Using Interference-Free Module in Safety Applications
Due to its interference-free feature, this S67-DIO8-M12×8 module is suitable
for passive use in safety circuits.
If the field-sided supply is switched off via a safety switching device, the safe‐
ty function of the module responses passively to the safety function. If the in‐
terference-free module is used correctly in a safety application, the "SIL" or
the "Performance Level" reached due to the switching as well as the category
are not affected. Refer to the following information and the connection dia‐
grams.
The absence of interference of the digital output modules is supported start‐
ing from the following technical module index:

NOTICE
Only a power supply unit specified for an "Extra-low-voltage with safe electri‐
cal separation" (SELV/PELV) can be used for the 24 V supply voltage.
NOTICE
The short circuit from a digital output to external voltages (e.g. 24 V field sup‐
ply voltages) results in a reverse feeding in of the field supply and thus a loss
of the safety function. To eliminate potential errors, wire connecting lines with
sufficient protection between the outputs of interference-free modules and ac‐
tuators acc. to EN 60204-1 or EN ISO 13849-2.
NOTICE
A short circuit between two digital outputs of interference-free modules is not
detected by the safety switching device. The two-channel switch-off of feed‐
back-free modules is not a safety function. It merely serves to functionally
switch off the actuators.
