Power module PM-E F
This module combines two functions. Not only can individual actuators (comparable with the
functionality of an F-DO module) be connected to all three two-channel output channels, but
the third DO2 output channel also has a further function.
The DO2 output channel is used to internally (no external wiring required) disconnect safety-
oriented (i.e. with two potentials) to supply power for the subsequent standard DO or also
standard DI modules. Namely, the outputs on the DO modules can not only be controlled
using a single channel in the PLC for the "normal" function, but also a safety-oriented
shutdown of the power supply for all DO modules following the PM-E F module is possible.
