PR electronics, 3186B2, 2-wire current isolator

Features

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

Application

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.

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.

Mounting / installation

DIN rail mounting with up to 330 channels per meter.
Extended operating temperature range from -25...+70°C.
