16.4.3 Contact Input Wiring
CAUTION
1) Use a no-voltage contact (relay contact etc.) for external contacts.
2) Use a no-voltage contact which has ample switching capacity for the terminal's
OFF voltage (approx. 5V) and ON current (approx 1mA).
3) When using a transistor contact, the voltage at both terminals must be 2 V or
less when the contact is ON and the leakage current must be 100 µA or less
when it is OFF.
4) If there is a risk of external lightning surges, use a lightning arrester etc.
