PR 5105B Ex-isolated driver

PR 5105B Ex-isolated driver

Product Overview

  • 1- or 2-channel version
  • 3- / 5-port 3.75 kVAC galvanic isolation
  • Driver for Ex / I.S. area
  • 20 programmable measurement ranges
  • Universal supply by AC or DC



  • Safety barrier for current signals transmitted to I/P converters and displays mounted in hazardous area.
  • Safety barrier for analog current/voltage signals transmitted to hazardous area.
  • 1:1 or signal conversion of analog current/voltage signals.

Technical characteristics

  • The 20 factory-calibrated measurement ranges in the 5105B can be selected by the internal DIP-switches without the need for a recalibration. Special measurement ranges can be delivered.
  • PR5105B 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.

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.
