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 Specifications for maximum continuous output current, short-circuit behavior, and short-circuit trip time specifications.
