Product Overview

The Omron CJ2M-CPU15 is the top unit in the CJ2M CPU1x lineup, 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 60K steps and data memory is 160K words, split as 32K DM plus 32K words EM across four banks. The CPU addresses up to 2560 local I/O points across 40 mountable units and three expansion racks. Basic LD instruction execution is 0.04 microseconds. Built-in ports are RS-232C and USB only.

Current draw is 5 V at 0.5 A. The unit is 90 x 31 x 84.5 mm and weighs 130 g. Programming runs in CX-Programmer under the CX-One suite. For the same 60K-step capacity with built-in EtherNet/IP, pick the CJ2M-CPU35. For a smaller program size, pick the CJ2M-CPU12. Pair with a CJ2M-MD211 pulse I/O module when high-speed counters are needed.

Key Features

  • CJ2M CPU1x with 60K-step program and 160K-word data memory (DM 32K + EM 32K x 4)
  • 0.04 us LD instruction execution, 2560 local I/O points across 40 units and 3 expansion racks
  • Built-in RS-232C serial and USB ports; no EtherNet/IP and no option board slot
  • Programmed in CX-Programmer; 5 V 0.5 A current draw, 90 x 31 x 84.5 mm, 130 g
  • SKU: CJ2M-CPU15
  • Series: Omron CJ2M-series CPU Unit (CPU1x line)
  • I/O: 2560 points

Best-Fit Applications

  • Mid-size packaging line where a CJ2M-CPU12 already runs and the program is hitting the 5K-step ceiling
  • Spare CPU drop-in for a CJ2M rack where the existing program memory is full and the field bus is RS-232C only
  • Machine cell with a CJ1W-PA202 power supply and a CJ1W-II101 expansion interface on the left side of the rack

Buying Checklist

  • Pick the CJ2M-CPU15 for the largest CPU1x program capacity (60K steps) on the CJ2M platform.
  • Pick the CJ2M-CPU35 instead when the cabinet needs built-in EtherNet/IP or the option board slot for serial comms.
  • Pick the CJ2M-CPU12 instead when the program fits under 5K steps and the spare slot for an option board is not needed.

FAQ for CJ2M-CPU15

What is the difference between CJ2M-CPU15 and CJ2M-CPU35?
Both have 60K steps of program memory. The CPU15 is on the CPU1x line with RS-232C + USB only and no option board slot. The CPU35 is on the CPU3x line with built-in EtherNet/IP and an option board slot for CP1W-CIF01 / CIF11 / CIF12-V1.
How much current does the CJ2M-CPU15 draw?
0.5 A at 5 VDC from the rack power supply. Add 0.15 A when using an NT-AL001 RS-232C/RS-422A adapter or 0.04 A when using a CJ1W-CIF11 RS-422A adapter.
Which power supply pairs with the CJ2M-CPU15?
A CJ1W-PA202 (100-240 VAC, 14 W) or CJ1W-PD022 (24 VDC, 19.6 W). For 25 W output with a RUN relay, pick the CJ1W-PA205R.
