7

You can connect ground-referenced or floating current sources to
the NI 9227. Connect the positive side of the current source to the
AI+ terminal, and connect the negative side of the current source
to the AI- terminal. If you make a ground-referenced connection
between the current source and the NI 9227, 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 9227. Refer to
the

Specifications

section for more information about operating

voltages.

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 9227.
