Brand: PR Electronics
Request a Quote
  • 1 or 2 channel 2-wire transmitter isolator / current isolator
  • 1:1 conversion in the range 3.5...23 mA
  • Low channel voltage drop and fast response time < 5 ms
  • Excellent accuracy, better than 0.05%
  • Slimline 6 mm housing
Features
  • 3186 is powered by the host loop voltage.
  • 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.
  • Excellent conversion accuracy, better than 0.05% in the range 3.8…20.5 mA.
  • Signal range is 3.5...23 mA which means that 3186 is NAMUR NE43 compliant.
  • Inputs and outputs are floating and galvanically separated.
  • High galvanic isolation of 2.5 kVAC.
  • Fast response time < 5 ms.
  • Excellent signal/noise ratio > 60 dB.

Applications

  • 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.
  • A very competitive choice in terms of both price and technology for galvanic isolation.
  • Provides surge suppression and protects control systems from transients and noise.
  • 3186 eliminates ground loops and can be used for measuring floating signals.
  • The device can be mounted in Safe area or in Zone 2 and Cl. 1 Div 2. area.
