4 Specifications, External Dimensions and Terminal Layout (Main Units)

Perform dielectric withstand voltage test and insulation resistance test at the following voltage between each
terminals and the main unit ground terminal.

The power supply specifications for the main unit are explained below.

*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).

*2.

There power consumption values are maximum values which include consumption of all expansion

equipment and input current (5 or 7 mA per point).
