Hi,
I need to interface 4 to 20mA Digital Transmitter Board(attached datasheet) with MCU. I am new to HART type communication. I need some information that how i can interface this sensor board with MCU.
Thanks

Does this help?

I don't suggest connecting a 4-20mA loop directly to the MCU A/D converter.

Hi Keith Barkley

Yes, i agreed.
Here is the more detail of the transmitter.

I wonder if i can use this converter instead of resistor.

Thanks

That would be great, especially if it provides ground isolation from the MCU to the current loop.
