3185A1
- 1 channel input loop-powered isolator
- Isolation and 1:1 conversion of standard current signals
- Excellent accuracy and high load stability
- Low input voltage drop and fast response time
- Slimline 6.1 mm housing
Functional highlights
- 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
- Low input voltage drop, typ. 1.35 V + Vout
- Excellent conversion accuracy, better than 0.1% in the range 0…20.5 mA.
- Fast response time < 5 ms.
- NAMUR NE21, NE43.
- Excellent signal/noise ratio > 60 dB.
- High galvanic isolation of 2.5 kVAC.
- Inputs and outputs are floating and galvanically separated.
- The output is voltage limited to 17.5 VDC.
- 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.
