IU-UU Measuring Transducer

Measuring transducer for converting a voltage (±30V / ±100V / ±270V) and a current (±7.5A / ±15A / ±30A / ±60A) into a ±10V standard signal up to 1 MHz.

Intended purpose:

The signal converter is intended for voltage and current measurement on electrical components from the automotive sector (e.g. motors, injectors, pump valves, etc.).

 

Highlights  

  • The measuring range of the current ±7.5A / ±15A / ±30A / ±60A to ±10V is switchable internally.
    There are no switched contacts in the current path.
  • Measurement of the current is isolated for the measurement output and isolated for the supply voltage.
  • If required, the measuring voltage can be supplied directly from outside to the selected measuring range ±30V / ±100V / ±270V to ±10V. This makes it possible to set up correct voltage measurement.
  • The voltage measurement is differential to the measurement output and isolated for the supply voltage.
  • Potential separation between measurement ground (AGND) and supply ground (GND).
  • The smaller measuring ranges are overload-proof up to the regular maximum measuring range 60A / 270V without damage.
  • Reverse polarity protection for operating voltage.
