Connecting an External Power Supply
You must connect an external power supply to the NI 9351. The
module is independent from the chassis and requires an external
power supply to operate.
Connect the positive lead of the power supply to the supply pin,
V
sup
, and the negative lead of the power supply to any common
pin, COM.
Caution
Do not remove or insert modules if the
external power supply connected to the V
sup
and COM
pins is powered on.
The NI 9351 has current sourcing outputs, meaning the DO pin is
driven to V
sup
when the channel is turned on.
