3185A2
- 2: 2 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.
PR 3185A2 technical documentation
Original manufacturer documents in English:
- PR 3185 data sheet (PDF, EN)
- PR 3185 manual, 3185V104-EN (PDF, EN)
- Official PR 3185 page: documentation and previous versions
The 3185 family documentation includes the two-channel 3185A2 variant. Manual 3185V104-EN is specified for devices from serial number 221046149. Check your device's serial number; for older units, consult the corresponding version on the manufacturer's page.
Is PR 3185A2 suitable for my 4–20 mA loop?
PR 3185A2 is powered from the input loop. Before ordering, check the transmitter and PLC input wiring, available voltage and output load. The required input voltage includes the isolator's own voltage drop and the voltage across the output load. Check the entire loop voltage budget, including the transmitter's requirements and cable losses.
To check compatibility, contact ATSEN and provide the transmitter and PLC module codes, wiring diagram, supply voltage and load. Consult the wiring and limits in the PR documentation matching the device version.
