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).
The STO 081 has:
•8 secure outputs (EN 61131-2; EN IEC 62061 und EN ISO
13849)
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.
