OSNK - Open collector outputs
Below is the detailed schematic of the open collector digital output, which is configured as current sourcing.
Schematic:
Notes:
The open collector output is current limited by the internal current limiting resistor. Use the following formula to understand the maximum current that can be sunk:
Vopto / 4700 = Iout
Vopto : the opto voltage input
Iout : the maximum current that will flow in Amps when the output is shorted to opto+V.
Actual current may be lower based on the external circuit connected.
Example wiring:

JBD-4EX-I26 general I/O pins configured as sinking and output.
