Overcurrent Fault
Overcurrent fault is a scenario when a digital output is sourcing or sinking a continuous output
current greater than 150 mA before the short-circuit protection is activated.
Caution
The number of digital output channels with overcurrent fault should not
be more than ten channels simultaneously.
Front I/O Overvoltage Protection
Digital input and output channels are protected against overvoltage which is outside of the
valid operating range at the front I/O connector up to ±100 V.
Note
Overvoltage protection is based on hiccup-mode protection using the
channel-disconnect switch with one second auto-retry time.
Fault Indicator
The short-circuit fault and front I/O overvoltage fault share one common fault indicator which
is stored in a register.
Note
Refer to the example LabVIEW VI to get more information about module
registers.
