Isolator without auxiliary power RH1022

The loop-powered isolator RH 1022 electrically isolates 0(4) ... 20mA standard signal circuits and transmits the measurement signal to the output with high accuracy. It thus avoids interference voltages being carried over and effectively suppresses interference. Due to the low internal voltage requirement of only 2.0 V, the high level of accuracy and the compact design, the RH 1000 is the first choice in plant construction.

Intelligent circuit technology and the consistent omission of highly integrated circuit components leads to an extremely long service life and reliability without falsification of the measurement signal.
