 ### Input/Output Channels
 
-The Arduino Opta® Analog Expansion features 8 channels that can be configured as inputs or outputs. When the channels are configured as inputs they can be used as digital ones with a 0-24 V range, or analog being able to measure voltage from 0 to 10 V, measure current from 0 to 25 mA or temperature leveraging the RTD mode. 
+The Arduino Opta® Analog Expansion features 8 channels that can be configured as inputs or outputs. When the channels are configured as inputs they can be used as digital ones with a 0-24/0-10 V range, or analog being able to measure voltage from 0 to 10 V, measure current from 0 to 25 mA or temperature leveraging the RTD mode. 
 
 The channels **I1** and **I2** can be used for connecting 3-Wires RTDs. Every channel can be used also as an output, be aware that using more than two channels as an output simultaneously may overheat the device. This will depend on the ambient temperature and channel load. We have tested setting all eight channels as outputs at 25 °C outputting more than 24 mA at 10 V each without problem.
