I just want to make sure about how to implement this enter image description here

to an MCU's input pin, if the MCU is limited to 8mA sinking/source current. And 3.3V input voltage.


Supply is 4.55~24V, while output is Open collector to any low voltage, so you can pullup to 3.3V limited to 13mA. This does not use MCU current but rather Vdc only.

Thus you could choose 1K (3.3mA) or 10K (0.33mA) which is adequate.
