Signal behavior

The safe state is the switched off state (unpowered
state: logical "0" on an OSSD).
If the actuating element is in the enable zone and there
is no sensor error, both output stages (OSSD) are
enabled (logical "1").
The output parameters are compatible with the pa-
rameters for the input as per EN 61 131-2 type 1 or 2:
Logical "1"
Logical "0"
If the actuating element is outside the enable zone, the
outputs are switched off (logical "0"; safe state).
Cross-circuits between the two outputs will be
detected by the safety switch and result in the
shutdown of the outputs (OSSD).
Cross-circuits between the supply voltage and an
output will be detected and result in the shutdown of
the other output.
