我司與世界著名的多家PLC產(chǎn)品維護服務(wù)提供商建立了緊密的合作關(guān)系,北美、歐洲、亞洲您多能看到我們的身影。我們售出的DSC PLC模塊 備件提供一年的質(zhì)量保證,并且都經(jīng)過了嚴格的測試和認證。
產(chǎn)品優(yōu)點:使用安全PLC 及安全網(wǎng)絡(luò)的優(yōu)點包括:
1 機械控制更大的集成性和靈活性
2 當標準控制層智能化時,能夠進行更容易的故障診斷
3 更快、更方便的維護
4 減少安裝、調(diào)試以及重新配置的費用
5 與對于邏輯單獨使用安全繼電器相比,降低了設(shè)計和硬件成本
6 提高復(fù)雜系統(tǒng)生產(chǎn)性能的潛在能力通信
德國(SIEMENS)公司生產(chǎn)的可編程序控制器在我國的應(yīng)用也相當廣泛,在冶金、化工、印刷生產(chǎn)線等領(lǐng)域都有應(yīng)用。(SIEMENS)公司的PLc產(chǎn)品包括LOGO,s7200,s7300,s7400,工業(yè)網(wǎng)絡(luò),Hil人機界面,工業(yè)軟件等。
S7系列PLC體積小、速度快、標準化,具有網(wǎng)絡(luò)通信能力,功能更強,可靠性更高。s7系列PLc產(chǎn)品可分為微型PLc(如s7200)
小規(guī)模rl生能要求的PLc(如s7300)和中、高性能要求的PLc(如s7400)等。
SIMATIC S7-200 PLC
s7200 PLc是超小型化的PLc,它適用于各行各業(yè),各種場合中的自動檢測、監(jiān)測及控制等。s7200 PLc的強大功能使其無論單機運行,或連成網(wǎng)絡(luò)都能實現(xiàn)復(fù)雜的控制功能。
s7200Plc可提供4個不同的基本型號與8種CPU可供選擇使用。
s7300,模塊化微型PLc,滿足中小規(guī)模的性能要求。
SIMATIC S7400H:冗余的中央處理能力。
s7400 PLc是用于中、高檔性能范圍的可編程序控制器。s7400 PLc采用模塊化無風扇的設(shè)計,可靠耐用,同時可以選用多種級別(功能逐步升級)的CPU,并配有多種通用功能的模板,這使用戶能根據(jù)需要組合成不同的專用系統(tǒng)。當控制系統(tǒng)規(guī)模擴大或升級時,只要適當?shù)卦黾右恍┠0,便能使系統(tǒng)升級和充分滿足需要。
