4.2 Power Supply Specifications
4.1.1 Dielectric withstand voltage test and insulation resistance test
Perform dielectric withstand voltage test and insulation resistance test at the following voltage between each
terminals and the main unit ground terminal.
4.2 Power Supply Specifications
The power supply specifications for the main unit are explained below.
4.2.1 AC power type
*1. This item shows values when all 24 V DC service power supplies are used in the maximum
configuration connectable to the main unit, and includes the input current (5 or 7 mA per point).
4.2.2 DC power type
*2. There power consumption values are maximum values which include consumption of all expansion
equipment and input current (5 or 7 mA per point).

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