Page 9: Sleep Mode
The overcurrent protection allows only a specified amount of current through the output channels to protect the NI 9403 from short circuits. If the NI 9403 goes into an overcurrent state, the module sets all the DIO channels to high impedance for approximately 280 milliseconds. -
