*7. When analog special function blocks (FX0N-3A, FX2N-2AD and FX2N-2DA) are connected to an input/
output powered extension unit (FX2N-32Eîš… or FX2N-48Eîš…), the following limitation must be taken into
consideration. (When the blocks are connected to the main unit, this limitation is not applied.)
The total current consumption of the analog special function blocks (FX0N-3A, FX2N-2AD and FX2N-
2DA) should be less than the following current values.
- Total current consumption of blocks connected to FX2N-32Eîš…: 190 mA or less
- Total current consumption of blocks connected to FX2N-48Eîš…: 300 mA or less
*8. When applying the DC power type main unit, calculate the current consumption at startup.
