*1 When using a DC power supply type, it is the power source for an input extension block
between "24V" and "0V" terminals.
Never supply an external power supply to these terminals.
Moreover, do not connect any equipment except an extension block to these terminals.
*2 Never connect the "0V" and the "-" terminals of a DC power supply type main unit.

Main unit
Note: The input circuit power supply provides a clean
+24VDC supply for the inputs. Hence use an external
+24VDC power supply at your own risk.
The input circuit power supply cannot provide a
service supply to special function blocks (SFB). Use
an external supply to power the SFBs.
When using an AC powered unit, an external 24V DC
supply can be used.
Inputs 5.
