Understanding Analog Inputs in PLC Systems: Bridging the Gap Between Digital and Analog Signals

Analog inputs are the lifeline of modern automation systems, acting as the crucial link between physical processes and digital controllers like PLCs (Programmable Logic Controllers). Grasping the concept of analog inputs and how they differ from digital inputs is essential for anyone involved in industrial automation. This article will delve into what analog inputs are, how they function within PLC systems, and why understanding the differences between analog and digital signals is vital.
