NI-9209 Connection Guidelines

 Make sure that devices you connect to the NI-9209 are compatible with the

module specifications.

 You must use 2-wire ferrules to create a secure connection when connecting

more than one wire to a single terminal on the NI-9209 with spring terminal.

 Push the wire into the terminal when using a solid wire or a stranded wire

with a ferrule.

 Open the terminal by pressing the push button when using stranded wire

without a ferrule.

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-9209 with spring terminal.

Overvoltage Protection

The NI-9209 provides overvoltage protection for each channel.

Note

 Refer to the NI-9209 Specifications on 

ni.com/manuals

 for more

information about overvoltage protection.
