PR 5104B Ex repeater / power supply

  • 1- or 2-channel version
  • 3- / 5-port 3.75 kVAC galvanic isolation
  • Loop supply > 17.1 V in hazardous area
  • 20 programmable measurement ranges
  • Universal supply by AC or DC


  • Supply voltage and safety barrier for 2-wire transmitters mounted in a hazardous area.
  • Safety barrier for analog current/voltage signals from a hazardous area.
  • 1: 1 or signal conversion of analog current/voltage signals.

Technical characteristics

  • The 20 factory-calibrated measurement ranges in the 5104B can be selected by the internal DIP-switches without the need for recalibration. Special measurement ranges can be delivered.
  • PR5104B is based on microprocessor technology for gain and offset. The analog signal is transmitted at a response time of less than 25 ms.
  • Inputs, outputs, and supply are floating and galvanically separated.
  • The output can be connected either as an active current/voltage transmitter or as a 2-wire transmitter.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. By way of the 2-channel version, up to 84 channels per meter can be mounted.
  • NB: 5104B is recommended as I.S. barrier for 5331D, 5333D, 5334B, 5343B, 6331B, 6333B, and 6334B.
