DC CURRENT SUMMATION
	SELECTION GUIDE M100-DS1 DC current 1 input M100-DS2 DC current 2 inputs M100-DS3 DC current 3 inputs M100-DS4 DC current 4 inputs TYPICAL APPLICATIONS The 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 separate 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.
