The OMRON CP2E-N30DR-A, also cataloged as the CP2E-N30 Programmable Controller, provides 18 digital inputs and 12 relay outputs in a 30-point CPU Unit configuration. It operates from a 100 to 240 VAC supply and belongs to the CP2E-N network model family.

Model and System Matrix

Hardware Specifications

The physical dimensions and maximum weight for the 30-point AC CPU configuration are specified by OMRON as 90 mm x 80 mm x 130 mm and 580 g maximum, respectively.

PLC Communication and I/O Architecture

The CP2E-N30DR-A is an N-type CP2E CPU Unit with two built-in Ethernet ports. Ethernet communication supports 10BASE-TX and 100BASE-TX operation with auto-negotiation and auto-sensing. The network interface supports TCP, UDP, ARP, ICMP ping, SNTP and DNS functions, with FINS, Socket, SNTP and DNS applications.

The CPU provides 18 built-in inputs and 12 relay outputs. For the N30 configuration, up to three CP1W-series Expansion I/O Units or Expansion Units can be connected, increasing the maximum I/O capacity to 150 points.

The CP2E-N30DR-A also supports high-speed counter functions, including up to three 100 kHz incremental pulse counters and two 100 kHz up/down or pulse-and-direction counter configurations, depending on the selected input mode.

Installation and Wiring Notes

Power Supply

• Connect the AC supply within the specified 100 to 240 VAC range.
• The specified operating voltage range is 85 to 264 VAC.
• Provide appropriate upstream circuit protection and disconnect means for the PLC power circuit.
• Do not apply 24 VDC to the AC-powered CP2E-N30DR-A.

I/O Wiring

• Verify the input common configuration before connecting field devices.
• Relay outputs should be wired according to the load voltage, current and contact requirements of the controlled equipment.
• Separate low-level input wiring from motor, contactor and high-current power conductors.
• Use suppression components appropriate to inductive loads connected to relay outputs.

Ethernet

• Use suitable 10BASE-TX or 100BASE-TX Ethernet cabling.
• Keep Ethernet cabling separated from high-energy switching conductors where practical.
• The specified maximum transmission distance between an Ethernet switch and node is 100 m.

Expansion

• The N30 configuration supports up to three CP1W-series Expansion I/O Units or Expansion Units.
• Verify the total I/O configuration and power budget before adding expansion hardware.
• Expansion units should be installed according to the CP2E hardware installation requirements.

Technical FAQ

• What is the power supply for CP2E-N30DR-A?

  The CPU Unit uses a 100 to 240 VAC, 50/60 Hz supply. Its operating voltage range is 85 to 264 VAC.

• How many built-in I/O points are provided?

  The CPU Unit provides 30 points in total: 18 digital inputs and 12 relay outputs.

• What type of outputs does this model use?

  CP2E-N30DR-A uses relay outputs. It is therefore different from the CP2E-N30DT-A transistor sinking-output version.

• What is the physical size of the CPU Unit?

  The 30-point AC CPU configuration measures 90 mm x 80 mm x 130 mm, equivalent to 9.0 cm x 8.0 cm x 13.0 cm.

• How much does the CPU Unit weigh?

  OMRON specifies a maximum weight of 580 g for CP2E CPU Units with 30 I/O points. This is the CPU Unit weight rather than a packed shipping weight.

• Can CP2E-N30DR-A be expanded with additional I/O?

  Yes. The N30 configuration supports up to three CP1W-series Expansion I/O Units or Expansion Units, with a maximum system I/O capacity of 150 points.

• Does the N30 model provide built-in Ethernet communication?

  Yes. N30 CPU Units provide two Ethernet ports supporting 10BASE-TX and 100BASE-TX communication, with a maximum switch-to-node transmission distance of 100 m.

• Is the relay-output model interchangeable with the transistor-output model?

  No. CP2E-N30DR-A and CP2E-N30DT-A have different output hardware. The DR-A version uses relay outputs, while the DT-A version uses transistor sinking outputs.
