Basically, the function of a PLC is to
A) amplify various weak signal sources.
B) control a high-voltage output with a low-voltage input.
C) control the speed of motors.
D) make logical decisions and control outputs based on them.
Logical Decisions
The process of making choices based on logical conditions within programming or digital circuits.
Weak Signal Sources
Sources that generate signals with low amplitude or power, often requiring amplification or processing to be useful in applications.
- Understand the purpose and operation of a Programmable Logic Controller (PLC) in industrial automation systems.
- Comprehend the basic principles behind logic control and the mechanism by which PLCs perform logical operations.

Final Answer :
D
Explanation :
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.
