Powering the Module
The CompactRIO backplane male high density DSUB 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 functions. The CompactRIO 5 V source is active whenever the
CompactRIO or R Series Expansion Chassis is properly powered. You can power the NI 9760
only at the HD15 connector by plugging it into a CompactRIO or R Series Expansion Chassis.
Do not connect the HD15 connector to any other device.
If the 5V OUT lines or internal pull-up resistors are to be used for Hall-effect sensors, then the
external DB-37 connector pins labeled 5-30V IN (19) and GND (36) must be connected to an
external supply of 5V to 30V. The module is reverse battery protected to -30V. The NI 9760
external power ground and CompactRIO backplane power ground are isolated and have no
internal connection.
