Why Engineers Specify This Model
- 40 I/O in a Compact Footprint – The N40 variant provides the highest built-in I/O count in the CP1E-N range, eliminating the need for an immediate expansion unit in most SME applications.
- Relay Output Versatility – Relay outputs switch both AC and DC loads without external interface relays, simplifying panel wiring and reducing BOM cost.
- AC Power Supply – Direct connection to 100–240 VAC eliminates the need for a separate 24 VDC power supply in many installations.
- RS-232C + USB Dual Port – Enables simultaneous HMI communication and laptop programming without a port-switching adapter.
- Expandable Architecture – Up to 3 expansion units allow the system to grow from 40 to a maximum of 100 I/O points as machine requirements evolve.
- CX-Programmer Compatibility – Fully supported by OMRON’s industry-standard IEC 61131-3 programming environment.
- Proven Global Installed Base – The CP1E series is one of OMRON’s highest-volume compact PLC families, ensuring long-term parts availability.

Application-Specific FAQ
Q: Can the CP1E-N40SDR-A control a servo drive directly?
A: The N-type CP1E does not support built-in pulse output for servo positioning. For servo axis control, specify the CP1E-N40SDT-A (transistor output) or upgrade to the CP1L/CP2E series with pulse output capability.
Q: How many expansion units can be connected?
A: Up to 3 CP1E Expansion I/O Units, bringing the maximum system I/O to 100 points.
Q: Is the CP1E-N40SDR-A compatible with OMRON NS-series HMIs?
A: Yes. The built-in RS-232C port supports direct connection to NS-series HMIs using the OMRON Host Link / NT Link protocol.
Q: What is the difference between CP1E-N40SDR-A and CP1E-N40SDT-A?
A: The R suffix denotes relay output; the T suffix denotes transistor (NPN) output. Relay outputs handle higher load currents and both AC/DC loads; transistor outputs are required for high-speed pulse output applications.
Q: Does Konmask.com ship internationally?
A: Yes. We ship worldwide via DHL, FedEx, and UPS. Export documentation including commercial invoice and packing list is provided for customs clearance.
