DC Current Summation Transducer

DIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN rail cases.

Used to conver various inputs into standard DC signals for driving panel meters and for use in control devices.

M100-DS1 DC Current 1 input
M100-DS2 DC Current 2 inputs
M100-DS3 DC Current 3 inputs
M100-DS4 DC Current 4 inputs

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.
