IRU-420 Atex Isolating repeater


 Features

  • universal intrinsically safe isolating repeater of current signals 0/4 ÷ 20 mA with 0,07 % accuracy and with option voltage output 0 ÷ 10 V
  • galvanic separation input and output signal
  • for supply sensors with output 0/4 ÷ 20 mA e.g. CLM-36Xi, ULM-55Xi etc. in explosive area up to zone 0 (acc. to EN 60079-10)
  • option bi-directional transmission of communication signal HART®
  • classifi cation of explosive-proof performance
    • EEX II (1)G [EEx ia] IIB / IIC
    • EEX  I (M1) [EEx ia] I
  • instalation on DIN rail 35 mm
  • variants for 24V and 230V


Universal intrinsically safe isolating repeater IRU-420 is designed for supply transducers of physical value (sensors) in explosive areas and for conversion of input signal 0/4 ÷ 20 mA to output signal. Galvanic separation of current signal 0/4 ÷ 20 mA from transducer in explosive area to transducer in non-explosive area.
