Connecting the cRIO-9068 to Power
The cRIO-9068 requires a 9 V to 30 V external power supply. The cRIO-9068 filters and
regulates the supplied power and provides power for the C Series modules. The cRIO-9068
has a primary power input, V1, and a secondary power input, V2.
The POWER LED on the cRIO-9068 indicates which power input is in use, as shown in the
following table.
Table 1. POWER LED Indicators
LED Color LED Pattern Indication
Green Solid The cRIO-9068 is powered from the V1 input.
