 Analog inputs (AI) are for measuring analog values such as DC voltage, current and resistance. These values are produced by sensors which indicate multiple states such as thermometers,​ tensometers,​ distance meters, lux meters etc. Analog inputs (AI) are for measuring analog values such as DC voltage, current and resistance.
