more than 2,200 µF of bulk capacitance close to the NI 9470
module.
1. Connect the positive lead of the power supply to V
sup
.
2. Connect the negative lead of the power supply to COM.
I/O Protection
Each DO+ channel of the NI 9470 has short-circuit protection.
Each V
sup
terminal has reverse polarity protection.
Notice
Voltages greater than the supply voltage and
negative voltage conditions on DO+ can damage the
NI 9470.
Notice
The DO- terminal is not protected against
overvoltage conditions.
Note
Refer to the
NI 9470 Datasheet
on
for maximum continuous output current,
short-circuit behavior, and short-circuit trip time
specifications.
