1 S-DIAS Safety Digital Output Module STO 081
The S-DIAS Safety STO 081 digital output module has the safety integrity
level SIL3 (EN / IEC 62061) or Performancelevel e (PL e) (EN ISO 13849-
1/-2). The STO 081 has:
•8 secure outputs (EN 61131-2; EN/IEC 62061 und EN ISO
13849-1/-2)
The safe outputs are used for the safety-oriented output of eight actuator
signals to, for example, control relays, valves, etc.
The safety-related STO 081 is ideal for use in systems with optional
modules and interface variables according to Safety System Handbook,
see homepage
1
.
To use the STO 081 in an application, at least one Safety CPU module that
regulates the synchronized communication with the safety modules using
safe bus telegrams is also required. This also includes
•processing the safe application and
•the distribution of configuration data to remote Safety
modules.

If the safety guidelines are not followed, danger to personnel can arise that could lead to
serious injury or in worst cases, death. In less serious cases, systems and equipment can be
damaged.
The following symbols identify the individual risks as well as the degree of seriousness; their
respective meanings are briefly explained. You should therefore familiarize yourself with the
safety symbols and their meanings to prevent dangers and risks.
DANGER!
DANGER!
Identifies an immediate danger with high risk, which
can lead to immediate death or serious injury if not
avoided.
Indique un danger direct à haut risque d’un décès
immédiat ou des blessures graves si les consignes de
sécurité ne sont pas respectées.
WARNING
WARNING
Identifies a possible danger with a mid-level risk, which
can lead to death or (serious) injury if not avoided.
Indique un danger possible d’un risque moyen de
décès ou de (graves) blessures si les consignes de
