The new SIRIUS 3RK3 modular safety system (MSS) from Siemens Energy & Automation, Inc. is the ideal solution for applications that require the simplicity of safety relays and the added functionality of a fail-safe programmable logic controller (PLC).
It is recommended for use where more than
three safety functions have to be evaluated and where parameterizing
the wiring of safety relays would be very time-consuming and expensive.
Modular components allow operators to quickly and easily replace devices as
necessary and expand the system as the application requires. While the
modular structure provides high flexibility, it also saves space in the
control cabinet to reduce footprint costs. These features make the MSS
suited for use by OEMs, electrical distributors and panel builders, as
well as in conveyor, packaging, filling, and process logistics
applications.
Mighty modules
The SIRIUS MSS 3RK3 Basic consists of:
‚• Central module
‚• Expansion modules
‚• DP interface module
‚• Parameterization software
The
core of each MSS is the central module. The central module is designed
with eight safety-related inputs, one safety-related relay output, and
one safety-related solid-state output. Users can connect up to seven
expansion modules to the central unit for specific application
requirements. A variety of expansion modules are available and may be
combined as needed, including safety-oriented input modules, mixed
modules with safe inputs and relay or electronic outputs, and standard
output modules.
A non-safety related Profibus DP interface
module can be used for communication with higher-level controllers via
Profibus for enhanced diagnostics and device state data. The enhanced
data exchange improves plant diagnostics, availability and uptime.
Another key component of the SIRIUS MSS is its software. The system is quickly and easily parameterized with Modular Safety System ES
(MSS ES) software that eliminates time consuming wiring. All functions,
including safety and standard logic functions, are available as easily
connected blocks. The software also provides extensive on-site
diagnostics.
The MSS can be used in a wide range of industries worldwide for many different applications up to Category 4 in accordance with EN 954-1, Performance Level e in accordance with EN 13849-1
and up to SIL 3 in accordance with IEC 61508/62061. It is a
comprehensive stand-alone machine safety solution with a high level of
diagnostics, a space- and cost-saving design, and extremely flexible
application.
