Loop-powered isolating repeater Series 9167

Loop-powered isolating repeater Series 9167

The Series 9167 Ex i isolating repeaters for field circuits operate without auxiliary power and can be used for the intrinsically safe operation of control valves, I/P converters, analogue indicators and fire or gas detectors, for example. The devices have one or two channels and transmit HART signals (0/4 to 20 mA) via the analogue output. The devices transmit superimposed HART communication signals in both directions.

  • Compact loop-powered one- and two-channel Ex i output isolating repeater
  • Suitable for fire and gas detectors
  • For use up to SIL 3 (IEC 61508)
