  1. Overview

  2. Technical details

  3. Accessories


Application

  • Power supply and signal isolator with 2-way HART communication for 2-wire transmitters installed in the hazardous area.
  • Signal isolator with 2-way HART communication for supplied current transmitters installed in the hazardous area.
  • Signal isolator with low response time on analog current signals.

Technical characteristics

  • PR5106A primarily processes current signals of 4...20 mA.
  • PR5106A 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 transmitter or as a 2-wire transmitter.

Mounting / installation

  • Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without distance between neighboring units, up to 84 channels can be mounted per meter.
