Isolation Amplifier
AD-TV 452 GS

back to products


The multiplier separation amplifier AD-TV 452 GS 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 outputs. The standard signal combinations can be selected via the connector terminals at the side of the unit. Additionally, the separation amplifier has a highly efficient electronic power pack, which admits high loads at the two outputs and causes low heat development.


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