The Analog Input Module takes an analog signal from a hardware port, scales it and makes the scaled result available in its output register, allowing you to measure and store analog information
What does analogue input mean?
Analog input is a continuous input from the field to the PLC. Unlike digital signals, input levels change continuously (there are no high and low levels). It can vary depending on the field conditions. The commonly used analogue signals are 4-20mA signal or 0-10Vdc Signal.
What is an example of an analog input?
Analog Input - an overview | ScienceDirect Topics The analogue inputs are used in control systems with input sensors that produce a voltage, current or resistance change in response to an environmental variation or system measurement. For example, in the LPC board, a pot is connected to RA0, which is designated AN0 when used as an analogue input.
