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.
Power of 24 VDC can be supplied to external devices from CPU Units with 30 or 40 I/O points.
Calculate the usable capacity of external power supply according to the following example.
