hHi,
I am a real beginner with the PiFace. I have a glue about Software, but not about Hardware so far. I wanted to connect via PIFACE the digital Output contacts of a industrial light sensor (12 V DC ) to the PIFACE. Has anyone experience how to do this? Thanks upfront for the Support.

Hi KR,
You should be able to use the open collector output on terminal 4 connected like this...
The PiFace input has the option of switching in a pull-up resistor - this option should be used since the open collector acts like a switch to ground and the resistor is needed to pull the input high when the switch is open.
