This device is responsible for converting analog signals from external devices to digital signals that can be processed by a computer.
What is the difference between analog and digital IO?
Analog signals can be affected by noise and interference, so they need extra protection like shielding and filtering. Digital signals are stronger in noisy places, so digital I/O modules are better in areas with high electromagnetic interference (EMI). Cost: Look at the costs of each type of I/O module.
