Thiim AITA Triple Loop Isolator 4…20mA


  • 3 Loop isolators 4…20mA in one unit
  • Prevent lightning from spreading over the system
  • Working voltage max.: 1000VRMS
  • Transient overvoltage max.: 8000Vpeak
  • Excellent linearity
  • Small outlines, 35mm. wide


The loop isolator is designed to separate a 4…20mA loop into two galvanically separated 4…20mA loops in order to prevent signal distortion and instrumentation damages due to electrical noise or voltage spikes and ground loop currents. The insulation is based on a high performance linear optocoupler with an excellent linearity and a low coupling capacitance.

For use in instrumentation with current loop I/O as used by PLCs, sensors, recorders, indicators, alarm units etc.

  • 4…20mA Max. input 100mA
  • Loop supplied Voltage drop, Max. 7V
Performance Parameters
  • Response time < 10msec.
  • Precision Class 0.5 according to DIN / EN60688
  • Linearity < 0.02 %
  • Temp. dependence ±0.02% / °C
  • Supply dependence ±0.01% / %
  • ∆U
  • Loop supplied Loop voltage , 8…32V
  • 4…20mA Max. voltage, 36V
