Power Connectors and Wiring
The FieldDAQ device has two 5-pin L-coded M12 power connectors, power IN and power
OUT. The power connectors provide one voltage line (V), one common line (C), chassis
ground, and two lines for optional auxiliary power, Aux1 and Aux2.
The following figure shows the power circuitry on the FieldDAQ device.

Basic Information
.
The FD-11613 has a maximum device power consumption of 4.9 W. Each FieldDAQ filters
and regulates the supplied power for its tasks.
When FieldDAQ devices are linked together through the power IN and power OUT
connectors, the total current consumption of the chain equals the sum of every linked
FieldDAQ device’s current consumption. The total current cannot exceed 10 A, and the total
supply load of the chain must be less than 300 W.
You can use the optional auxiliary power lines (Aux1 and Aux2) to draw power for
non-FieldDAQ devices in your network. 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.
