תיאור
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.
Variants:
IRU – 420 – I – convert's signal 0/4 ÷ 20 mA to 0/4 ÷ 20 mA
IRU – 420 – H – convert's signal 4 ÷ 20 mA to 4 ÷ 20 mA and bi-directional transmission of HART® communication signal
IRU – 420 – U – convert's signal 4 ÷ 20 mA to 0 ÷ 10V
