  • 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.
