PR Electronics 5106B – HART Transparent Repeater

Application

  • PR Electronics PR5106B is designed for use as a power supply and Ex/IS safety barrier with two-way HART communication for 2-wire transmitters in hazardous areas.
  • It also serves as an Ex/IS safety barrier with two-way HART communication for current-supplied transmitters installed in hazardous areas.
  • Additionally, it functions as a signal isolator with rapid response times for analog current signals from hazardous areas.

Technical Specifications

  • PR Electronics PR5106B primarily handles current signals ranging from 4 to 20 mA.
  • It utilizes microprocessor technology for precise adjustment of gain and offset. The analog signal is transmitted with a response time of under 25 ms.
  • Inputs, outputs, and power supply are isolated and galvanically separated.
  • The output can be configured for use as either an active current transmitter or a 2-wire transmitter.

Mounting/Installation

  • It can be mounted vertically or horizontally on a DIN rail. Units can be placed without spacing between neighboring units, allowing for up to 84 channels per meter.
  • PR Electronics PR5106B is recommended as an Ex/IS safety barrier for models 5335D and 6335D.
