Genuine Omron SYSMAC CJ2M industrial PLC system built around the CJ2M-CPU33 programmable controller, supplied as the complete assembled configuration shown in the photos.
The system is used, tested and fully working. It has been removed from industrial equipment and shows normal cosmetic signs of previous installation and use.
This is substantially more than a bare CPU. The assembly includes the power supply, CJ2M CPU with integrated EtherNet/IP communications, an additional CJ1W Ethernet communication module and a sizeable bank of digital input and output modules. It is therefore suitable both as a complete replacement PLC assembly and as a valuable source of compatible CJ-series spare modules.

3 × Omron CJ1W-OD212 – 16-point digital output modules
-
4 × Omron CJ1W-ID211 – 16-point 24 VDC digital input modules
- Terminal blocks / front connectors as fitted and shown
- Complete assembled PLC configuration shown in the photographs
CJ2M-CPU33
The CJ2M-CPU33 is part of Omron's CJ2M machine automation controller family. The CPU33 version provides 20K program steps and is one of the CPU3x variants with integrated Ethernet capability. Omron specifies the CPU3x series for machine automation applications requiring compact architecture, communications and CJ-series I/O compatibility.
The CPU includes:
- Built-in EtherNet/IP
- 10BASE-T / 100BASE-TX Ethernet
- USB peripheral programming interface
- Battery-backed memory functions
- 20K-step user program capacity
- Support for CJ-series Basic I/O, Special I/O and CPU Bus Units
- DIN-rail modular architecture
CJ1W-ETN21 Ethernet unit
The fitted CJ1W-ETN21 provides an additional industrial Ethernet interface supporting 100BASE-TX, FINS communications, TCP/IP and UDP/IP communications, FTP server functionality and socket services.
This makes the complete rack particularly useful for replacement or maintenance of existing Omron CJ1/CJ2 installations where the original PLC configuration needs to be preserved.
Digital I/O configuration
The rack contains:
4 × CJ1W-ID211 input modules
These are CJ-series 16-point digital input modules for 24 VDC industrial signals.
Total from the four modules:
64 digital input points
3 × CJ1W-OD212 output modules
These are CJ-series 16-point transistor digital output modules.
Total from the three modules:
48 digital output points
That gives the pictured expansion rack a substantial discrete I/O capacity in addition to the CPU and communications hardware.
Condition
Used – tested and fully working.
The modules show normal cosmetic wear, scratches and marks from industrial installation. No attempt has been made to cosmetically refurbish the equipment.
Connectors, terminal blocks and modules are supplied as shown in the actual photographs.
This is the complete assembled unit shown, not just the CJ2M CPU.
