Wiring precautions
■No-voltage contact
Use input devices appropriate for low electric current.
When no-voltage contacts for large current (switches) are used, contact failure may occur.
■Input device with built-in series diode
The voltage drop of the series diode should be the following value or less.
Also note that the input current is over the input-sensing level while the switches are on.
