You can design circuit diagram for other devices according to the two diagrams above.
3.2.3 Opto-Isolated Output
The opto-isolated output of vision box adopts open collector and unidirectional output. When the
circuit is used for output, current from external power supply flows into opto-isolated output port,
then flows out. The current of every output pin cannot exceed 90 mA. Refer to the following table
for the voltage threshold of output channel.
Table 3-4 Voltage Range of Opto-Isolated Output
Electrical Level Output Type
Voltage Range
High electrical level output
5 V to 30 V
Low electrical level output
0 V to 1.1 V
The vision box adopts NPN opto-isolated output, so different connection modes need to be
adopted according to the electrical features of different connected devices when they send signal.
