24V DC Input Type (Common to Sink/Source Input)
The input specifications for the main unit, cautions on wiring the unit and examples of wiring are given below.
10.2.1 Input specifications (main unit)
The input numbers in the table indicate the main unit terminal numbers. "X010 or more" means the numbers
from X010 to the largest number that the main unit has.
(The input numbers of FX
3U
-16M are X000 to X007.)
