Operation with
safety light grid
If the STO function is operated with a safety light grid or a safety control, the reference
potential (0 V) is hard-wired on the input side. The two-channel shut down is then
performed by two safety outputs (monitored by the safety sensor) which provide the two-
channel supply for the STO function.

Operation with
Baumüller Safety
I/O terminal
SO4000
The output terminal SO4000 shown provides bipolar safety outputs. For connection of the
STO function, the 0 V switching output is wired with pin 2/5. The corresponding 24 V
switching output is wired with terminal pin 1/4.
Short circuits of the outputs of the Baumüller Safety output terminal SO4000 to supply
potentials or between the outputs are detected by the output terminal and lead to the shut
down.
