Voltage Measurement

Voltage measurement can only be performed via U/I transformer!
Voltage measurement cannot be performed via multiplier at the analog inputs,
since the internal resistance of the TO-PASS
input current.
WAGO 857 Series JUMPFLEX Isolation Amplifiers for level conversion may be
used for voltage measurement via TO-PASS
