C)control the speed of motors.
D)make logical decisions and control outputs based on them.

Question

Quizplus · Accepted Answer

PLC stands for Programmable Logic Controller, which means it is designed to make logical decisions based on input signals and control outputs accordingly. PLCs are commonly used in industrial and manufacturing processes to automate and control machinery and equipment. While they are capable of controlling the speed of motors and working with high-voltage outputs, their primary function is to make logical decisions and control outputs based on them. Amplifying weak signal sources is not within the scope of a PLC's function.
