編者按：西門子工業(yè)自動(dòng)化有限公司（SIAS），建立于1995年，是西門子自動(dòng)化與驅(qū)動(dòng)集團(tuán)在中國(guó)的過(guò)程控制領(lǐng)域的工程公司。至今，SIAS已形成以行業(yè)為導(dǎo)向的業(yè)務(wù)開拓模式,并在自動(dòng)化領(lǐng)域具有獨(dú)特競(jìng)爭(zhēng)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(wù)。 2008年2月18日消息，西門子工業(yè)自動(dòng)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(tǒng)。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(tǒng)可被用于所有部門和必需評(píng)估一些安全功能，且和一些開關(guān)設(shè)備連接又很昂貴的應(yīng)用。 3RK3安全系統(tǒng)的模塊化設(shè)計(jì)可使用戶節(jié)省成本，用戶僅需要替換他們應(yīng)用中必需的替換的設(shè)備。同時(shí)，如果應(yīng)用改變了，他們可以將更多功能添加到設(shè)備中。系統(tǒng)的核心是擁有八個(gè)與安全相關(guān)的輸入系統(tǒng)、一個(gè)與繼電輸出相關(guān)的安全系統(tǒng)和一個(gè)固態(tài)輸出相關(guān)的安全系統(tǒng)。此外，用戶可以連接高達(dá)七個(gè)擴(kuò)展模塊，方便閱讀輸入、輸出安全功能。ADP接口模塊通過(guò)Profibus與高層控制器實(shí)現(xiàn)通信。借助于MSS ES參數(shù)化軟件的幫助，系統(tǒng)的零件部分，輸入和輸出信號(hào)可被設(shè)置，設(shè)備功能被互相連接。 ARC咨詢集團(tuán)Sal Spada評(píng)價(jià)說(shuō)：西門子已經(jīng)在機(jī)器安全防護(hù)部分做出了不懈的努力，Sirius 3RK3正是機(jī)器制造商所要尋找的。此產(chǎn)品在模塊化配置繼電器市場(chǎng)份額增長(zhǎng)了25％，Sirius 3RK3安全繼電器和安全PLC之間的過(guò)渡產(chǎn)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]
