Is it possible to convert a two-wire loop-powered 4-20mA transmitter's signal to Foundation Fieldbus? I also have access to a HART/FF converter, and was wondering whether the 4-20mA signal without a digital signal superimposed on it can be converted by it? The transmitter in question is a GE oxy.IQ Panametrics Oxygen Transmitter, and it needs to interface to a Foundation Fieldbus system.

 

There's this Smar product: https://www.smar.com/en/product/if3...el-current-to-foundationtm-fieldbus-converter

"The IF302 receives a current signal, typically 4-20 mA or 0-20mA, and makes it available to the Fieldbus system."
