Resistor / analog converter WZ102
converts ohmic resistance or potentiometer into analog output signal,
galvanic 3-way isolation
- Converts a variable resistance into an analog output signal
- Input ranges two-wire: 0-300 / 500 / 1000 Ohm
- Three-wire input ranges: 100 Ohm to 1 MOhm
- Output ranges 0/4 mA to 20 mA, 0/1 VDC to 5 VDC and 0/2 VDC to 10 VDC
- 19 VAC to 28 VAC- / 19 VDC to 40 VDC- Power supply
- 3-fold galvanic isolation supply/input/output

The WZ102000 resistor/analog converter converts an ohmic resistor from 0 to 1 KOhm or a potentiometer from 100 Ohm to 1MOhm into an analog output signal from 0/1 VDC to 5 VDC, 0/2VDC to 10 VDC or 0/4 mA to 20 mA. The device is easy to program with its DIP switches. The device is simply snapped onto the top-hat rail for installation.
