2) Example of using TTL output drive and semiconductor contact input
※
Since the output side current uses a maximum 20mA output, it is necessary to
drive the external LED, photo coupler, and TTL semiconductor and use the
protection resistance after checking the driving current.
3) Example of Photocoupler Input / Output usage
※
Since the output side current uses a maximum 20mA output, it is necessary to
drive the external LED, photo coupler, and TTL semiconductor and use the
protection resistance after checking the driving current.
