Product Overview

The Omron CJ2M-CPU32 is the second step in the CJ2M CPU3x 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 10K steps plus 20K steps of function-block memory. Data memory is 64K words, split as 32K words DM plus 32K words EM in one bank. The CPU addresses up to 2560 local I/O across 40 mountable units and three expansion racks. Basic LD instruction execution is 0.04 microseconds. Built-in ports are EtherNet/IP and USB, plus an option board slot for CP1W-CIF01 (RS-232C) or CP1W-CIF11 / CP1W-CIF12-V1 (RS-422A/485).

Current draw is 5 V at 0.7 A. The unit is 90 x 62 x 84.5 mm and weighs 190 g. Programming runs in CX-Programmer. For the same 10K steps without EtherNet/IP, pick the CJ2M-CPU12. For more program, pick the CJ2M-CPU33 (20K steps) or CJ2M-CPU34 (30K steps). Add a CJ2M-MD211 for high-speed counter and pulse outputs.

Key Features

  • CJ2M CPU3x with 10K-step program plus 20K-step function-block memory
  • 64K-word data memory (DM 32K + EM 32K x 1 bank), 0.04 us LD instruction execution
  • Built-in EtherNet/IP and USB ports; option board slot for CP1W-CIF01 / CIF11 / CIF12-V1
  • 2560 I/O points across 40 units and 3 expansion racks, 5 V 0.7 A, 90 x 62 x 84.5 mm, 190 g
  • SKU: CJ2M-CPU32
  • Series: Omron CJ2M-series CPU Unit (CPU3x line, built-in EtherNet/IP)
  • I/O: 2560 points

Best-Fit Applications

  • Mid-size packaging line where the program grew past 5K and the cabinet needs EtherNet/IP for the new HMI
  • Spare CPU drop-in for a CJ2M-CPU31 cell where the original 5K program has filled and the slot is open for a CP1W-CIF11
  • Material handling cell with a CJ1W-PA202 power supply, several CJ1W-ID211 input units, and a CJ1W-OD212 output unit on the rack

Buying Checklist

  • Pick the CJ2M-CPU32 for the second step in the CJ2M CPU3x line with 10K steps of program and built-in EtherNet/IP.
  • Pick the CJ2M-CPU31 instead when 5K steps is enough and the rest of the spec is the same.
  • Pick the CJ2M-CPU34 instead when 30K steps of program is needed and the rest of the spec is the same.

FAQ for CJ2M-CPU32

What is the difference between CJ2M-CPU32 and CJ2M-CPU12?
Both have 10K steps of program. The CPU32 is on the CPU3x line with built-in EtherNet/IP and an option board slot. The CPU12 is on the CPU1x line with RS-232C + USB only and no option board slot.
How much program memory does the CJ2M-CPU32 have?
10K steps of program plus 20K steps of function-block memory for a total of 30K steps. The data memory side is 64K words.
Can the CJ2M-CPU32 replace a CJ1M CPU?
Yes. CX-Programmer imports the CJ1M project and the CJ2M CPU runs it with the same I/O addresses. I/O wiring does not need to change.
