Sourcing Digital Input Configuration
Port 0 of the sourcing digital input is powered at +24 V through the sbRIO-9687 interface
board. This power is available at the DI connector on pins 9 and 27. The +24 V can be used to
power external circuits or port 1.
Port 1 is not powered from sbRIO-9687 interface board; it should be powered externally at a
voltage that matches the voltage levels of the application. Power for port 1 is connected at pins
18 and 36 of J12 connector.
Port 0 DI lines are used on the sbRIO-9687 interface board. For details, refer to Halt Signals
on page 36 and GPIO Signals on page 37. If Port 0 DI lines are not used for the application,
they can be disconnected from onboard functionality by depopulating the corresponding
resistor.
Note If port 0 sinking DI lines are used outside the sbRIO-9687, they should be
disconnected from onboard functionality.
The following table provides information about the onboard function and corresponding
resistor for sourcing DI signals.
