Analog Input Products
Analog input boards are useful for measuring variably changing conditions in the real world. When we want to measure these variably changing conditions, we need analog inputs to convert these changing real world conditions to changing electrical quantities. For example, monitoring the temperature inside a wood kiln, or the water pressure on the output of a pump, or the heart rate of a medical patient. In each of these cases, you can use one of our analog input devices to convert the electrical d...show more -
