3186A2
- A2: 2 channel 2-wire transmitter isolator
- Isolation and 1:1 conversion of standard current signals
- Excellent accuracy, better than 0.05% of span
- Low voltage drop and fast response time < 5 ms
- Slimline 6.1 mm housing
Functional highlights
- 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.
- High 4-port isolation provides surge suppression that protects the control system from transients and noise and eliminates ground loops.
- The device can be mounted in Safe area or in Zone 2 / Division 2 areas and is approved for marine applications.
Technical highlights
- The device is powered by the host loop voltage.
- Excellent conversion accuracy, better than 0.05% in the range 3.8…20.5 mA.
- Fast response time < 5 ms.
- 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.
- NAMUR NE21, NE43.
- Excellent signal/noise ratio > 60 dB.
- High galvanic isolation of 2.5 kVAC.
- Inputs and outputs are floating and galvanically separated.
- Wide ambient temperature range: -25...+70°C.
Mounting / installation
- The narrow 6.1 mm housing allows up to 163 units per meter.
- DIN rail mounting with up to 326 channels per meter.
- Units can be mounted side by side, horizontally and vertically, without air gap on a standard DIN rail, even at 70°C ambient temperature.
