XTR 11x application

Madhuri Akkenepalli

My customer is looking for help in the proper use of the XTR-11x for taking 0-5 VDC and converting to 4-20 mA for isolated and non-isolated 4-20 outputs.

 

 See graphic below... If does not show up open it up here....

What is the best XTR-11x product here? Here is the application circuit.

    Hello Madhuri,

    We're not 100% sure what you're trying to build based on the schematics and information you've provided so far. Are you showing two different options for the same system, or are the two schematics for two separate systems with separate design goals/requirements?

    Are you designing a 2-wire or 3-wire transmitter? If you're not sure, please let us know what the desired input and output connections for your design will be and we'll help guide you to the correct solution. I also recommend you take a look at the following series of blogs on 2-wire and 3-wire transmitters. They are all fairly short and provide a lot of good information on the design and debug of 2 and 3-wire 4-20mA transmitters:
