AD-TW 21 GVD, AD-TW 25 GVD

Description

The passive AC current separation transducer serve the conversion of AC currents of magnitudes 0-1 A AC or 0-5 A AC in an impressed DC current of 0-20 mA. The galvanically separated output signal is, up to a maximum value, independent of the connected burden. The separation transducer does not require an auxiliary energy, the necessary energy is gained from the measuring signal.

AD-TW 21 GVD, AD-TW 25 GVD

Application

Remote transmission of current transducer signals, galvanic separation and coupling to systems with 0-20 mA inputs.

Specific characteristics

  • for 1 A AC or 5 A AC current transducer signals
  • galvanically separated output 0-20 mA
  • no auxiliary energy required
  • connection terminals can be pulled off
