4.4.4 Optoisolated I/O
The STD and DB15 models have two optoisolated inputs and two optoisolated outputs, located in the
DB15 HD expansion port. Please refer to
The electrical equivalent circuits of these I/O are shown in following figure:
0V ≤ V
0.9V ≤ V
To know how to read and write these lines please read the MTX-IoT Family Software Manual
