TVA-101-U0

Galvanic isolation of standard signals


isolation amplifier TVA-101
block diagram isolation amplifier TVA-101

Advantages

  • Inputs 
    • 0..20mA
    • 4..20mA
  • Outputs 
    • 0..20mA
    • 4..20mA
  • Galvanic isolation with 1kV~
  • Supply by input signal
  • No auxiliary power

Application description

The isolation amplifier TVA-101-U0 is used to galvanically isolate a electrical current signal when no auxiliary power is available. This is the case in complex measurement and control circuits where currents must be decoupled. By the use of this isolation amplifier the mutual influence of multiple signal current circuit can be excluded.

Function description

The dual isolation amplifier TVA-101-U0 is conceived for assembly on rail fastening appropriate to DIN EN 50022 - 35. The device operates without separate auxiliary voltage. The needed auxiliary power is withdrawn from the input signal current circuit. The current or voltage signal is supplied to the input of the isolation amplifier and will than be transferred galvanically isolated to the output. The secondary generated signal equals 1:1 the signal of the input circuit. Zero and end value are fix adjusted and can not be changed.
