Table 1.
Overcurrent Channel Protection Behavior
Amount of Current
through the DO Terminal
or Pin
Channel Behavior
Greater than 13 A
The channel trips and goes into an
overcurrent state, in which the channel
turns off and the module is not damaged.
Between 6 A and 13 A
The state of the channel is indeterminate
and depends on factors such as the current
level, temperature, and power supply.
Higher inrush currents that
exist for less than the trip
time
The circuit protection does not trip.
Note
Refer to the
NI 9475 Datasheet
at
ni.com/
manuals
for maximum continous output current, short-
circuit behavior, and short-circuit trip time
specifications and information about conditions that
may damage the module.
