Hi,
I am a newbie to electronics circuity and would like to seek the forum's opinion.
In my current project, we're required to connect existing 8 IR receivers to 8 digital I/O pins on a motherboard. The motherboard I/O pins can be set as input pins, with 0V and 5V as the digital logic signal.
The existing IR receivers are Pepperl Fuchs LA31. The motherboard is Advantech AIMB N270
What is the proper way to connect the IR sensor receivers to the digital I/O pins? My initial queries are (sorry, they're very newbie questions):
1) The datasheet for the IR receiver says operating voltage of 12V ... 24V DC. Is this the signal output voltage?
2) Will connecting the IR sensor receiver signal output to the motherboard digital I/O pin cause the motherboard to fry?
3) Do I need to have a power regulator or step down to convert 12V to 5V?
4) Is there any power regulator that can take in 8 12V inputs and convert it to 8 5V outputs? Those that I know are only 1 input and 1 output (like LM7805), and therefore would require to have 8 of those
