Can you help me see if there is anything to pay attention to when converting the 24V IO port to 3.3V IO port? Or is there a better solution?

The measured waveform is like this, and it feels no problem when you look at it.

Each transistor has a turn-on time and a turn-off time. If the signal jumps much slower than the switch time after 24 volts, there is no problem.

The logic is the inverse logic, if you need the same logic, you can use the PNP tube
