=== Sorties à collecteur ouvert ===
The 8 outputs on PiFaceTM Digital 2 are open-collector outputs, which can be used to control devices such as lights, motors or relays (which may require different voltages).
Because the outputs are open-collector, they do not output any voltage, instead they enable or disable current to flow to ground.
This gives greater flexibility as the outputs can operate at different voltages (since the PiFaceTM Digital 2 doesn’t supply the voltage).
{{ambox-stop|text=Note: If the outputs are to be used for devices that operate at greater than 5V then jumpers must be set appropriately to avoid damage. For example disconnect jumpers JP4, JP5, JP6 and JP7.}}
