The 0.1 µs LD execution holds takt time for a compact cell — constant cycle time can be set from 1 to 32 ms for deterministic scans. Data area memory is 32 K words. ## I/O and Physical Mounting Supports up to 320 I/O points across a maximum of 10 expansion units. Mounts on DIN rail only — screw mounting is not possible. Dimensions are 31 x 73 x 95 mm.","metaTitle":"OMRON CJ1M-CPU12(4)-2 CPU Unit, 10 K Steps, EOL","metaDescription":"Obsolete CJ1M-CPU12(4)-2 CPU Unit by OMRON. 10 K step program, 320 I/O, 0.1 µs LD execution.
