・ Connect to a contact of switch and relay,
or a transistor of an open collector output.
・ Use a switch or relay for micro current so
that insufficient contact can be avoided.
・ Lower limit of the power supply (12 to
24V) should not be less than 11.4V in
order to secure the appropriate level of
primary current of the photo coupler.

① Line Driver I/F
・ This is a good signal transmission method
that is less sensitive to noises. We rec-
ommend you to use this to maintain the
reliability of signals.
② Open Collector I/F
・ This uses an external control power supply(VDC).
・ This requires a current-limiting resistor
corresponding to the capacity of the VDC
value.
