1790P-TN4C0输入模块1790P-TN4C0输入模块1790P-TN4C0输入模块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。ASEABROWNBOVERI1913JA002100000USPP1913JA002100000ASEABROWNBOVERIYPQ-110AUSPPYPQ110ALITTELFUSEKLPC-3500AUSPPKLPC3500ATEXASINSTRUMENTSPLC500-5027NSPP5005027PanasonicServoMotorM***042P1A400WFreeShipTexasInstruments(Siemens)TI-435PLCw/RackModulesSIEMENS6ES5-324-3UR11USPP6ES53243UR11NSDV8L55-11NSPPV8L5511ALLENBRADLEY809-A12ENSPP809A12EASEABROWNBOVERIYPP-110AUSPPYPP110ATexasInstruments500-5053BasicModule#7334PanasonicACServoDriverMSD043A1XXFPanasonicACServoDriverMSDA043A1ANewinBoxFreeShipTEXASINSTRUMENTSPLCPM550-400USPPPM550400PanasonicACServoDriveMBDHT2510ENewinBoxFreeShipTELEMECANIQUETSX-P67-3USPPTSXP673ASEABROWNBOVERI57275758NSFP57275758TexasInstruments505-6108DATALOGICDS6300-100-010USPPDS6300100010Panasonic-MinasACServoDriverMSD023A1XASEABROWNBOVERIAPTBK-02USPPAPTBK02TEXASINSTRUMENTSPLC505-4908USPP5054908PERCEPTRON911-0053USPP9110053FANUCA20B-2001-0060USPPA20B20010060TEXASINSTRUMENTSPLC505-7340USPP5057340NewPanasonic/NaisServoM***D042P1U+MBDDT2210ASEABROWNBOVERIYT212001-AGUSPPYT212001AGALLENBRADLEY196258USPP196258ABBASEABROWNBOVERIQIPA-121CONTROLUNITPRESSDUCTORPILLOWBLOCK57306PanasonicACServoDriverMSD5A3A1XX19FreeShipASEABROWNBOVERIYT204001-FCUSPPYT204001FCTEXASINSTRUMENTSPLC500-5039NSFP5005039TEXASINSTRUMENTSPLC505-7101USPP5057101ASEABROWNBOVERI3HAA3573-ACANSPP3HAA3573ACAPANASONICAMKB300B20KAHACSERVOMOTORNEWPERCEPTRONCAMERATRICAMSURFACESENSOR912-0014SYMAX8881-MD2USPP8881MD2TexasInstrument500-5019WordOutputModuleTEXASINSTRUMENTSPLC505-5190NSFP5055190SQUAREDLH-36250USPPLH36250TEXASINSTRUMENTSPLC945145-0004-AAUSPP9451450004AAASEABROWNBOVERIDSQC314BUSPPDSQC314BASEABROWNBOVERI289B456A13NSPP289B456A13ASEABROWNBOVERIDSQC-266CUSPPDSQC266CTexasInstruments505-4232TEXASINSTRUMENTSPLC505-6202NSFP5056202FINCOR5002693USPP5002693TISiemens500-21515002151PowerSupply2151APLC,PictureprovideuponrequestGENERALELECTRIC9L10MAL334USPP9L10MAL334PanasonicACServoDriverDriverMUDS023A1MNewinBoxFreeShipTEXASINSTRUMENTSPLC55PL8312000328USPP55PL8312000328TEXASINSTRUMENTS505-6108BUSPP5056108BPanasonicACServoDriveMBDHT2510EFreeShipTEXASINSTRUMENTSPLC500-5023NSPP5005023TEXASINSTRUMENTSPLC500-9940USPP5009940SIEMENSCBA20885USPPCBA20885PanasonicM***022J1SXACServoMotorwith60daywarrantyASEABROWNBOVERI58116076USPP58116076TEXASINSTRUMENTS5TI-20015TIPROGRAMMER*NEW?TexasInstruments500-2109CommunicationModuleAssemblyASEABROWNBOVERIYB161100-BBUSPPYB161100BBKEYENCECORPLC-2100USPPLC2100TEXASINSTRUMENTSPLC140-1111USPP1401111)
