The OMRON CP2E-N30DT1-D, also cataloged as the CP2E-N30 Programmable Controller, is a 30-point DC-powered CPU Unit with 18 digital inputs and 12 sourcing transistor outputs. It belongs to the CP2E-N Network model and operates from a 24 VDC supply.

Model Configuration

The CP2E-N30DT1-D is specifically listed by OMRON as the 30-point 24 VDC CPU with 18 inputs, 12 sourcing transistor outputs, 10K-step program capacity and 16K words of data memory.

Hardware Specifications

OMRON specifies 90 mm x 80 mm x 130 mm for 30-point CP2E CPU Units, with a maximum weight of 580 g. The DC-powered 30/40/60-point CPU group has a maximum system power-consumption rating of 20 W.

PLC Network and Sourcing Output Architecture

The CP2E-N30DT1-D belongs to the N-type Network model. Its N30 configuration provides two Ethernet ports supporting 100BASE-TX and 10BASE-TX communication, with auto-negotiation and auto-sensing. Supported network functions include TCP, UDP, ARP, ICMP ping, SNTP and DNS, with FINS and Socket applications available through the Ethernet interface.

The 12 transistor outputs use a sourcing configuration. This output arrangement should be matched with the electrical commoning and load-side wiring of the connected field devices. It is distinct from the CP2E-N30DT-D, which uses sinking transistor outputs, and the CP2E-N30DR-D, which uses relay outputs.

The N30 CPU configuration supports up to three CP1W-series Expansion I/O Units or Expansion Units. With three 40-point expansion units, the specified maximum I/O capacity is 150 points.

Field Installation Guidelines

DC Power Wiring

• Supply the CPU from a 24 VDC source within the specified 20.4 to 26.4 VDC operating range.
• Provide suitable upstream DC protection and isolation.
• Observe DC polarity when wiring the power terminals.
• The DC power supply circuit is not isolated between the primary and secondary DC power supplies.
• Consider the specified 30 A maximum inrush current for 20 ms during cold start when selecting the DC supply and protection devices.

Sourcing Output Wiring

• Confirm that the field load circuit is electrically compatible with sourcing transistor outputs.
• Verify the common wiring arrangement before energizing connected loads.
• Separate output wiring from high-current motor and contactor conductors.
• Use suitable suppression for inductive loads where required by the external circuit.
• Do not interchange sourcing and sinking output wiring without verifying the complete field circuit.

Ethernet Installation

• Use suitable twisted-pair Ethernet cable for the selected transmission speed.
• 100BASE-TX supports Category 5 or higher UTP/STP cabling.
• Keep Ethernet wiring separated from high-energy switching conductors where practical.
• The specified switch-to-node transmission distance is 100 m.

Panel Installation

• Mount the CPU inside the control panel according to the CP2E installation requirements.
• The fixed terminal block uses M3 terminal screws.
• Provide adequate clearance for wiring and thermal dissipation.
• Connect protective grounding to a system ground of 100 ohm or less.
