The pulse divider AD-IU 214 GVC detects pulses arriving the input and gives out divided or multiplied pulses via its relay or transistor outputs. The input can be assessed freely. For evaluation of the input only whole number factors or divisors are possible. Mechanical contacts, NAMUR transmitter, active signals and semi-conductor switches can be connected and evaluated. The device can be parameterized by the customer via the optional PC configuration software AD-Studio, however, it can also be delivered preset. The inputs and outputs as well as the power pack are galvanic separated with high insulation. The transfer function of the device is: O = (I*(F1/D1)) O = output, I = input, F = factor, D = divisor



Dividing of any quantity signals, such as through-flows or energy. Application example of energy balance: Input: 1000 Imp/kWh Output: 10 Imp/kWh
