for the subnet where you want it to be and physically move it to the other
subnet. Refer to the
Measurement & Automation Explorer Help
for more
information about configuring the device in Measurement & Automation
Explorer (MAX).
Powering the NI sbRIO Device
The NI 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.
Note
Select a high-quality power supply with less than 20 mV ripple. The NI 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 NI 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.
Refer to Figure 10 for an illustration of the power supply connections.
