Note
The power consumption specifications in this document are maximum values for a
LabVIEW FPGA application compiled at 80 MHz. Your application power
requirements may be different. To calculate the power requirements of the
NI 9157/9159, add the power consumption/dissipation for the chassis and the I/O
modules you are using. Keep in mind that the resulting total power consumption is a
maximum value and that the NI 9157/9159 may require less power in your
application. For more information about the I/O module power requirements, refer to
the module operating instructions.
