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 Section 4.4.1 to view the exact location of each I/O.
The electrical equivalent circuits of these I/O are shown in following figure:
INPUT
0V ≤ V
IN
≤ 0.7V → Logic ‘0’
0.9V ≤ V
IN
≤ 30V → Logic ‘1’
OUTPUT
Logic ‘0’ → V
OUT
= 1V (max)
Logic ‘1’ → V
OUT
= HiZ
To know how to read and write these lines please read the MTX-IoT Family Software Manual
