National Instruments NI sbRIO-960x ユーザーズマニュアル

© National Instruments Corporation

The sbRIO device requires a power supply connected to J3. The supply 
voltage and current must meet the specifications in the 

 section of this document, but the actual power requirement 

depends on how the device is physically configured, programmed, and 
used. To determine the power requirement of your application, you must 
measure the power consumption during execution, and add 20% to your 
estimates to account for transient and startup conditions.

Select a high-quality power supply with less than 20 mV ripple. The sbRIO device 

has some internal power-supply filtering on the positive side, but a low-quality power 
supply can inject noise into the ground path, which is unfiltered.

Four elements of the sbRIO device can require power: sbRIO internal 
operation; 3.3 V DIO; 5 V output; and board-only C Series modules 
installed on the device. Refer to the 

 section for 

formulas and examples for calculating power requirements for different 
configurations and application types.

Complete the following steps to connect a power supply to the device.

1.

Remove the MINI-COMBICON plug from connector J3 of the 
sbRIO-960x. Refer to Figure 4 for the location of J3.

2.

Connect the positive lead of the power supply to the V terminal of 
the MINI-COMBICON plug.

3.

Connect the negative lead of the power supply to the C terminal of 
the MINI-COMBICON plug.

4.

Re-install the MINI-COMBICON connector in connector J3.

When you apply power to the sbRIO-960x, the device runs a power-on self 
test (POST). During the POST, the Power and Status LEDs turn on. The 
Status LED turns off, indicating that the POST is complete. If the LEDs do 
not behave in this way when the system powers on, refer to the 

 section.

You can configure the device to launch an embedded stand-alone 
LabVIEW RT application each time it is booted. Refer to the Running a 
Stand-Alone Real-Time Application (RT Module) topic of the LabVIEW 
Help for more information.
