Hardware
In addition to the listed analog and digital inputs, the NI 9752 provides sensor power and ground.
The cRIO chassis backplane directly provides sensor power. Ensure that sensors do not draw
more than a total of 100 mA.
NI recommends using the NI 9923 Connector Kit for connections to the NI 9752. The NI 9923
provides proper strain relief for NI 9752 connections. Visit

Powering the Module
The NI 9752 requires power from the CompactRIO backplane male high density D-SUB 15-pin
(HD15) connector, which mates with the female HD15 connector on the module. This power
source provides a regulated 5 V and ground to various digital logic and analog functions within
the NI 9752. The CompactRIO 5 V source is active whenever the CompactRIO or R Series
Expansion Chassis is properly powered. You can power the NI 9752 only at the HD15 connector
by plugging it into a CompactRIO or R Series Expansion Chassis.
