Isolated Outputs
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.
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.
