Choosing an Omron PLC: CP2E vs CJ vs NX I/O

Omron's controller range splits into three practical tiers. The CP2E compact PLC covers small machines that need built-in dual Ethernet at the lowest cost per I/O point. The CJ platform (CJ2H, CJ2M, CJ1W) is the modular mid-range: a CPU plus CJ1W I/O, communication and specialty units on one rack. NX-series I/O belongs to the Sysmac family (NX1P2, NJ, NX7 controllers) and is the right layer when you need EtherCAT motion or high-channel-count slices.

Lifecycle status matters as much as features here. CP1E is discontinued and CP1L/CP1H are being phased out — CP2E-N and CP2E-S are Omron's functional successors. CJ1W remains widely supported, and NX is the actively developed line. If you are maintaining an older machine, tell us the installed CPU and we will cross-reference the exact successor or a compatible spare.

This category also covers the supporting cast: DRT2 DeviceNet I/O, CK3M/CK3W axis and I/O units, and legacy C200HW/CS1W power and cabling. Every unit listed is genuine Omron stock — share your BOM and we confirm compatibility before you order.

Featured Product Guides

  • Use exact SKU matching for replacements, especially when terminal type and communication suffixes differ.
  • For controllers projects, sharing machine model, load profile, and installation environment helps us recommend the right variant faster.
  • Ask for quotation with quantity tiers to compare unit pricing and lead-time options in one response.
  • Most of these models are around 320 points — tell us your point count and we will confirm the exact variant.

Frequently Asked Questions

What replaces a discontinued Omron CP1E or CP1L?
The CP2E series is Omron's successor line for compact machine control: CP2E-N adds dual Ethernet, CP2E-S and CP2E-E cover simpler applications without it. I/O counts and expansion follow the CP1W ecosystem, so most small machines migrate with only wiring and program adjustments. Send us the old CPU part number and we will confirm the closest CP2E equivalent.
Should I choose CP2E or a CJ1W/CJ2H system?
Choose CP2E when the machine is small (up to 60 built-in I/O plus 3 expansion units) and cost matters — it has two Ethernet ports built in and no rack to configure. Choose CJ when you need more I/O, specialty CJ1W units (analog, motion, serial), or plan to grow. Choose NX I/O when the controller is a Sysmac CPU with EtherCAT motion.
Can I use NX I/O units on a CJ rack?
No. NX units require an NX-series CPU (NX1P2, NJ, NX7), an NX EtherCAT coupler (NX-ECC), or a communication adapter. CJ racks only accept CJ1W-series units. If you need modern I/O on a CJ system, the CJ1W-AD/DA analog and CJ1W serial/ network units are the compatible path.
Do you stock the expansion and communication units, not just CPUs?
Yes. This category includes CJ1W digital and analog I/O, CJ1W-EIP/ETN/SCU communication units, CP1W expansion I/O, power supplies and racks. Quote the complete configuration and we ship it as one matched set.
