The following statement that does not apply to the optical isolator circuit used in I/O modules is that it
A)separates high-voltage and low-voltage circuits.
B)rectifies AC signals.
C)prevents damage caused by line voltage transients.
D)reduces the effect of electrical noise.

Question

Quizplus · Accepted Answer

Optical isolator circuits do not rectify AC signals. They use an optocoupler to transmit signals using light between two isolated circuits, providing electrical isolation to protect against voltage transients and electrical noise.
