6SC6112-0AA00模块6SC6112-0AA00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。PanasonicACServoDriverDriverMSD043A1XXVFreeShippingWorldwideTexasInstruments7MT700YASKAWAELECTRICSGDA-08VSUSPPSGDA08VSASEABROWNBOVERI57120001-HA/1USPP57120001HA1PERCEPTRONTUNNELMOUNTREPEATER926-0127-01CONTROLTECHNIQUESDXE-430USPPDXE430PanasonicACServoMotorM***012A1EEFreeShipCONTROLTECHNIQUESCDE-150NSFPCDE150TEXASINSTRUMENTSPLC505-2595USPP5052595IMPCO14339ANSFP14339AASEABROWNBOVERIACS501-025-4-0​0P5USPPACS501025400P5HONEYWELL51309148-175NSPP51309148175TEXASINSTRUMENTSPLCPWB-2461414-00​01USPPPWB24614140001SIEMENS6ES7-215-2BD00​-0XB0USPP6ES72152BD000X​B0PanasonicACServoMotorM***A021A1FFreeShipGENERALELECTRICDS3800DMPCUSPPDS3800DMPCTexasInstrumentsRTU84502ModemBoardASEABROWNBOVERID***C-110NSPPD***C110TexasInstruments510-7105TEXASINSTRUMENTSPLC505-4316AUSPP5054316AALLENBRADLEY1336-B015-EAE-​FA2-L3USPP1336B015EAEFA2​L3GENERALELECTRIC193W-532ACG04USPP193W532ACG04TEXASINSTRUMENTSPLC100-3101USPP1003101PanasonicACServoDriveDV451S200#37773TEXASINSTRUMENTSPLC55CI8602700017USPP55CI8602700017PanasonicACServoDriverMSDA043A1ANewinBoxFreeShipASEABROWNBOVERI7525A67G10NSPP7525A67G10USEDPerceptron912-0045EMinicamSurfaceSensorALLENBRADLEY1336F-BRF50-AA​-EN-HCS2-LA2-L​A3-L4USPP1336FBRF50AAEN​HCCUTLERHAMMERHMCP400J5CNSFPHMCP400J5CASEABROWNBOVERIYT204001-JJUSPPYT204001JJASEABROWNBOVERI57310001-S/4USPP57310001S4TISiemensCTi500-2151-A5002151PowerSupply2151APLCPanasonicMGMA092A1GACSERVOMOTORFreeShipTEXASINSTRUMENTSPLCPWB-2461414-00​01USPPPWB24614140001PanasonicACServoDriverMSDA043A1ANewinBoxFreeShipTEXASINSTRUMENTSPLC500-5013NSFP5005013TEXASINSTRUMENTSPLC505-CP1434TFNSFP505CP1434TFTEXASINSTRUMENTSPLC505-3516USPP5053516Panasonic3.0kWACServoMotor***302D1C(freeshipping)AUTOTECH140SAC-QDNET-0​10USPP140SACQDNET010ASEABROWNBOVERI57772158USPP57772158PERCEPTRONUS400D45VTEXASINSTRUMENTSPLC435-DC-CPUNSFP435D***UASEABROWNBOVERI(ABB)DSDP140BCONTROLOTRON994DN5GS-3NSPP994DN5GS3TEXASINSTRUMENTS500-2151-APOWERSUPPLY5002151A(AG01)PANASONICM***A042A1BACSERVOMOTORWORKINGPANASONICACSERVODRIVEDV80X050LD4DV80X050LD4DV80X-050LD4HITACHISEIKISQUARED30528-001-57NSFP3052800157FANUCA860-0346-T041USPPA8600346T041ASEABROWNBOVERI3HAA3563-AHA/2USPP3HAA3563AHA2TEXASINSTRUMENTSPLC7MT-100AUSPP7MT100APERCEPTRON495-0191USPP4950191ALLENBRADLEY813S-VOHUSPP813SVOHTEXASINSTRUMENTSPLC5110-10USPP511010OnePanasonicACServoDriverM***A013A1AFreeShipTEXASINSTRUMENTSPLC530-1104USPP5301104SIEMENSTEXASINSTRUMENTS505-7028AXLNTFASTSHIPPINGTEXASINSTRUMENTSPLC164-1112USPP1641112LAMARCHEA12B-20-48VUSPPA12B2048VTEXASINSTRUMENTS5TI-20015TIPROGRAMMERINCASE*SEWEURODRIVET4616.0USPPT46160ASEABROWNBOVERI57088478USPP57088478TexasInstruments500-5019505-6851BTexasInstrumentsSiemens505-6851BN6PanasonicM***D012S1AACServoMotorNEWFreeShipASEABROWNBOVERI3HAA3560-DZA/5NSPP3HAA3560DZA5ASEABROWNBOVERIACS601-0100-4-​000B1200801USPPACS60101004000​B1TOSHIBAVT130G2-4080USPPVT130G24080ASEABROWNBOVERIDSSR-115USPPDSSR115MITSUBISHIA1SJ71E71N-B2NSFPA1SJ71E71NB2)
