SIRIUS Safety Integrated (continued)
3RK3
3RK3 MSS ASIsafe
3RK3 Modular Safety System (MSS)
• Freely configurable modular safety relays
• Safety-related applications up to PL e according to EN ISO 13849-1 or
SIL 3 according to IEC 62061 can be implemented
• High flexibility and planning reliability thanks to a modular design
• More space in the control cabinet and lower costs thanks to highly modular project data
• More functionality and time savings thanks to a software-configurable system
• Comprehensive on-site diagnostics with the SIRIUS Safety ES software and
diagnostics display
• Improved plant diagnostics and higher plant availability thanks to exchange of data using
PROFIBUS
• Automatic creation of plant documentation with regard to MSS and software parameterization
• Up to 9 expansion modules can be plugged in for standard I/Os and fail-safe I/Os – optionally
solid-state or relay-based fail-safe outputs
• Graphic parameterization of the logic, online diagnostics, and automatic creation of
documentation using SIRIUS Safety ES
• Consistent further development of the safety monitors with the Advanced and ASIsafe central
units of the SIRIUS 3RK3 Modular Safety System (MSS)
Additionally with AS-Interface (ASIsafe):
• Modularly expandable and freely configurable safety monitor
• With MSS Advanced/ASIsafe up to 50 two-channel, fail-safe outputs (38 central outputs and
12 outputs via AS-i)
• Safety-related and standard communication between multiple MSS devices and/or safety
monitors
• Distributed detection of sensors and disconnection of actuators through AS-Interface
• Much more space is available without wiring outlay using AS-Interface
• Ready-to-use function blocks (e.g. muting or protective door with tumbler) can also be used
on AS-i

SC17.5F
AS-Interface safety modules
• Complete portfolio of ASIsafe modules
• For connection of safety switches with contacts (e.g. position switches) as well as solid-state
safety sensors (ESPE)
• Degree of protection IP65/IP67 or IP20
• Particularly compact dimensions, from 17.5 mm width
• Up to four safe inputs per module
• Up to one safe output per module
• Standard outputs are available on the module in addition
• Up to Category 4, PL e, SIL 3
Advantage: Easy integration of safe signals both in the control cabinet or in the field

CM AS-i Master ST and
F-CM AS-i Safety ST
AS-i Master and AS-i Safety module for ET 200SP
The CM AS-i Master ST and F-CM AS-i Safety ST modules are plugged into an ET 200SP
configuration, and they connect an AS-i network, including safety-related inputs and outputs,
with the controller.
• Single, double and multiple masters possible
• Up to 31 safe input signals (2-channel)/16 safe output channels possible per
F-CM AS-i Safety ST module
• Plant-wide safety programming of the F-CPU via SIMATIC Distributed Safety/Safety Advanced
• Pre-processing safe AS-i signals directly in the ET 200SP station is possible with an
ET 200SP F-CPU 1510SP F / 1512SP F (firmware V1.8 and higher), as is the configuration of
an autonomous AS-i Safety station without a higher-level CPU.
• Integrated diagnostics
• No other programming tools required
Advantage: Modular connection of fail-safe AS-i networks with system-wide programming in
SIMATIC and SINUMERIK controllers

3RM1
3RM1 motor starters
•
Motor starters for safety-related shutdown as 3RM11 direct-on-line starters or 3RM13 reversing
starters
• Compact devices with 22.5 mm width comprising combinations of relay contacts and power
semiconductors (hybrid technology) and a electronic overload relay
• For switching three-phase motors up to 3 kW (at 400 V) and resistive loads up to 10 A at
AC voltages up to 500 V under normal operating conditions
• Safety-related shutdown according to PL e or SIL 3 by shutting down the control supply
voltage possible without additional devices in the main circuit
• Combination with 3SK safety relay through conventional wiring or 3ZY12 device connectors
• Simple wiring and collective shutdown with device connectors in assemblies; there is no
further need for complex looping of the connecting cables
