1) Line Driver I/F
•
This is a good signal transmission method that is
less sensitive to noises. We recommend 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 correspond-
ing to the capacity of the VDC value.

SI Connecting to
se quence input signals
•
Connect to a contact of switch and relay, or a tran-
sistor 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 ap-
propriate level of primary current of the photo cou-
pler.
