Select Power Supplies

Select the power supplies for your nodes and the network aggregation subsystem. Each CompactDAQ chassis and Ethernet switch in your system needs its own DC power connection.

Instead of using the dedicated power supply that ships with these components, you can consolidate AC power conversion into larger power supplies that distribute their DC outputs to multiple components in the system.

Component Power Requirements

Refer to the following table to for the power requirements for the CompactDAQ chassis and Ethernet switch.

Table 2. Power Requirements
Model Power Requirements
cDAQ-9189 16 W, 9 V to 30 V
cRIO-9805 5 W, 9 V to 30 V
Note The power requirement for the cDAQ-9189 includes maximum 1 W power load per slot across rated temperature. Quarter-bridge strain gauge modules can draw close to 1 W depending on the use case. Refer to documentation for each component to create more sophisticated power budgets.

Power Supply Options

Refer to the following table to determine the best power supply option for your specific system design.

Table 3. Supported Power Supplies
Model Description
PS-14 24 VDC, 3.3 A, 80 W DIN-Mountable Industrial Power Supply
PS-15 24 VDC to 28 VDC, 5 A, 120 W, DIN-Mountable Industrial Power Supply
PS-16 24 VDC to 28 VDC, 10 A, 240 W, DIN-Mountable Industrial Power Supply
Note For example, a single PS-15 can comfortably power six fully loaded CompactDAQ chassis and one Ethernet switch, and the PS-16 can comfortably power 13 fully loaded CompactDAQ chassis and three Ethernet switches.
