Functional highlights

  • 3186A is a 1:1 output loop-powered 2-wire transmitter isolator that excites and measures passive input signals.
  • 3186B is a 1:1 output loop-powered 2-wire current isolator that measures active input signals.
  • High 4-port isolation provides surge suppression that protects the control system from transients and noise and eliminates ground loops.
  • The device can be mounted in Safe area or in Zone 2 / Division 2 areas and is approved for marine applications. 

Technical highlights

  • The device is powered by the host loop voltage.
  • Excellent conversion accuracy, better than 0.05% in the range 3.8…20.5 mA.
  • Fast response time < 5 ms.
  • Wide supply range from 6...35 V.
  • Low input to output voltage drop typ. 2.5 V (3186A).
  • Low input drop ≤ 3 V (3186B), even when no loop power is applied to the output terminals.
  • NAMUR NE21, NE43.
  • Excellent signal/noise ratio > 60 dB.
  • High galvanic isolation of 2.5 kVAC.
  • Inputs and outputs are floating and galvanically separated.
  • Wide ambient temperature range: -25...+70°C. 

Mounting / installation

  • The narrow 6.1 mm housing allows up to 163 units per meter.
  • DIN rail mounting with up to 326 channels per meter.
  • Units can be mounted side by side, horizontally and vertically, without air gap on a standard DIN rail, even at 70°C ambient temperature.
