PR electronics 3186 2-wire transmitter isolator/ current isolator. 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. 1 or 2 channel 2-wire transmitter isolator / current isolator. 1:1 conversion in the range 3.5...23 mA. Slimline 6 mm housing.
Technical characteristics
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.
