Product Overview
The Omron CJ2H-CPU65-EIP is the CJ2H-series flagship PLC CPU with built-in EtherNet/IP, manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
It runs ladder and structured-text programs out of 50K steps of user memory with 160K words of data memory. The LD instruction executes in 0.016 microseconds, fast enough for high-speed packaging and motion control. Three on-board ports handle EtherNet/IP, RS-232C serial, and USB programming. Up to 2,560 local I/O points and 40 Units across three Expansion Racks.
For a smaller mid-range CPU with built-in I/O, pick the CJ2M-CPU35. Programming uses CX-One / CX-Programmer. Production of the CJ2H-CPU65-EIP is planned to end on 2027-03-31; the modern Sysmac NJ-series replacement is the NJ501-1300. The 100K-step and 250K-step siblings share the same body and EtherNet/IP port.
Key Features
- CJ2H-series CPU with 50K-step program memory, 160K-word data memory, 0.016 microsecond LD execution time
- Built-in EtherNet/IP, Ethernet TCP/IP, RS-232C serial, and USB programming ports
- Up to 2,560 I/O points across the CPU Rack and three Expansion Racks, up to 40 Units
- Backward-compatible with existing CJ1-series I/O and Expansion Racks for in-place upgrades
- SKU: CJ2H-CPU65-EIP
- Series: CJ2H-series (CJ2 high-performance platform with built-in EtherNet/IP)
- I/O: 2 I/O
Best-Fit Applications
- Line control on a high-speed bottling line where the CJ2H-CPU65-EIP runs 50K steps of motion and recipe code over EtherNet/IP to ten R88D-1SN drives
- Mid-size machine control where the cabinet reuses existing CJ1W-PA power supplies, CJ1W-ID211 inputs, and CJ1W-OC211 outputs from a previous CJ1M install
- Spare replacement on a process skid where the original CJ1M-CPU23 is upgraded for the CJ2H-CPU65-EIP to gain built-in EtherNet/IP for a remote SCADA tie-in
Buying Checklist
- Pick the CJ2H-CPU65-EIP for a CJ2H flagship CPU with built-in EtherNet/IP at the 50K-step program memory size.
- Pick the CJ2H-CPU66-EIP instead when the cabinet needs 100K steps of user memory on the same built-in EtherNet/IP body.
- Pick the CJ2H-CPU68-EIP instead when the program must exceed 100K steps and the application needs the 250K-step EtherNet/IP flagship.

FAQ for CJ2H-CPU65-EIP
What is the Omron CJ2H-CPU65-EIP used for?
It is the CJ2H-series flagship CPU with built-in EtherNet/IP, used in mid-size automation cells that need fast scan times and network connectivity. It runs ladder and structured-text programs out of 50K steps with 160K words of data memory and up to 2,560 I/O points. It is a drop-in upgrade for CJ1M-CPU2x installs that adds EtherNet/IP without an extra CJ1W-ETN21 module.
CJ2H-CPU65-EIP vs CJ2H-CPU66-EIP - what is the difference?
Both share the same CJ2H body, built-in EtherNet/IP, RS-232C, USB, 2,560 I/O, 0.016 microsecond LD execution time, and 0.82 A current draw. The -CPU65-EIP has 50K steps of program memory and 160K words of data memory; the -CPU66-EIP has 100K steps and 160K words. Pick the -65 for cells under 50K steps; pick the -66 when the program needs the extra 50K.
Does the CJ2H-CPU65-EIP need an Expansion Rack?
Not always. The CJ2H-CPU65-EIP supports up to three Expansion Racks and 40 Units total, but most cells fit on the CPU Rack alone. Add a CJ1W-IC101 I/O Control Unit on the CPU Rack and a CJ1W-II101 I/O Interface Unit on each Expansion Rack when the cell exceeds 10 Units on the CPU Rack.
Can the CJ2H-CPU65-EIP be programmed in Sysmac Studio?
No. The CJ2H-series uses CX-One / CX-Programmer for ladder, structured text, and function blocks. Sysmac Studio programs the NJ / NX Sysmac controllers only. For an NJ-series upgrade path that uses Sysmac Studio, pick the NJ301-1200 (4 axes) or NJ501-1300 (16 axes).
Is the CJ2H-CPU65-EIP still in production?
Production of the CJ2H-CPU65-EIP is planned to end on 2027-03-31. Hengyixin stocks the part for the existing install base and can ship the modern NJ5 replacement NJ501-1300 alongside the legacy CPU for phased cabinet upgrades.
