d.c. current summation transducer, part of the hobut range

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 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.
