1762-MM11762-MM11762-MM1为了实现输入输出电路上的完全隔离，近年来在控制系统中光电耦合得到广泛应用，已成为防止干扰的***有效措施之一。光电耦合器具有以下特点:首先，由于是密封在一个管壳内，不会受到外界光的干扰;其次，由于靠光传送信号，切断了各部件电路之间地线的联系;第三，发光二极管动态电阻非常小，而干扰源的内阻一般很大，能够传送到光电耦合器输入输出的干扰信号就变得很小;第四，光电耦合器的传输比和晶体管的放大倍数相比，一般很小，远不如晶体管对干扰信号那么灵敏，而光电耦合器的发光二极管只有在通过一定的电流时才能发光。因此，即使是在干扰电压幅值较高的情况下，由于没有足够的能量，仍不能使发光二极管发光，从而可以有效地***掉干扰信号。由于光电耦合器的线性区一般只能在某一特定的范围内，因此，应保证被传信号的变化范围始终在线性区内。为了保证线性耦合，既要严格挑选光电耦合器，又要采取相应的非线性较正措施，否则将产生较大的误差。备货，备货，降降降，火火火，火火火……————————————————————————————————公司名称：厦门泰尼电气有限公司联系人：小黄（销售代表）联系电话：0592-6809319传真号码：0592-6890859（麻烦备注01006收）手机：18950191386***号码:2917675397邮箱：2917675397@***.com诚信经营，质量为首，诚信至上，泰尼电气小黄竭诚为您服务！！！———AudiocodesMediant200016T1/16E1SIPVoIPGatewayAudiocodesTP1610/480/16Sp​ancPCITP-161016T1/16E1AudiocodesMediant20008T1/8E1SIPVoIPGatewayNaturalMicroSystemsNMSCG6500C16T1/16E19600cPCINaturalMicroSystemsNMSCG65654T1/4E13200MIPSAudiocodesMediant20004T1/4E1SIPVoIPGatewayAudiocodesIPM260A4T1/4E1120channelSIPUniversalNaturalMicroSystemsNMSCG6500C8T1/8E13200MIPScPCIInetTektronixSpectraTurbo7SS7Analyzerw/8DLP+PoNaturalMicroSystemsNMSTX4000TX4000/20SS716LinksNaturalMicroSystemsNMSCG60004T1/4E13200MIPS50071NaturalMicroSystemsNMSAG40404T1/4E13200MIPSUniTektronixTFP2OTDROpti***06/11/16/17FS1315casedocNaturalMicroSystemsNMSAG40404T1/4E1UniversalNaturalMicroSystemsNMSCG6000C4T1/4E1cPCI5906+5908NaturalMicroSystemsNMSAG4040C4T1/4E1cPCINaturalMicroSystemsNMSAG40004T1UniversalP/N5605NaturalMicroSystemsNMSAG4000C4E1cPCIP/N5667NaturalMicroSystemsNMSAG4000C4E1cPCIP/N5668+5754AmeritecNiagraAM2-AAnalogBulkCallGeneratorNaturalMicroSystemsNMSAG40004T1PCIP/N5605NaturalMicroSystemsNMSAG40002E1120PCI/PCIx5610NaturalMicroSystemsNMSAG40002T1UniversalP/N5608NaturalMicroSystemsNMSAG40002T11600MIPSPCI5823NaturalMicroSystemsNMSAG40001T1Universal5820PCIxAmeritecNiagraAM2-DeDigitalE175ohmCallGeneratorAdtech401400Spirentw/HighSpeed,L2ATM,L3EtherNaturalMicroSystemsNMSAG40002T1PCIP/N5608AdlinkcPCIS-6130RcPCI1Uchassisw/cPCI-6770/P7CPUAmeritecAM7CentralOfficeSwitchw/4T1,2Loop,4ToneAdtech401400Spirentw/HighSpeed,L2ATM,L3PPPNaturalMicroSystemsNMSAG4000C2E1cPCIP/N5750Adtech400120Chassis+401427EthernetControlModuleAmeritecAM7CentralOfficeSwitch+(10)LoopGndStartVegaStreamVega508FXSAnalogVoIPGatewaySIPVegaStreamVega508FXOAnalogVoIPGatewayH.323Adtech401317FrameRelaySynchronousInterfaceAX/4000NaturalMicroSystemsNMSAG4000C4T1cPCIP/N5665AudiocodesMP118MP-118FXSAnalogGatewaySIPVoIPAdtech401311Spirent155.52MbpsG/A-ATM+FRenabledAudiocodesMP108MP-108FXOAnalogGatewaySIPVoIPAdtech401311Spirent155.52MbpsG/A-ATMenabledAdtech401311Spirent155.52MbpsG/A-FRenabledAdtech401382IP(L3)POS/ATM/FROC-3c/OC-12c***IFAdtech401383IP(L3)POS/ATM/FROC-3c/OC-12cMMIFMediatrix1204SIPAnalogGateway4FXOPortsAudiocodesMP104MP-104FXOAnalogGatewaySIPVoIPNaturalMicroSystemsNMSHyperT3DS3cPCIModel80817Adtech400301OC-3c/STM-1SingleModeInterfaceAX/4000Adtech400302DS3InterfaceAX/4000Adtech400302ADS3/MonitorInterfaceAX/4000Adtech400305OC-3c/STM-1MultimodeInterfaceAX/4000Adtech400310ATM25.6InterfaceAX/4000Adtech400317622.08MbpsATMGenerator/Analy​zeAX/4000Adtech400320IP(L3)POS/FROC-48c/STM-16c***2.48GbpsAdtech400500AX/4000155.52MbpsV1Generator/AnalyzAdtech400503AControlModuleAX/4000Adtech400503BGPS/ControlModuleAX/4000Adtech400504ControlModuleAX/4000AdtechAX/4000155.52MbpsV1Generator—————————————————————————————)
