National Instruments NI 9481 Wiring for High-Vibration Applications

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 9481.

When the channel is turned on, the terminal connected to the load

drives current or applies voltage to the load. When the channel is

off, the terminal does not drive current or apply voltage to the load.

Wiring for High-Vibration Applications

If an application is subject to high vibration, National Instruments

recommends that you either use ferrules to terminate wires to the

detachable screw-terminal connector or use the NI9932 backshell

kit to protect the connections. Refer to Figure4 for an illustration

of using ferrules. Refer to Figure1 for an illustration of the

NI9932 connector backshell.
