PR 9106A HART Transparent Repeater

  • 24 VDC supply via power rail or connectors
  • Active and passive mA input
  • Active or passive output via the same two terminals
  • Splitter function – 1 in and 2 out
  • SIL2 / SIL3 Full Assessment and certified acc. to IEC 61508


  • 9106A is a 1- or 2-channel isolated 1:1 repeater.
  • The device supplies 2-wire SMART transmitters and can also be used for 2-wire SMART current sources. HART & BRAIN protocols are supported and are transferred bi-directionally.
  • 9106A can be mounted in the safe area or in zone 2 / Class I, Division 2, Groups A, B, C, D.
  • For duplication / migration purposes, the outputs can be sent to two different DCS / PLC / HMI or any monitoring system.
  • In safety applications (SIL loops), the 9106AxBx can be used as a splitter with the following output configuration:
  • When using 9106AxBx in a SIL2 safety function, channel 1 is used for the safety loop. Channel 2 can be used for any non-safety device.
  • For higher safety purposes (SIL 3), 9106AxBx can be used as a splitter for SIL 3 loops. Channel 1 and 2 are then connected to the same safety PLC, where channel 2 is used as a redundant diagnostic channel (for more information, consult the FMEDA Report and the Safety Manual).

Advanced features

  • The detachable display 45xx and the green and red front LEDs indicate operation status for each channel.
  • Monitoring of error events and cable breakage on input via the individual status relay and/or a collective electronic signal via the power rail.
  • Suitable for the use in systems up to Performance Level “d” according to ISO-13849.

Technical characteristics

  • High galvanic isolation of 2.6 kVAC.
  • Fast response time <5 ms
  • High accuracy better than 0.1%.
  • 2-wire transmitter supply >16 V.


  • The devices can be mounted vertically or horizontally without distance between neighboring units.
