Connection examples for semiconductor outputs
*Two loads may be connected to each safety output with advanced fault
detection, even on applications in accordance with EN IEC 62061, SIL
CL 3. Prerequisite: Feedback loop is connected, shorts across contacts
and external power sources are excluded (e.g. through separate multi-
core cables). Please note that, in the event of an error in the feedback
loop, the safety system switches to a safe condition and shuts down all
the outputs.
