Slit Type Optoisolator

H21A1-DAQ board (Data acquisition board) wiring diagram. It is possible to connect in 2 different ways.
The first connection is made with a 5 V supply.

*** In addition, the LED DAQ must be connected to the card. The link is as follows;
Led + to DIO7
Led - should come to GND.
The connection method is the same for the following structure.

If the power supply is not desired, it is also possible to connect as follows.
