Yes you can, each channel in the 4CH PRO is an isolated relay. So you are OK to power the device with 220V AC or even 12VDC (there are separate inputs for AC vs DC), then you can use any tension on each individual channel.
Thank you Mario. Same issue: 7 solenoid valves 24V + 1 lamp 240V. Please find attached my project. Is it correct?
