Safety Systems

Simple, Yet Safe

Today, system operators expect their machines to comply with all requirements regarding functional safety and to offer state-of-the-art technology. At the same time, they want the machines to be fit for future requirements. Safety technology products by Siemens comply with the latest safety standards and have been certified for international applicability. The SIRIUS portfolio by Siemens features two safe evaluation devices: Safety relays and the modular safety system. No programming knowledge is required for either of these two evaluation device ranges. The safety relays and the modular safety system by Siemens thus support you with the easy and rapid realization of safe machines.
