    • 0..10V
    • 0..20mA
    • 4..20mA
    • PFM signal 90..520Hz

  • Outputs 2x

    • 0..10V
    • 0..20mA
    • 4..20mA

  • Galvanic isolation with 4kV~
  • Integrated sensor supply
  • 20...253V AC / DC wide range supply

Application description

The dual isolation amplifier TVA-200-U0 is used for galvanic isolation, for conversion of two signals into another signal or for adjustment of zero and/or end value of a signal.
The integrated sensor supply allows the direct connection and by this the supply of 2-wire-transmitters and of 3-wire-transmitters.

The variant with input PFM signal 90..520Hz in combination with a suitable PFM sensor e.g. fill level transmitter Hydrocont B is especially suitable for the signal transmission at long distances (multipe 1000m)

Function description

The dual isolation amplifier TVA-220-U0 is conceived for assembly on rail fastening appropriate to DIN EN 50022 - 35.

Because of the integrated wide input power supply for supply voltages from 20...253V AC and DC, the supply isolation amplifier is suitable for using in all common international energy supply networks.

The activation of the device is signalled by a front sided integrated green LED.
A connected sensor can be supplied per channel by an integrated sensor supply.
The current or voltage signal is supplied to the input of the respective channel of the isolation amplifier and will than be transferred galvanically isolated to the respective output.
