Omron Series Selection Matrix

Decision Criteria

Use this decision framework to narrow down your selection:

1. I/O Count: Count your discrete and analog I/O points, add 20% for future expansion. CP series handles up to 320, NX up to 1,024, NJ unlimited.

2. Speed Requirements: For applications exceeding 60 cycles/minute, go with NX series or higher for native EtherCAT performance.

3. Motion Control: Need more than 2 servo axes? NJ series is your minimum. The integrated motion programming in Sysmac saves significant commissioning time.

4. Communication Needs: Already have an Allen-Bradley plant? Consider NJ's Ethernet/IP capability. Building greenfield in Asia? Native EtherCAT is your best bet.
