Product Overview
The Omron CP1E-N40SDR-A is a Class-N application-model compact PLC from the CP1E-N series with 40 I/O points, 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 24 DC inputs at 24 VDC sink/source and 16 SPST-NO relay outputs at 250 VAC, 2 A resistive. Power supply is 100 to 240 VAC, 85 to 264 VAC operating, 50 VA max. Program capacity 8K steps, data memory 8K words, and a 0.30 A external 24 VDC supply powers the sensors directly.
Built-in serial ports are USB Type-B for CX-Programmer and RS-232C for an NS-series HMI. The high-speed counter runs at 100 kHz; pulse output at 100 kHz for one stepper or servo axis. Real-time clock built in. The 150 x 90 x 85 mm DIN-rail body weighs about 660 g. The CP1E-N30DR-A sibling is the 30 I/O version with 18 in / 12 out; the CP1L-M40DR-A is the CP1L alternative with Ethernet.
Key Features
- CP1E-N-series Class-N application-model PLC, 40 I/O points: 24 DC inputs at 24 VDC sink/source and 16 SPST-NO relay outputs at 250 VAC / 2 A

- 8K-step program capacity, 8K-word data memory, real-time clock, 100 kHz high-speed counter and 100 kHz pulse output on one axis
- Built-in USB Type-B for CX-Programmer and built-in RS-232C for NS-series HMI or Modbus-RTU peripheral, expandable up to 3 CP1W units
- SKU: CP1E-N40SDR-A
- Series: Omron CP1E-N-series Class-N application-model compact PLC
- Voltage: 100 TO 240 VAC
Best-Fit Applications
- Standalone control of a small parts-filling machine where 24 inputs read sensors and 16 relays drive 24 VDC solenoid valves and 250 VAC motor contactors
- Pump-sequencing panel for a water-treatment skid where the built-in real-time clock alternates pump run-hours and relays switch 2 A motor contactors
- Spare replacement on a packaging line where the previous CP1E-N30DR-A was upgraded to 40 I/O and the ladder program loads over the USB Type-B port
Buying Checklist
- Pick the CP1E-N40SDR-A for a 40 I/O AC-powered CP1E-N PLC with 24 DC inputs, 16 relay outputs at 2 A, and built-in USB plus RS-232C.
- Pick the CP1E-N40DT-D instead when the cabinet needs the same 40 I/O with 16 NPN transistor outputs instead of mechanical relays at faster switching speeds.
- Pick the CP1L-M40DR-A instead when the application needs faster scan time, built-in Ethernet, or a Modbus-RTU master on the RS-485 option board.

FAQ for CP1E-N40SDR-A
What is the Omron CP1E-N40SDR-A used for?
It is the CP1E-N-series Class-N application-model PLC with 24 DC inputs, 16 relay outputs, 8K steps of program, and built-in USB plus RS-232C. The 100-240 VAC supply makes it the typical drop-in for a small standalone machine panel that already has AC mains available.
CP1E-N40SDR-A vs CP1E-E40DR-A - what is the difference?
Both have 24 DC inputs and 16 relay outputs on the same 40 I/O body. The -N version is the basic Class-N model without built-in analog I/O; the -E version is the enhanced Class-E model with built-in analog inputs and outputs and an extra RS-485 port. Pick the -N when the cabinet only needs discrete I/O; pick the -E when the application also reads analog sensors or drives analog valves.
Does the CP1E-N40SDR-A have Ethernet?
No. The CP1E-N40SDR-A has USB Type-B for programming plus RS-232C for an NS-series HMI or Modbus-RTU peripheral. For Ethernet, pick the CP1L-M40DR-A or CP1E-N40DDT-D, which adds a 10/100 Mbps Ethernet option board slot. The CP1W-CIF01 option board adds an RS-232C port and the CP1W-CIF11 adds RS-422A / RS-485.
Can the CP1E-N40SDR-A drive a 2 A motor contactor directly?
Yes. Each of the 16 relay outputs is rated 250 VAC at 2 A resistive and 30 VDC at 2 A resistive. A 2 A motor contactor coil at 24 VDC or 230 VAC lands directly on the relay contacts. For larger motors, drive the contactor coil from the relay and let the contactor switch the motor power.
