Connecting Lighting and External Devices
You can wire an isolated input to both sourcing and sinking output devices. Refer to Figures 4-4
and 4-5
for wiring examples by output type. Refer to Appendix A,
, for current
requirements.
Isolated inputs are not compatible with 5 V logic.
Figure 4-4.

Connecting External Sinking Output Sensors to Isolated Inputs
Isolated Outputs
Caution
The isolated inputs and outputs on the smart camera provide an easy
means for preventing ground loops that could degrade signal integrity. The isolation
on the smart camera is
not
safety isolation.
Caution
Do
not
power the load connected to the isolated outputs with any external
power supply greater than 30 VDC. Voltages greater than 30 VDC may damage the
NI Smart Camera.
