Parameter list. Gönnheimer D 122 Z.0, D 122 Z, D 122 Z.3, D 122 Z.5

Below you will find brief information for totalizer D 122 Z, totalizer D 122 Z.0, totalizer D 122 Z.3, totalizer D 122 Z.5. The totalizer D122.Z operates in hazardous area and indicates the sum of measured values of a 4 up to 20 mA current circuit. The device gets its energy from the measure circuit, therefore an extra power supply or batteries are unnecessary. The totalizer measures the current, adds the previous values, scales the sum and displays the sum finally on the LCD.
