Application
1:1 output loop powered isolator of 2-wire transmitter 4...20 mA signals.
3186 is an easy mounting DIN rail unit.
A very competitive choice in terms of both price and technology for galvanic isolation of 2-wire transmitter signals.
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.
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.
Excellent conversion accuracy, better than 0.05% in the range 3.8...20.5 mA.
Functional 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.
Mounting / installation / programming
DIN rail mounting with up to 330 channels per meter.
Temperature operation range is from -25...+70°C.
