In other words the longer the integration time for an analog input channel,the more accurate the resolution of the measured value will be (see TechnicalSpecifications of the module and Table 4-6 on page 4-11).Analog Modules4-112S7-300 Programmable Controller Module SpecificationsA5E00105505-02Terminal connection diagram and block diagram of the SM 331; AI 8 12 bitsM3*Comp–/ ManaFault indicator – redThermocouples,voltage measurementcurrent measurementResistance testM0 +M0*M1 +Comp +SFInternal supplyMML+Current sourceMulti-plexerMeas. rangemoduleExt. compensationNoneADCIsolationBackplane businterfaceSF+Int.Comp.CH0 M0 + CH0M0*IC0 +CH1M1*IC0*M2 + CH2 M1 +CH2M2 *M1*M3 +CH3 IC1 +IC1*M4 +M4*M5 +CH4M2 + CH4M2*IC2 +CH5M5*IC2*M6 + CH6 M3 +CH6M6 *M3*M7 +CH7 IC3 +M7*IC3*Comp24VTFigure 4-38Module View...
