500-5018***500-5018***500-5018***机械安全是一项复杂的系统工程,需要考虑的因素很多,比如机械设备特点、工艺操作特点、安全设计理念等等。一般来说,安全控制系统应该包括安全输入设备(如急停按钮、安全门限位开关或联锁开关、安全光栅或光幕、双手控制按钮),安全控制电气元件(如安全继电器、安全PLC和安全总线)和安全输出控制(如主回路中的接触器、继电器或阀等)。其中,安全PLC是在应用中值得***关注的产品。所谓安全PLC,就是专门为条件苛刻的任务或安全相关的应用而设计的PLC,在其失效时不会对人员安全或过程安全带来***。在一台安全PLC根据要求达到了特定的可靠性/故障概率等级时,就意味着它具有广泛的自诊断能力,可以监测各个方面的硬件状态、程序执行状态和操作系统状态。此外,安全PLC还必须能够执行标准机构(例如TUV、FM等)认证的必须的故障安全动作,而这些故障安全动作都是根据特定的原则设计,并满足安全标准(如IEC61508和EN954-1等)中定义的要求。另外,安全PLC还可能包括警卫保护预警和权限管理的内容,用来保护安全PLC不受来自外界的干扰。从范围看,实践证明已经采用安全PLC的行业包括汽车、机床、机械、船舶等行业,以及过程工业中的石化、炼油、电厂、锅炉控制和燃烧控制、高压应用等。此外,它还可以在一些远程遥控、无人值守以及维护费用十分昂贵的应用场合(例如大型储罐区)一显身手。TEXASINSTRUMENTSPLC555-1101USPP5551101AYDINCONTROLS460-5164-ABUSPP4605164ABMITSUBISHIA3A-CPU-P21USPPA3ACPUP21TEXASINSTRUMENTSPLC2497993USPP2497993ASEABROWNBOVERIACH501-005-4-00P2USPPACH501005400P2ExpeditedshippingailableASEABROWNBOVERI57411490USPP57411490FOXBORO130FD-NUSPP130FDNALLENBRADLEY22B-D012N104FNFP22BD012N104ALLENBRADLEY8600-2079PUSPP86002079PTEXASINSTRUMENTSPLCVPU-200USPPVPU200NewinBox505-7028TexasInstruments/Siemens5057028N741TexasInstrumentsProgrammerTI101Model100-3101NEWPERCEPTRONCAMERADigitalCONTOURSENSOR916-4128TexasInstrument500-4010loopaccessmodulePanasonicACServoMotorM***02A1EFreeShipPanasonicMQDB011AAD03ACServoDriver0190-19214workingASEABROWNBOVERI3HAA0001YUNSPP3HAA0001YUALLENBRADLEY1772-M3NSFP1772M3GENERALELECTRICDS3800HLOA1E1CUSPPDS3800HLOA1E1CCUSTOMSERVO398111-01CNSPP39811101CALLENBRADLEY160-BA04SF1-AF-D13-DN2C-DNRC-DNSC1-DSUSPP160BA04SF1AFD13DASEABROWNBOVERIQK-140-1R6500USPPQK1401R6500TEXASINSTRUMENTS500-50235005023ELECTROCRAFTPDM10USPPPDM10TEXASINSTRUMENTSPLC500-2101USPP5002101TexasInstruments305-01ABTexasInstruments32Pt24/110OutputMN500-5056EDISONCONTROLS1010617-B400-A3.0NSFP1010617B400A30ASEABROWNBOVERIYTE-102CUSPPYTE102CTEXASINSTRUMENTSPLCPM550-302USPPPM550302TexasInstruments5TI-5500ASEABROWNBOVERI3BHT300025R1NSPP3BHT300025R1TEXASINSTRUMENTS520C-1102SERIES500CONTROLLERREV2.6520C1102PanasonicACServoDriverMSDB3A2AAD02New0190-26756KEYENCECORPPI-C92NSFPPIC92ASEABROWNBOVERILSB-6-3-600-LUM2USPPLSB63600LUM2ASEABROWNBOVERIYYT-102CUSPPYYT102CTexasInstruments30504Bw/32507/305-20N/305-20TTEXASINSTRUMENTSPLCPM550-100USPPPM550100TEXASINSTRUMENTS5TI-1034-1USEDSEQUENCERMODULE5TI10341TexasInstruments7MT700TEXASINSTRUMENTSPLC500-5020NSPP5005020PanasonicACServoDriverMSDZ011A1A07FreeShipASEABROWNBOVERIDSQC266AUSPPDSQC266AReturns:Acceptedwithin7daysOMRONCS1W-SLK21USPPCS1WSLK21TEXASINSTRUMENTSPLCPM550-210USPPPM550210ALLENBRADLEY1771-IFE/CNSPP1771IFECPanasonicACServoDriverMSD5A3A1XX19FreeShipTEXASINSTRUMENTSPLC5TI-5339USPP5TI5339MAZAKPD14BUSPPPD14BTEXASINSTRUMENTS520C-1102SERIES500CONTROLLERREV2.6520C1102PanasonicACServoDriverMSD043A1XFreeShipPanasonic2.5kWACServoMotorM***252A3JFreeShipASEABROWNBOVERI3ADT306200R1NSPP3ADT306200R1FISHERROSEMOUNTDH6003X1USPPDH6003X1NewPerceptron926-0127RepeaterAssembly46-650-1229EnclosureTexasInstruments2493295-0002HONEYWELL51401491-100USPP51401491100ASEABROWNBOVERIACS501-010-6-X00P5USPPACS5010106X00P5OMRONCV500-MC221USPPCV500MC221TEXASINSTRUMENTSPLC505-4732USPP5054732)
