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.

Function description

The dual isolation amplifier TVA-200-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.
Inside the housing the different input and output signals can be set by dip switches in arbitrary combinations.

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.

The signal of the respective output can be adjusted at zero against the nominal value by -25%...+5% and at the end value against the nominal value by -5%...+45% by front-sided trimming potentimeter
