Key product information and technical features.
The NI-9229 provides general-purpose differential voltage acquisition. Its isolated, floating input architecture helps reduce measurement errors associated with ground loops.
NI offers multiple NI-9229 connector variants. The supplied catalog references part number 780180-01 but describes screw terminals; NI identifies 780180-01 as the BNC version. Confirm the module label and front connectors before selecting wiring or applying variant-specific isolation limits.

Product-specific answers based on available technical information.
Yes. It supports simultaneous acquisition at up to 50 kS/s per channel with 24-bit resolution.
The supplied information conflicts. NI identifies 780180-01 as the BNC version, while the legacy description specifies screw terminals. The exact variant needs confirmation from the module label and connectors.
No. Measurement range and isolation limits are separate specifications. Consult the datasheet safety section for the identified connector variant.
