z CJ1W-OC201 Contact Output Unit (Independent Relays, 8 Points)
*1 Terminal numbers A0 to A8 and B0 to B8 are used in this manual, but they are not printed on the Unit.
Note Although 16 I/O bits (1 word) are allocated, only 8 of these can be used for external I/O. This Unit is also
treated as a 16-point I/O Unit in the I/O tables.
