I am using a DL250 Koyo PLC and I use a F2-04RTD analog RTD input module to receive signals from 6 RTD's. The reading of the 4 RTD's are all OK but the reading of the other 2 RTD's is fluctuating. I add a filter thru PLC Ladder logic but the reading for the 2 RTD's is still fluctuating. The reading must be more or less 40 deg. Celcius but the reading fluctuates from 19 to 75 deg. Celcius. Someone help me solve this problem??? I want to place an electrolytic capacitor across CH+ and CH- terminals of the module to filter the input from the RTD.Any advice please
