Digital output
Attention
protected wiring
If the wiring of the outputs or the connected actuators leaves the control cabinet, the user
must ensure that the wiring is protected.
WARNING
Active loads
The use of active loads (with their own power supply) is not permissible unless the manu-
facturer of the load ensures the non-reactivity of the power supply to the control signal.
DANGER
Clocked signals inside a sheathed cable
If clocked signals from different output modules are used inside a single sheathed cable,
then a module error such as a cross-circuit or external power supply must lead to the
switch-off of all of these modules. This switch-off must be executed by the user program.
5.4.1
Parameterization
The outputs are parameterized via the
Safety Parameters
tab of the alias devices. A TwinSAFE EJ output
module consists of four channels.
