  Description

The VARIO isolation amplifier AD-TV 30 GL serves to galvanically separate, convert and amplify DC current signals and voltage signals (0/4...20 mA and 0/2...10V DC). The signal sizes are adjustable at the front. The output signal follows the input size linear and is independent of the connected load up to a limiting value. Input, output and the supply voltage are galvanically separated from each other with a high degree of insulation. A highly efficient, integrated electronic wide-range power pack enables operation with 20...253 V DC or 50...253 V AC. There is no possibility of cross polarity of the connection voltage. A high packing density is achieved due to its narrow build.

  Application

Conversion, load amplification and galvanic decoupling of impressed DC current signals and voltage signals.
