Omron CP1E-N40DR-A

The Omron CP1E-N40DR-A is a step up from the basic “E” series we sometimes see. Because it’s an “N” type (Application Model), it has more “brains” and better communication features, making it a favorite for small-to-medium machine automation.

Here is the essential data for your technical and sales records:

⚙️ Technical Specifications

• I/O Count: 40 Total (24 Inputs / 16 Outputs).

• Output Type: Relay (The “R” in the name).

• Power Supply: 100 to 240V AC (The “A” at the end).

• Memory: 8K steps program capacity and 8K words data memory (4x more than the basic E-type).

• Communication: * Built-in USB for programming.

  • Built-in RS-232C port (9-pin) for connecting to HMIs or barcode readers.

• Clock: Features a Built-in Real-Time Clock (RTC), which is crucial for systems that need time-stamping or scheduled operations.

💡 Key Selling Points

• Versatility: Unlike the basic models, this “N” version can be expanded. You can add up to 3 expansion units (like the CP1W series) to increase I/O or add analog capabilities.

• Reliability: Relay outputs are robust for switching heavier loads directly (up to 2A), which is common in older industrial panels.

• Programming: It uses the standard CX-Programmer (part of CX-One), making it easy for most automation engineers to work with.

💰 Market Status (2026 Update)

• Lifecycle: Omron has officially moved toward the CP2E series as the successor. However, the CP1E-N40DR-A remains in extremely high demand as a “spare part” to avoid rewiring old panels.
