Wiring of Outputs of the 4/8 F-DI/4 F-DO DC24V/2A PROFIsafe Electronic Module

Use Case 1: Wiring a Load to Each Digital Output
Each of the four fail-safe digital outputs consists of one DOx P P-switch (current sourcing)
and one DOx M M-switch (current sinking). They connect the load between the P- and M-
switches. The two switches are always controlled so that voltage is applied to the load.
The wiring is carried out at the connection module.
