These Loop isolators provide signal protection by electrically isolating the input signal from the output. They 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.
