Five Types and 55 Models Can Be Combined Freely for a Variety of Applications to
Save Wiring Effort
Ordering Information
I/O Combinations
32-point models (screw terminal models), 16-point models (screw terminal models, modular models, and hybrid IC models), PLC connector
models (16-point models and 32-point models), I/O combination models (16-input/16-output models and 8-input/8-output models), 10-point
models (screw terminal models, modular models, and sensor I/O connector models), and Interface Units for PLCs (CQM1 and C200H/HS) are
available for a variety of applications.

With 32-point models, 16-point models, and PLC connector models, two I/O delay time settings are available: high-speed (typically
3 ms) and normal (typically 19.2 ms). Use the same settings for combined Terminals.

Note:
The 10-point model has a normal I/O delay time of 19.2 m (typical); 10-point models with short I/O delay time are not available.
The transmission signals of the 16-point PLC connector model are not compatible with those of the 10-point model. Therefore
16-point PLC connector models and 10-point models cannot be used in combination.
