following schemes can be chosen (Figure 5):
Figure 5: Two possible wiring configurations for the optoisolated output.
The first two configurations refers to non opto-isolated digital inputs, the other two to opto-isolated digital inputs.
The first configuration uses a pull-up resistor to obtain an “active-low” output signal; in
the second configuration the pull-down resistor allows the generation of a non-inverting
output signal.
The electrical specification of the optoisolator are listed in the following table:
