Multiplier Isolation Amplifier

back to products


The multiplier separation amplifier AD-TV 12 GX in the narrow 6.2 mm housing serves the galvanic separation, amplification and conversion or adaption of analogue measuring signals and, at the same time, the multiplication of the input signal. The compact housing contains two synchronous output channels. All output channels are galvanic separated from each other, from the input and from the supply voltage. The type of signal can be freely selected at the input and the signal is multiplied onto the two current outputs. The standard signal combinations can be selected via the DIP switches at the side of the unit. Additionally, the separation amplifier has a highly efficient electronic power pack, which admits high loads at the two current outputs and causes low heat development. The unit can also be supplied via a hat rail connector, available as option; therefore several units in the GX series can sit side by side on the hat rail and the supply voltage must only be laid on once.


Galvanic separation or conversion of analogue standard signals with simultaneous multiplication.
