Table 3-3 Voltage Range of Opto-Isolated Input
Electrical Level Input Type
Voltage Range
High electrical level input
10 V to 30 V
Low electrical level input
0 V to 2 V
The voltage range of low electrical level Input is set to 0 V to 2 V due to the voltage fluctuation of 0
V voltage under industrial application.
The vision box adopts NPN opto-isolated input, so different connection modes need to be adopted
according to the electrical features of different connected devices when they send signal.
