Power Supply Specifications
The CPU module power supply specifications are explained below.
For the consumption current of extension modules, refer to

Page 37 PRODUCT LIST or manuals of each extension
module.
AC power supply type
*1 This item shows value when all 24 V DC service power supplies are used in the maximum configuration connectable to the CPU
module. (The current of the input circuit is included.)
*2 When I/O modules are connected, they consume current from the 24 V DC service power supply.
For details on the 24 V DC service power supply, refer to  Page 59 Limitation on Current Consumption.
*3 The value in [] is capacity of 24 V DC service power supply in the case where operating ambient temperature is lower than 0

.
The following shows the power failure detection time of the AC power supply type.
Item Specifications
Rated voltage 100 to 240 V AC
Allowable supply voltage range 85 to 264 V AC
Frequency rating 50/60 Hz
Allowable instantaneous power failure time Operation can be continued upon occurrence of instantaneous power failure for 10 ms or less.
When the supply voltage is 200 V AC, the time can be change to 10 to 100 ms by editing the user program.
