Analog outputs

Analog outputs (AO) are for controlling multi-state devices through levels of DC voltage or current. Devices, which can be controlled in such way are for example multiposition valves, light dimmers, servos, linear actuators etc.

The AOs are only for signaling and not for powering devices. Sourcing more than 20mA will damage the output.

The functionality of AOs on Neuron and Axon is different on Group 1 and Group 2/3 and on Neuron extensions.

On Group 1, the analog output is capable of:

  • sourcing 0-10V DC
  • sourcing 0-20mA DC
  • and measuring resistance up to 2kOhm via 2-wire method

On Group 2 and 3 and on the Neuron extensions, the analog output is capable of:

  • sourcing 0-10V DC

Changing between modes depends on the software you are using, please follow the relevant tutorial.

Measuring resistance

The UniPi 1.1 has one analog output and it is only capable of sourcing voltage in a range of 0-10V DC. The device can be connected to the UniPi 1.1 this way
