1. Output terminals to be used
If the high-speed output special adapter is connected, output numbers will be assigned in the same way as
the main unit as shown in the following table. Use the output terminals of one side (main unit side or high-
speed output special adapter side), and do not connect lines to the output terminals of the unused side.
The outputs of the high-speed output special adapter and the main will operate as follows.

• If an output number of the high-speed output special adapter is used (if an output of the high-speed output
special adapter is connected), do not use (connect) the corresponding output terminal of the main unit.
• If an output number of the main unit is used (if an output of the main unit is connected), do not use
(connect) the corresponding output terminal of the high-speed output special adapter.

The output frequency limit of the main unit transistor output is 100 kHz. When operating a load with a
pulse frequency exceeding 100 kHz, PLC failure may occur.
Furthermore, use of the PWM (FNC 58) is not recommended with the relay type main unit and the
high-speed adapters due to chattering of the relay contacts.
The PWM instruction does not support the triac output due to response delay of outputs.
