I have a 4-20 mA loop that runs parallel to a 230 kV power line for less than a kilometer and the analog input on the PLC keeps getting smoked. There was a surge suppressor on it but no isolation.
Can anyone recommend an isolator that will provide +24 out to the sensor and provide isolated 4-20 to the PLC?
