Hello,
Does anyone know of a device or method to measure a 4-20mA signal then superimpose the value of this signal via HART on a second 4-20mA loop?
This would basically be the opposite of what a Rosemount Tri-Loop does.
I have a field device that has two 4-20mA outputs for process variables, but only 1 twisted pair cable back to the IO. I'd like to superimpose one of the process variables on the 4-20mA of the other variable, then use a Tri-Loop 333 to split them again in the IO cabinet.
Thank you,
j_dubya
