Unit Current Consumption And External Power Supply Capacity; External Power Supply Capacity When Expansion I/O Units Or Expansion Units Are Connected - Omron SYSMAC CP Series User Manual

2 Basic System Configuration and Devices
2-4 Unit Current Consumption and
External Power Supply Capacity
This section describes the current consumption and external power supply capacity of units used by the
CP2E.
2-4-1 External Power Supply Capacity When Expansion I/O Units or
Expansion Units are Connected
When connecting Expansion Units and Expansion I/O Units to an E30/40/60, S30/40/60 or N30/40/60
CPU Unit, or when using the external power supply, ensure the power supply capacity is satisfied as the
following calculation examples.
