NI 9425 Connection Guidelines
•
Make sure that devices you connect to the NI 9425 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 9425 with spring terminal.
•
For the NI 9425 with spring terminal, push the wire into the
terminal when using a solid wire or a stranded wire with a
ferrule.
•
For the NI 9425 with spring terminal, open the terminal by
pressing the push button when using stranded wire without a
ferrule.
•
For CAT II measurements, you must use a power supply with
isolated DC outputs if you are using an external power
supply.
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 9425 with spring terminal.
