Analog inputs
Analog inputs (AI) are for measuring analog values such as voltage, current and resistance. These values are produced by sensors which indicate multiple states such as thermometers, tensometers, distance meters, luxmeters etc.
Analog inputs Neuron and Axon
The functionality of AIs on Neuron and Axon is different on Group 1 and Group 2/3 and on Neuron extensions.
On Group 1, the analog input is only capable of measuring DC voltage in a range of 0-10V and DC current in a range of 0-20mA.
On Group 2 and 3 and on the Neuron extensions, the analog input is capable of:
- measuring 0-10V DC
- measuring 0-2.5V DC with higher precision
- measuring of 0-20mA DC
- measuring of resistance 0-100kOhm via 2-wire method
- measuring of resistance 0-2kOhm via more precise 3-wire method

Analog inputs on Unipi 1.1
The UniPi 1.1 has two analog inputs and they are only capable of measuring voltage in a range of 0-10V DC.
