S-DIAS Safety Relay Output Module SRO 021
The S-DIAS Safety SRO 021 relay output module has the safety
integrity level
SIL3 or SIL CL 3 (EN / IEC 62061) or
Performancelevel e (PL e) (EN ISO 13849-1/-2). The SRO 021
has:
•
2 Safe outputs (EN 61131-2; EN/IEC 62061 und EN ISO
13849-1/-2)
The safe outputs are used for the safety-oriented output of two
actuator signals to, for example, control relays, valves, etc.
The safety-related SRO 021 is ideal for use in systems with
optional modules and interface variables according to Safety
System Handbook, see homepage

.
To use the SRO 021 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
