RicksinSD Posted December 1, 2014 Report Share Posted December 1, 2014 Good morning to all, I'm I&C tech here at my plant, and we have been having problems with these modules, so far 3 modules have been needed to be replaced. The issue with them, is that some of the output channels do not change state even when the status LED does. we have removed power to the module in order to "reboot""reset" and they start working again, but as time goes by,they go bad again. Could our problem be external to the modules? Our set up is: HACH sequencer>EX-A1>IO-DI8-R04>IO-AI4-AO2>IO-AO6X The loads for the DI8-R04 are 120vAC solenoids and they do not have the RC snubber, if we need to have them, any recommendations on which to buy/use? Thanks. Quote Link to comment Share on other sites More sharing options...
