4.3 Input Specifications
The main unit input specifications are explained below.
4.3.1 24V DC Input (sink/source)
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 for FX
3G-14M are X000 to X007.)
→ For details on sink input and source input, refer to Subsection 10.1.1
*1. Each value inside ( ) indicates the number of occupied points.
*2. Input impedance
*3. The "24V" and "0V" terminals are located on the output terminal side.
For details on the terminal layout, refer to Section 4.7.
