You can connect ground-referenced or floating signal sources to
the NI 9225. Connect the positive signal of the signal source to the
AI+ terminal, and connect the negative signal of the signal source
to the AI- terminal. If you make a ground-referenced connection
between the signal source and the NI 9225, make sure the voltage
on the AI+ and AI- connections are in the channel-to-earth safety
voltage range to ensure proper operation of the NI 9225. Refer to
the
Specifications
section for more information about operating
voltages and overvoltage protection.
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 9225.
