11.9 I3 series camera’s I/ O electrical properties
11.9.1 I3 series camera’s opto - isolated input circuit (line0)
In the camera I/O control, opto - isolated input circuit is shown in Figure 11 - 32.
Figure 11 - 32
Opto - isolated input circuit
Logic 0 input level: 0~1.4VDC (OPTO_IN pin)
Logic 1 input level: 2.2~24VDC (OPTO_IN pin)
Maximum input current: 30mA
The input level is between 1.4V and 2.2V, the circuit action state is uncertain, please avoid the input voltage working
in this range.
