Calculate System Power Consumption

The 1769 Compact I/O power supplies provide power to Compact
GuardLogix local and more banks. The provided power is measured in current
capacity.
Consider these points when you design your Compact GuardLogix 5370
controller system banks:
• 1769 Compact I/O power supplies have two maximum current capacity
requirements that affect how you design and configure one bank.
The following are the maximum current capacity requirements:
– Maximum current capacity for one bank
– Maximum current capacity for each side of the power supply
Current Capacity
for Side of Bank
• The maximum current capacity requirements vary by the power supply
that is used in the bank.
