9180 series Ex i resistance isolators can be used for the intrinsically safe operation of Pt100 or Pt1000 resistance temperature detectors. The resistance measured at the input is transmitted to the output and can thereby be measured by an I/O card. The auxiliary power, output and intrinsically safe input are galvanically separated.
- Ex i resistance isolator for Pt100 or Pt1000
- world's only two-channel device requiring just 8.8 mm of space per channel
- for two-, three- and four-conductor connection
