Loop isolators provide signal protection by electrically isolating the input signal from the output.
TxIsoLoop-1 and TxIsoLoop-2 simplify your application and avoid the undesirable ground loops by providing single and dual loop galvanic isolation. The 0/4-20 mA input is measured and an identical isolated signal is reproduced at the output.  Power is drawn from the 0(4)-20 mA input loop, thus no auxiliary power or an external power supply is need.


      
  • Input Signal (INPUT): 0 to 20 mA; 4 to 20 mA (check minimum current for proper operation)

    •   
  • Maximum Input voltage (Vin max.): 32 Vdc

    •   
  • Voltage Drop (Vdrop): < 3 Vdc

    •   
  • Output Signal (OUTPUT): 0(4) to 20 mA

    •   
  • Max. Load (RL): 1450 R

    •   
  • Accuracy: 0.2 % FS @ 0 a 60 °C / RL= 250 R; 0.3 % FS @ -20 a 75 °C / RL= 250 R

    •   
  • Operating current: > 0.1 mA

    •   
  • Overload: < 40 mA; < 32 Vdc

    •   
  • Response time: 2 ms @ RL= 250 R

    •   
  • Isolation: 3000 Vac / 10 s; 240 Vac continuous

    •   
  • EMC:  EN 61326-1

    •   
  • Ambient temperature range: -20 to + 75 °C

    •

    •   
  • Protection: IP40

    •   
  • Wire gauge for connections: 0.14 to 1.5 mm²

    •   
  • Recommended torque: 0.8 Nm

    •   
  • Terminal blocks injected in Polyamide
