AD-TV 400 GVD

Description

The isolation amplifier AD-TV 400 GVD serves the galvanic separation of analogue signals and of transmitter signals. When a 2-wire transmitter is connected, this will be supplied directly via a galvanically separated and current-limited supply voltage. All measuring ranges and outputs can be freely parameterized. This can be carried out via the optional operating panel AD-VarioControl or via the programming software AD-Studio. The wide bipolar input measuring range makes this buffer amplifier into the universal type for almost all applications in the area of standard signals and beyond. Due to its current-sinking output, transmitter signals can also be separated or converted. All supply ranges are covered with the wide range power pack.
