Need guidence to improve latency and speed

Thanks. I've put in the order for this card. Expected the 22th of may

From what I’ve researched, the Mesa 7i76EU seems like the best option. Here’s why:

It has 32 opto-isolated inputs which should work well with the 24V NPN homing sensors

The 7I76EU inputs work directly with PNP sensors (or switches) NPN sensors will require pull-up resistors.

The sensors might need a pull-down resistor to give clean logic signals when connected to 24V. I already solderd a pc to convert the 30V signal back to a 5V system with opto's

7I76EU isolated inputs do not require any additional components with PNP sensors or switches.
Note that 5V signals will not work when you have 24V field power as the input threshold will be about
12V in this case.
