Product Overview

The Omron CJ2H-CPU68-EIP is the top-end CJ2H 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.

Program capacity is 400K steps and data memory is 832K words (32K words DM plus 32K words EM across 25 banks). LD instruction execution is 0.016 us. Local I/O tops out at 2560 points across 40 Units and 3 Expansion Racks. Communication ports are EtherNet/IP, Ethernet TCP/IP, RS-232C and USB.

The CPU pulls 0.82 A at 5 VDC from the CJ power supply. Body size is 79.8 x 90 x 74.5 mm at 280 g. Ambient operating is 0 to 55 degC, 10 to 90 percent RH non-condensing. Production is planned to end 2027-03-31 per the official page. For a smaller program, pick the CJ2H-CPU65-EIP at 100K steps. For the next size down, use the CJ2H-CPU67-EIP at 250K steps.

Key Features

  • CJ2H CPU with built-in EtherNet/IP, 400K steps program, 832K words data
  • 0.016 us LD instruction execution, 2560 I/O points, 40 Units / 3 racks
  • Built-in EtherNet/IP, Ethernet TCP/IP, RS-232C and USB ports
  • 0.82 A at 5 VDC, 79.8 x 90 x 74.5 mm, 280 g
  • SKU: CJ2H-CPU68-EIP
  • Series: Omron CJ2H-series CPU with built-in EtherNet/IP
  • I/O: 2560 I/O

Best-Fit Applications

  • Plant-wide recipe server on a bottling line where 400K steps run the recipe and the EtherNet/IP port talks to 30 inverters and remote I/O drops
  • SCADA gateway where the CJ2H aggregates data from CJ1 and CP1E machines over EtherNet/IP and forwards batches to the MES
  • Spare replacement on a CJ2H rack where the old CPU failed and the CJ2H-CPU68-EIP drops onto the same slot with the same project

Buying Checklist

  • Pick the CJ2H-CPU68-EIP for a CJ2H CPU at 400K steps with built-in EtherNet/IP on a large automation cell.
  • Pick the CJ2H-CPU67-EIP instead when 250K steps is enough on the same EtherNet/IP body.
  • Pick the CJ2H-CPU65-EIP instead when 100K steps covers the program on the same EtherNet/IP body.

FAQ for CJ2H-CPU68-EIP

Is the CJ2H-CPU68-EIP still in production?
Production is planned to end on 2027-03-31 per the official EU page. Stock is available at Omron and at Hengyixin Automation in Xiamen for ongoing maintenance.
What software programs the CJ2H-CPU68-EIP?
CX-Programmer under CX-One or CX-One Lite. Existing CJ2H-CPU6x projects load with no change. For Sysmac Studio integration, step up to an NJ-series controller.
Does the CJ2H-CPU68-EIP need a battery?
Yes. The unit ships with a CJ1W-BAT01 battery that holds DM, EM and the real-time clock across power-downs. Replace the battery when the BATT LED lights.
What PSU pairs with the CJ2H-CPU68-EIP?
Any CJ1W or CJ2H compatible supply: the CJ1W-PA202 (100-240 VAC, 14 W), CJ1W-PA205R (100-240 VAC, 25 W with RUN output), CJ1W-PD022 (24 VDC, 19.6 W) or CJ1W-PD025 (24 VDC, 25 W).
