The 4–20mA current loop is the prevailing process control signal used in many industries. It is an ideal method of transferring process information because current does not change as it travels from ...

That output (V OUT) can directly drive external meters, strip-chart recorders, and A/D converter inputs. Figure 2. This circuit provides fault protection and digital-signal recovery for a 4-20mA ...

We are designing a circuit, which senses the analog DC current in the range of 4-20mA coming from field sensor. The accuracy level expected is 0.1%. Moreover the isolator should provide 2kV dielectric ...
