Redundant output
Single output
Single output with advanced fault
detection*
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 multicore 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.
