The Omron CP1E-N40DT-D (CP1EN40DTD) is a high-performance "Application Model" (N-Type) CPU unit within the CP1E series, specifically designed for machines requiring more sophisticated control than basic sequential logic. With 24 digital inputs and 16 transistor (sinking) outputs, the CP1E-N40DT-D provides a robust 40-point I/O base suitable for high-speed packaging, precision labeling, and multi-axis conveyor systems. This N-Type model is distinguished by its built-in RS-232C port and high-speed pulse functionality, offering engineers a cost-effective platform for applications involving Serial PLC Link communication, human-machine interface (HMI) integration, and basic motion control.
The CP1E-N40DT-D is powered by 24 VDC and features a high-speed processor capable of 1.1 µs logic execution. As an N-Type controller, it is significantly more capable than the E-Type basic models, featuring expanded memory and enhanced communication flexibility. It includes a built-in peripheral USB port for programming and an RS-232C port for serial communication.
The module is equipped with 24 inputs, of which 6 are high-speed counter inputs (up to 100 kHz), and 16 transistor outputs, with 2 supporting high-speed pulse outputs (up to 100 kHz). This hardware configuration allows for dual-axis positioning control and high-resolution encoder feedback. The "Sinking" output type (NPN) is the standard for Asian and North American markets, where the PLC switches the negative (0V) side of the load.

Q1: What is the primary difference between the CP1E-E and CP1E-N models?A1: The CP1E-N (including the N40DT-D) features a built-in RS-232C port and supports optional serial boards. It also offers a larger program memory and faster processing speeds compared to the basic E-Type models, which only feature a USB port.
Q2: How many axis of motion can this CPU control?A2: It features two built-in pulse outputs (100 kHz), allowing you to control two independent axes of motion (e.g., two stepper motors or servo drives) for simple X-Y positioning tasks.
Q3: Can I add more I/O to this 40-point unit?A3: Yes. The CP1E-N40 series can be expanded using CP1W expansion modules. You can add up to 3 expansion units, allowing you to incorporate analog I/O, temperature sensor inputs, or additional digital points as needed.
High-Speed Wiring: For the 100 kHz pulse outputs and counter inputs, always use shielded twisted-pair cables. To maintain signal integrity and prevent electromagnetic interference (EMI) from affecting positioning accuracy, ensure the shield is grounded at the PLC chassis ground terminal only.
Sinking Output Logic: Remember that the N40DT-D uses NPN sinking logic. The common terminal (COM) should be connected to the negative side of your power supply, and the load should be connected between the positive rail and the PLC output terminal.
Serial Communication Setup: When using the RS-232C port to connect an HMI or another PLC, ensure the DIP switches (located under the port cover) are correctly set for either "Host Link" or "No-Protocol" mode to match your communication requirements.
The CP1E-N40DT-D is an engineering "sweet spot" for machine builders who require 100 kHz motion control and serial connectivity without the higher price tag of the CP1H or CJ2 series. Its 150 mm width provides high I/O density on the DIN rail, while its 24 VDC power requirement simplifies the bill of materials for export machines. Furthermore, the ability to use standard USB cables for programming significantly lowers the barrier for field maintenance, as no proprietary cables are required for troubleshooting.
