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.

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
