DC Signal Isolator, Passive

Signal isolator for electrically isolating an analog DC signal, and for converting it to a current signal or a voltage signal depending upon the utilized device variant. Functions as a passive isolator without external supply power and draws its minimal energy requirements from the DC signal.

  • Electrical isolation of the analog DC signal (0(4) to 20 mA): prevents the formation of parasitic voltages and currents and eliminates grounding problems with interconnected and intermeshed signal lines.
  • Highly accurate: fulfills the isolation function with practically no transmission errors.
  • No auxiliary power terminals: eliminates the need to lay and connect power supply lines, well suited for subsequent retrofitting to signal circuits.
  • Small and compact for optimized space utilization
  • N12 type rail mount housing for G rail per EN 50 035 – G32, or top-hat rail per EN 50 082
