Need Help Sizing Your Power Supply?
Calculate total system power requirements based on controller and I/O module consumption. Follow the 3-step sizing workflow.
Power Supply Sizing Calculator
Step 1: Controller Base Power
Check your controller datasheet for base power consumption (varies by model and configuration)
Step 2: Sum Module Power
Add up the mA ratings of all I/O modules you plan to install. Example: 50mA + 100mA + 110mA + 100mA = 360mA
Step 3: Calculate Total + Safety Margin
Add controller power + module power, then add 20-30% safety margin for future expansion
Step 4: Select Appropriate Power Supply
Choose power supply that exceeds your total calculated requirement. CPS-PWD-90AW24-01 (91.2W) recommended for configurable systems
