PR Electronics 9107B – HART Transparent Driver

Application

  • PR Electronics 9107B is a 1- or 2-channel isolated 1:1 driver barrier designed for intrinsic safety applications.
  • It controls I/P converters, valves, and indicators in hazardous areas.
  • It supports bi-directional transmission of HART communication signals.
  • PR Electronics 9107B can be installed in safe areas or in Zone 2 / Cl. 1, Div. 2 areas, transmitting signals to Zone 0, 1, 2, and Zone 20, 21, 22, including mining / Class I/II/III, Div. 1, Gr. A-G.

Features

  • The PR 45xx displays process values per channel and sets high and low limits for detecting loop current levels. The status relay activates if these limits are exceeded.
  • Dual channel versions can split signals (1 in, 2 out).

Advanced Features

  • The PR 45xx has a detachable display and green/red LEDs indicating operational status for each channel.
  • Each channel can be tagged.
  • Detects output line faults.
  • In the 1-channel version, the status relay can act as a simple limit switch.
  • Suitable for use in systems up to Performance Level “d” per ISO-13849.

Technical Characteristics

  • Provides high galvanic isolation of 2.6 kVAC.
  • High accuracy better than 0.1%.
  • Continuously checks vital stored data for safety.

Mounting

  • Can be mounted vertically or horizontally without spacing between adjacent units.
