Contact input wiring
Either a semiconductive contact or a no-voltage contact can be used as the
contact input.
The contact input/output terminals are not available when a 2-contact output
model has been selected.

Pay close attention to voltage and polarity when wiring, because this is an
open collector output.

this is impossible
Note:
• Miswiring of polarity may cause damage to the equipment.
Recheck wiring position carefully.
Use an external power supply with voltage and capacity that
satisfy the specifications.
