*1. Current consumptions include current for a Programming Console. Add 0.15 A per Adapter when using NT-AL001
RS-232C/RS-232A Adapters. Add 0.04 A per Adapter when using CJ1W-CIF11 RS-422A Adapters.
*2. Some of the specifications for the low-end CJ1M CPU Units (CJ1M-CPU11(-ETN)/21) are different from the
specifications for the other CJ1M CPU Units (CJ1M-CPU12(-ETN)/13(-ETN)/22/23), including the specifications for
overhead time, pulse start time, the number of subroutines and jumps, the number of scheduled interrupt tasks, and
the number of PWM outputs. For details, refer to the CJ Series Programmable Controllers Operation Manual
(Cat. No. 393) and the CJ Series Built-in I/O Operation Manual (Cat. No. 395).
*3. The connector for built-in I/O in the CJ1M-CPU21/22/23 is not included. Purchase one of the connectors or connector
cables in the following table separately.
