2  SPECIFICATIONS
2.2  Power Supply Specifications

■Expansion board, expansion adapter

For dielectric withstand voltage test and insulation resistance test of each product, refer to manuals of each product.

■Intelligent function module

For information concerning dielectric withstand voltage and insulation resistance of intelligent function modules, refer to  
manuals of each intelligent function module.

The CPU module power supply specifications are explained below.
For the consumption current of extension modules, refer to Page 31 PRODUCT LIST or manuals of each extension 
module.

*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.

For details on the service power supply, refer to Page 48 Limitation on Current Consumption.

Between terminal of expansion board and ground terminal

Not allowed

Not allowed

Since the expansion board and 
CPU module are not insulated, it 
is not allowed to perform the 
dielectric withstand voltage test 
and insulation resistance test 
between them.
