What this unit does in a CJ1 rack
The Omron CJ1W-SPU01-V2-301 is a Data Storage/Processing Unit that mounts as a PLC Expansion Module in a CJ1-series programmable-logic-controller rack. It handles data storage and processing tasks offloaded from the CPU, freeing scan-cycle bandwidth for core logic.
Physical fit — panel and rack
No additional mounting hardware beyond the DIN-rail latch and the backplane connector is required.
