PR Electronics – 3103 Isolated Repeater

A signal isolator or signal converter is a signal conditioning device used to interface process signals with other devices. Signal isolators ensure a stable and accurate signal output by offering superior resistance to electro-magnetic interference. They are also capable of converting and amplifying the process signals for improved performance and compatibility. PR electronics offers a range of isolators with superior performance and low power consumption.



  • Isolation and 1:1 conversion of standard current signals.
  • Galvanic separation of analog current signals.
  • Elimination of ground loops and measurement of floating signals.
  • A competitive choice in terms of both price and technology for galvanic isolation of current signals to SCADA systems or PLC equipment.
  • Installation in ATEX Ex zone 2 / IECEx Zone 2 / FM division 2.
  • Suitable for environments with high vibration stress, e.g. ships.

Technical characteristics

  • The input is protected against overvoltage and polarity error.
  • Factory-calibrated measurement ranges.
  • Inputs and outputs are floating and galvanically separated.
