4-20Ma Current Loop Receivers Connectivity Issue


Hi I wanted to read the signals of multiple Sensor with the help of two 4-20mA current loop receiver with same address
But while interfacing the sensors with raspberry pi using both current loop receivers and checking the address for I2C connectivity in command line, I am not able to find out the connectivity of only one current loop receiver
But when I am checking the loop receivers individually (one at a time) both are working fine
what could cause this??
Your Suggestion will be helpful to me
