block diagram pt100 signal converter; WTAU-220-U0

Application description

The Pt100 signal doubler WTAU 220-U0 is used to convert a Pt100 resistance signal galvanically isolated into two identical or also into two different from each other galvanically isolated standarized output signals.


  • 12 different standard measurement ranges or adjustment by customer specification
  • Output 0..10V, 0..20mA or 4..20mA
  • Galvanic isolation with 4kV~
  • 20...253V AC / DC wide range supply

Function description

The Pt100 signal doubler WTAU 220-U0 is conceived for assembly on rail fastening acc. to DIN EN 50022 - 35. Due to the integrated wide input power supply for supply voltages from 20...253V AC and DC, the signal converter is suitable for using in all current international energy supply networks.

The activation of the device is signalled by a front sided integrated green LED. The Pt100 resistance signal is feed to the input of the signal converter and is transferred galvanically isolated to the both output stages.
