Link Terminals
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.

Note: Only normal I/O delay time (typically 19.2 ms) is available.
Meaning of "A" and "B"
A: Combinations with one 32-point model connected to two 16-point models.
32 points
B: One-to-one combinations of models with the same number of input or output points.
32 points
Note: 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.
