[2] Wiring and setting of safety circuit
[1] Power
supply
If a safety circuit is configured using safety relays and contactors of 24 V specifications, it is recommended to
use a separate power supply from the power supply for controllers of 24 V specifications (ACON, PCON etc.).
It can be configured using the common power supply between the two, but breakage may occur when falsely
wired.
[2] System I/O connector specification
