編者按：西門子工業自動化有限公司（SIAS），建立于1995年，是西門子自動化與驅動集團在中國的過程控制領域的工程公司。至今，SIAS已形成以行業為導向的業務開拓模式,并在自動化領域具有獨特競爭能力。新年伊始其就推出了模塊化安全解決方案，為用戶提供全面服務。 2008年2月18日消息，西門子工業自動化公司正在推出模塊化安全解決方案：Sirius 3RK3模塊化安全系統。Sirius 3RK3被安裝在安全繼電器和故障安全控制器之間。3RK3安全系統可被用于所有部門和必需評估一些安全功能，且和一些開關設備連接又很昂貴的應用。 3RK3安全系統的模塊化設計可使用戶節省成本，用戶僅需要替換他們應用中必需的替換的設備。同時，如果應用改變了，他們可以將更多功能添加到設備中。系統的核心是擁有八個與安全相關的輸入系統、一個與繼電輸出相關的安全系統和一個固態輸出相關的安全系統。此外，用戶可以連接高達七個擴展模塊，方便閱讀輸入、輸出安全功能。ADP接口模塊通過Profibus與高層控制器實現通信。借助于MSS ES參數化軟件的幫助，系統的零件部分，輸入和輸出信號可被設置，設備功能被互相連接。 ARC咨詢集團Sal Spada評價說：西門子已經在機器安全防護部分做出了不懈的努力，Sirius 3RK3正是機器制造商所要尋找的。此產品在模塊化配置繼電器市場份額增長了25％，Sirius 3RK3安全繼電器和安全PLC之間的過渡產品。 [FONT=times] original text [/FONT]

[font=times][Color=#708090]February 18, 2008 – Siemens Industrial Automation is launching a new safety solution, the Sirius 3RK3 modular safety system. The Sirius 3RK3 is positioned between a simple safety relay and a fail-safe controller. The 3RK3 safety system can be used in all sectors and applications in which several safety functions have to be evaluated but where it would be too costly to wire together several switching devices. The modular design of the Sirius 3RK3 safety system enables users to save costs since they only have to replace those devices that are really necessary for the application. At the same time, they can add more functions to the device unit if the application changes. The core of the system is the central unit with eight safety-related inputs, one safety-related relay output, and one safety-related solid-state output. In addition, users can connect up to seven expansion modules that can read in and output further safety functions. A DP interface module enables communication with higher-level controllers via Profibus. With the help of the MSS ES parameterization software, a component part of the system, input and output signals are set and device functions are interconnected. Sal Spada, ARC Advisory Group, commented, "Siemens has been making continuous strides in the machine safeguarding sector, and the Sirius 3RK3 is what machine builders are seeking. This product fits squarely in the Modular Configurable Relay niche of the market that has been growing by over 25 percent. Effectively, the Sirius 3RK3 provides a transitional product between Safety Relays and SafetyPLCs." [/color][/font]
