Unit Current Consumption And External Power Supply Capacity; External Power Supply Capacity When Expansion I/O Units Or Expansion Units Are Connected - Omron CP1E-E14SDR-A User Manual

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
CP1E.
2-4-1 External Power Supply Capacity When Expansion I/O Units or
Expansion Units are Connected
Power of 24 VDC can be supplied to external devices from E30/40/60(S), N30/40/60(S ) or NA20
CPU Units.
Calculate the usable capacity of external power supply according to the following example.
