Pt100 signal converter, active; free adjustable, for conversion from Pt100 to 0/4-20mA or 0-10V

WTAU-100-U0 - picture Pt100 signal converter, active; free adjustable, for conversion from Pt100 to 0/4-20mA or 0-10V


  • Input from -100°C ... +600°C, free adjustable
  • Output 0..10V and simultaneous 0..20mA or 2..10V and simultaneous 4..20mA
  • Galvanic isolation with 4kV~
  • Signal adjustment of zero and span
  • 20...253V AC / DC wide range supply

Application description

The Pt100 signal converter WTAU 100-U0 is used to convert a Pt100 resistance signal galvanically isolated into a standarized signal and to adjust is in the zero value and/or span.

Function description

The Pt100 signal converter WTAU 100-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. Inside the housing the different input and output signals can be set by dip switches in arbitrary combinations. The Pt100 resistance signal is feed to the input of the signal converter and is transferred galvanically isolated to the output stage. The temperature range is preselected in zero and span by the dip switches and can than be fine adjusted by the front sided trimming potentiometer at zero in the range from -100K...+35K and at span in the range from 25K...660K.
