Omron CJ2M-CPU31 CJ-Series PLC CPU with Built-In EtherNet/IP

$0.00

Omron CJ2M-CPU31 is a CJ2M-series programmable controller CPU with built-in EtherNet/IP communications, commonly used in compact and mid-size machine automation systems.

This listing is built around the exact manufacturer reference CJ2M-CPU31. Industrial automation components often share nearly identical housings across a product family while differing in voltage, I/O type, protocol, firmware, connector style, current rating, safety function, sensing method, or lifecycle status. Using the exact model number helps maintenance, engineering, and purchasing teams avoid ordering a visually similar but incompatible component.

Key product details

  • Manufacturer: Omron
  • Model: CJ2M-CPU31
  • Platform: CJ2M / CJ-Series
  • Product type: PLC CPU
  • Ethernet: Built-in EtherNet/IP
  • Program capacity: 5K steps class
  • I/O architecture: CJ-Series modular I/O
  • Programming: CX-Programmer / CX-One
  • Primary role: Machine and process control
  • Lifecycle context: Installed-base / legacy automation platform

Common applications: Packaging machines, conveyors, material handling, assembly systems, process skids, inspection equipment, and existing Omron CJ-Series installations requiring exact replacement hardware.

Compatibility and ordering note: Confirm complete CPU model, unit version, program backup, memory card, CJ-Series I/O and specialty modules, EtherNet/IP addressing, serial options, CX-Programmer project version, PLC setup, data memory retention, and whether migration to a newer NX/NJ platform is acceptable.

Why buyers source the exact part: Exact-MPN replacement is often the fastest path when a production asset is down, an OEM BOM specifies a particular device, a controls project depends on an installed firmware or network configuration, or a plant wants to preserve existing wiring and programming. Even when a newer replacement exists, changing platforms can introduce engineering, commissioning, documentation, and downtime costs.

Sourcing through Corwin Solutions: Corwin Solutions sources industrial automation, electrical, controls, and MRO components by exact part number and can also review acceptable replacement options when the original model is constrained, obsolete, discontinued, or difficult to locate. Send the required quantity, preferred condition, ship-to destination, and required delivery date. For replacement applications, a clear photo of the installed nameplate and any known series, firmware, network, motor, connector, parameter, or machine information can help confirm the request before quotation. Availability, condition, exact configuration, pricing, and lead time are confirmed at the time of quote.
