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.

NI-9263 Block Diagram

Each channel has a digital-to-analog converter (DAC) that produces a voltage signal. Each channel also has overvoltage and short-circuit protection.

NI-9263 Pinout



Note You must use 2-wire ferrules to create a secure connection when connecting more than one wire to a single terminal on the NI-9263.
Table 1. Signal Descriptions
Signal Description
AO Analog output signal connection
COM Common reference connection to isolated ground
NC No connection

Connecting a Load

You can connect a load to each channel of the NI-9263.

When the NI-9263 powers on, the channels output the startup voltage. You can configure the startup voltage in software.

High-Vibration Application Connections

If your application is subject to high vibration, NI recommends that you follow these guidelines to protect connections to the NI-9263:
  • Use ferrules to terminate wires to the detachable connector.
  • Use the NI-9927 backshell kit with the NI-9263 with screw terminal or the NI-9981 backshell kit with the NI-9263 with spring terminal.

Conformal Coating

The NI-9263 is available with conformal coating for additional protection in corrosive and condensing environments, including environments with molds and dust.

In addition to the environmental specifications listed in the NI-9263 Safety, Environmental, and Regulatory Information, the NI-9263 with conformal coating meets the following specification for the device temperature range. To meet this specification, you must follow the appropriate setup requirements for condensing environments. Refer to Conformal Coating and NI RIO Products for more information about conformal coating and the setup requirements for condensing environments.

Operating humidity (IEC 60068-2-30 Test Db) 80 to 100% RH, condensing
