DC Current Summation

DescriptionDIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN rail casesApplicationUsed to conver various inputs into standard DC signals for driving panel meters and for use in control devices.Selection GuideM100-DS1DC Current 1 inputM100-DS2DC Current 2 inputsM100-DS3DC Current 3 inputsM100-DS4DC Current 4 inputsTypical ApplicationsThe M100-DS series of summation transducer take up to four inputs and provide an output signal directly proportional to the sum of the inputs. A typical application is the summation of total kW of four seperating generating sets e.g. the four individual kW readings are provided by M100-WA4 transducers with 0-1mA output signals.The M100-DS4 summates the four 0-1mA signals and provides a single output signal that is directly proportional the sum of the total kW of all four generators. It is important to note the following when using summation transducers: to ensure the correct reading is obtained:The current and voltage ratios must be identical otherwise the subsequent summation will be meaningless.Technical SpecificationsINPUTRated value In±1mA 0-1mA-20mAVoltage drop20mVWorking Range±125%Overload Continuous4 x InOverload Continuous:1.5 x UnOUTPUTRated value mA0-1/5/10/20 & 4-20mALoad resistance12/2.4/1.2/0.6 kOhmRated value volts0-5 / 10 & 1-5VADJUSTMENTZero±2%Span±10%AUXILIARYA.C.
