Loop isolators provide signal protection by electrically isolating the input signal from the output. TxIsoLoop-1 and TxIsoLoop-2 simplify your application and avoid the 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, therefore no auxiliary power or an external power supply is needed!
