Excitation Protection

The NI 9219 protects the excitation circuit from overcurrent and
overvoltage fault conditions. The NI 9219 automatically disables
the circuit in the event of a fault condition. Whenever possible,
channels automatically recover after the fault is removed.

Note

 

Refer to the device datasheet on 

ni.com/manuals

for more information about excitation protection.

Measurement Type Pinout

The following sections include pinouts for the NI 9219
measurement types.
