Wiring the NI USB-9264 Device

The NI USB-9264 has a 36-terminal detachable spring-terminal connector
that provides connections for 16 analog output channels.

Caution

A high voltage screw terminal backshell must be installed when using hazardous

voltages (>42.4 V

pk

, 60 VDC).

Figure 7.

NI USB-9264 Terminal Assignments

Each channel of the NI USB-9264 has a terminal to which you can connect
the positive lead of a load. Each channel also has a common terminal,
COM, and there are four additional COM terminals at the bottom of the
connector. All of the COM terminals are internally connected to the
isolated ground reference of the module. When connecting a load to the
NI USB-9264, connect the positive lead of the load to the AO terminal, and
the ground of the load to a COM terminal. Refer to Figure 8 for an
illustration of connecting a load to the NI USB-9264.
