Analog Inputs : 16-Channel Analog Input Module
Analog inputs are signals in which the primary variable of interest varies with time and is proportional to another time-varying quantity. An example of this is a voltage reading for a pressure sensor that varies proportionally to the changes in pressure seen by the sensor. An analog input module is an electrical component that takes analog inputs and distributes or processes those inputs based on the type of module. The number of channels defines the number of individual inputs, though each channel may not be a unique sensor or input device since each input device may have different channel requirements. For example, a 16-channel module may be able to read 16 one-channel sensors or 8 two-channel sensors.
