The VARIO-isolation amplifier AD-TV 32 GL serves the galvanic separation, conversion and amplification of DC current and voltage signals (0/4-20 mA and 0/2-10 V DC). The signal dimensions are adjustable at the front. The starting and end values can here be adjusted independent of each other. Input, output and the supply voltage are separate from each other with high insulation. An integral electronic wide range power pack with a high degree of effectiveness allows operation in a supply range of 20...253 V DC or 50...253 V AC. Additionally, a nominal value can be specified via switch at the front at the output. The input measuring signal is decoupled and without influence during this. The nominal value at the output, which can be activated and adjusted via a potentiometer at the front.



Conversion, burden amplification and galvanic decoupling of active DC-current and voltage signals with additional manual / automatic operation via a nominal value specification, which can be activated.

Specific characteristics

  • Front panel switch for switching between manual and automatic operation
  • Value setting for manual operation by front-face potentiometer
