MVP 2023 Joe Tauser Posted August 12, 2023 MVP 2023 Report Share Posted August 12, 2023 Moved to the correct forum. For a 4-20 mA signal, do you have the jumpers set properly inside the module? If so, remove the input signal and measure the resistance between the input terminal and the COM terminal. It should be 500 ohms. I've been known to connect 24VDC directly to a 4/20 analog input and frying the resistor. Joe T. Quote Link to comment Share on other sites More sharing options...
