2. Wiring of PCS-DS51
This chapter describes the wiring of the PDS-DS51’s electric system and signal system such as
Ethernet control LAN, intelligent I/O, and P5 series parallel PI/O.
Wiring of Power Supply Cable
For the power supply of the main unit, intelligent I/O, and P5 series parallel PI/O, AC100V
external power is supplied through the receiving/distributing unit. This power supply is
distributed to the main unit and P5 series parallel PI/O in AC100V and to the intelligent I/O
converted to DC.

(Note) The I/O system power supply unit (DC24V)
is for the communication base unit only.
Isolate it from other external power supply
units (do not connect the I/O system power
common 0V and external power common
0V).
Don’t ground the I/O system power
common 0V.
