National Instruments NI 9481 - Manual (Page 9)

© National Instruments Corp. 9 NI 9481 Operating Instructions and Specifications
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 NI 9932 backshell
kit to protect the connections. Refer to Figure 4 for an illustration
of using ferrules. Refer to Figure 1 for an illustration of the
NI 9932 connector backshell.
