Piface Digital Outputs

Wed May 13, 2015 12:25 pm

Can I isolate my relays so I can have 10 outputs?
So I will have 8 separate open-collector outputs and 2 change over relays
currently out 0 switches both open-collector 0 and change over relay 0.
If possible what would my statement look like ??

I have .....etc
Output0 = 0

would the isolated relays be 8 and 9 ? can't seem to find any literature

No, the PiFace board only has 8 outputs maximum. The 2 relays are just in parallel with the first 2 outputs.

I think the documentation is pretty good. Start at Also check the element14 site at ... spberry-pi and the guide at ... tarted.pdf.
