Calculating the Power Budget
Managing Your Power Resource
When you determine the types and quantities of I/O modules you will be using in the DL205
system, it is important to remember there is a limited amount of power available from the
power supply. We have provided a chart to help you easily see the amount of power available
with each base. The following chart will help you calculate the amount of power you need
with your I/O selections. At the end of this section is an example of power budgeting and a
worksheet for your own calculations.
If the I/O you choose exceeds the maximum power available from the power supply, you may
need to use local expansion bases or remote I/O bases.
WARNING: It is extremely important to calculate the power budget. If you exceed the power budget,
the system may operate in an unpredictable manner, which may result in a risk of personal injury or
equipment damage.
CPU Power Specifications
The following chart shows the amount of current available for the two voltages supplied from
the DL205 base. Use these currents when calculating the power budget for your system. The
Auxiliary 24V Power Source mentioned in the table is a connection at the base terminal strip
allowing you to connect to devices or DL205 modules that require 24VDC.
Module Power Requirements
Use the power requirements shown on the next page to calculate the power budget for your
system. If an External 24VDC power supply is required, the external 24VDC from the base
power supply may be used as long as the power budget is not exceeded.
