SIRIUS modular safety system –
3RK3 Basic
Safety Integrated
The 3RK3 modular safety system is a modular,
software-parameterized safety relay
comprising:
• Central module, expansion modules,
DP interface module, diagnostic display,
and parameterization software.
The MSS 3RK is characterized by:
• High degree of flexibility and reliable
planning thanks to modular design
• More space in the control cabinet and lower costs due to a
bit-modular quantity structure
• Enhanced functionality and time savings thanks to a parameterizable
system
• Comprehensive diagnostics locally with the MSS ES software
• Better plant diagnostics, higher plant availability thanks to data
exchange over PROFIBUS
Flexible, fail-safe motor management –
SIMOCODE pro 3UF7
• Integrated safety functions for safe
shutdown of motors in automated
processes
• Two fail-safe digital modules
(DM-F Local, DM-F PROFIsafe) for
optimized, error-free integration of the
safety functions
• Processing of the safety shutdown signal from the fail-safe controller
or direct sensor interfacing with the DM-F Local; processing of the
safety shutdown signal from a fail-safe controller PROFIBUS /
PROFIsafe with the DM-F PROFIsafe
• Transmission of comprehensive diagnostics information via
SIMOCODE to the controller
• Compliance with the requirements of the IEC 61508/62061 and
ISO 13849-1 standards for functional safety up to SIL 3 or PL e
