 ====== Analog outputs ====== ====== 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.
  
 +<WRAP center round important 60%>
 +The AOs are only for signalling and not for powering devices. Sourcing more than 20mA will damage the output.

 +===== Analog outputs on Neuron and Axon =====
 +The functionality of AOs on Neuron and Axon is different on Group 1 and Group 2/3 and Neuron extensions. ​
 +
 +On Group 1, the analog output is capable of:
 +  * sourcing 0-10V DC
 +  * sourcing 0-20mA DC
 +  * and [[analog-inputs-hidden#​measuring_resistance|measuring resistance]] up to 2kOhm by a 2-wire method
 +
 +The analog outputs on Group 2 and 3 and the Neuron extensions are capable of:
 +  * sourcing 0-10V DC
 +
 +Changing between modes depends on the software you are using, please follow the relevant tutorial. ​

 +===== Analog output on Unipi 1.1 =====
 +The UniPi 1.1 has one analog output only capable of sourcing voltage in a range of 0-10V DC.
 +
 +====Usage of the UniPi 1.1's analog output====
 +
 +Analogue output on the UniPi 1.1 functions as a voltage regulator, requiring a voltage (connected to the AOV) and a ground (connected to the AOG). 
 +
 +Upon connecting the voltage, please check if the output voltage is set properly using the onboard trimmer. If not, the output voltage will not correspond with the required value.
 +
 +For the output voltage setting, we recommend the following steps
 +  - Connect a voltage source and ground
 +  - Set the required output voltage through a control software of your choice, or by using the Pulse-Width Modulation (PWM) firmware function
 +  - adjust the output voltage using the onboard trimmer and match it with the required voltage

 +An example of a 12V voltage connected to the AOV. The ground is connected to the AOG. The AOV then serves as a connector generating a positive voltage from the analogue input, which is routed to the AI1+. Thanks to this connection the user can read analog output value directly from the analog input. ​
