I am putting together a low power data acquisition and control system. For that purpose I am using a desktop pc as a real-time target. As mentioned in the subject of the thread, I am using the DAQ cards PCI-6225 and PCI-6704.
As the system is very low power, I only have limited current available from the 12V rail on my ATX power supply – more specifically 400mA. This should be just enough for the motherboard, and my concern is therefore whether or not the DAQ-cards draw any current from the 12V rail.
