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.
Features:
- No need for power supply
- Powered from the input loop
