National Instruments FieldDAQ FD-11601 User Manual page 15

You can use the optional auxiliary power lines (Aux1 and Aux2) to draw power for
non-FieldDAQ devices in your network. The FieldDAQ device does not make use of
the auxiliary power itself. If you are connecting power through the auxiliary power
lines, ensure that the total combined current between V Input and Aux power lines
does not exceed 10 A.
Refer to the FD-11601 Specifications for information about the power connectors,
power requirements, and current limits of your FieldDAQ device.
Cap the power connectors when not in use.
