NI-9264 Getting Started

Connector Types

The NI-9264 has more than one connector type: NI-9264 with spring terminal and NI-9264 with DSUB. Unless the connector type is specified, NI-9264 refers to all connector types.

The NI-9264 with spring terminal is available in two types: push-in spring terminal and spring terminal. The push-in type spring terminal connector is black and orange. The spring terminal connector is black. NI-9264 with spring terminal refers to both types unless the two types are specified. Differences between the two types of spring terminal connectors are noted by the connector color.

NI-9264 Connection Guidelines

Make sure that devices you connect to the NI-9264 are compatible with the module specifications.

Connecting Wires to the NI-9264 with Spring Terminal (Black Connector)

What to Use

  • NI-9264 spring-terminal connector
  • 0.14 mm2 to 1.5 mm2 (26 AWG to 16 AWG) copper conductor wire with 10 mm (0.394 in.) of insulation stripped from the end
  • Flathead screwdriver with a 2.3 mm x 1.0 mm (0.09 in. x 0.04 in.) blade, included with the NI-9264

What to Do

Complete the following steps to connect wires to the spring-terminal connector.


1378

  1. Insert the screwdriver into a spring clamp activation slot to open the corresponding connector terminal.
  2. Press a wire into the open connector terminal.
  3. Remove the screwdriver from the activation slot to clamp the wire into place.

Connecting Wires to the NI-9264 with Push-in Style Spring Terminal (Black/Orange Connector)

What to Use

  • NI-9264 with push-in style spring terminal (black/orange connector)
  • 0.14 mm2 to 1.5 mm2 (26 AWG to 16 AWG) copper conductor wire with 10 mm (0.394 in.) of insulation stripped from the end
  • Ferrules (optional)

What to Do

Refer to the following table for how to insert a wire into a terminal depending on what type of wire you are using or if you are using a ferrule.
OptionDescription
When using a solid wire or stranded wire with a ferrule Push the wire into the terminal when using a solid wire or stranded wire with a ferrule
When using a stranded wire without a ferrule Press the push button and then push the wire into the terminal
Note You must use 2-wire ferrules to create a secure connection when connecting more than one wire to a single terminal.

High-Vibration Application Connections

If your application is subject to high vibration, NI recommends that you use the NI-9940 backshell kit to protect connections to the NI-9264 with spring terminal.

Conformal Coating

The NI-9264 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-9264 Safety, Environmental, and Regulatory Information, the NI-9264 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.
