RBC Posted September 25, 2019 Report Share Posted September 25, 2019 Hi. Hope someone can help. I've got 2 analog input cards in my system. All configured the same. The one card my temp is stable but the 2nd card the reading fluctuates a lot. from 1 to 35 to 17 and so on. Connected pt100 connected to convertor to 4-20ma directly in panel to see is cable fault. Still the same. Any ideas please. Thanks. Quote Link to comment Share on other sites More sharing options...
