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
