3.4. Analog and Digital Inputs and Outputs
The module of analog and digital inputs and outputs (ADIO) is designed for :
• creating 20 mA current loops
• switching loads supplied with DC and AC current
• scanning digital signals
Each functional group of terminals is galvanically separated from the rest of the device as shown on
the internal layout diagram for the ADIO module on the image below:
