[FAQ] Why does my 2-wire 4-20mA transmitter output not reach the full 20mA?
Resolved
Why does my 2-wire 4-20mA transmitter output not reach the full 20mA? When I change the load resistance or decrease the supply, the output changes. What can I do to fix this?

RE: AMC1311-Q1: AMC1311
Hi Sunil, I was hoping to get more time with this but, one thought I had would be to try and use something like an
XTR112
or XTR114 to try and realize what it is that you want to do here. My thinking was that you could use the differential output of...

RE: [FAQ] What is a 2-wire 4-20mA current transmitter?
2-wire transmitters are loop powered devices most commonly used to monitor a remote process with no access to a local supply. Two analog signal wires carry both the analog output signal, and power for the sensor/monitoring circuitry and transmitter. The...

[FAQ] Can I use a 2-wire 4-20mA transmitter with a sensor or microcontroller that uses its own supply?
Resolved
2-wire 4-20mA transmitters are loop powered, and the sensor and its associated circuitry are supplied by the transmitter. Is it possible to use a sensor or microcontroller that uses a separate supply as the input to my 2-wire transmitter?
