NI-9263 Specifications

NI-9263 Nomenclature

In this article, the NI-9263 with screw terminal and NI-9263 with spring terminal are referred to inclusively as the NI-9263.

Definitions

Warranted specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

  • Typical specifications describe the performance met by a majority of models.
  • Nominal specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are Typical unless otherwise noted.

Conditions

Specifications are valid for the range -40 °C to 70 °C unless otherwise noted. All voltages are relative to COM unless otherwise noted.

Safety Voltages

Connect only voltages that are within the following limits:

Channel-to-channel

None

Channel-to-earth ground

Continuous

250 V RMS, Measurement Category II

Withstand

2,300 V RMS, verified by a 5 s dielectric withstand test

Measurement Category II

Caution Do not connect the product to signals or use for measurements within Measurement Categories III or IV.
Attention Ne pas connecter le produit à des signaux dans les catégories de mesure III ou IV et ne pas l'utiliser pour effectuer des mesures dans ces catégories.

Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.

Calibration

You can obtain the calibration certificate and information about calibration services for the NI-9263 at ni.com/calibration.

Calibration interval

1 year

1 When the module powers on, a glitch occurs for 20 μs peaking at -1.5 V.

2 The power-down voltage peaks at 1.8 V before exponentially discharging to 0 V in 100 μs. You can add a 10 kΩ load to reduce the peak voltage.

3 Range equals ±10.7 V

4 Uncalibrated accuracy refers to the accuracy achieved when acquiring in raw or unscaled modes where the calibration constants stored in the module are not applied to the data.
