How can I split a 2 wires 4-20ma signal of a pressure sensor to be read by 2 AI devices of 2 separate PLCs without using 2-channels splitter isolator? What happen to signal that change my reading according to parallel or series connection to sensor?
If I cannot connect 2 AI devices to the sensor, what is best method? Please provide a suggestion.
Thanks
