Davenj Posted May 8, 2019 Report Share Posted May 8, 2019 We currently have V130's that are 12vdc. I want to measure temperature and one more analog input. Which expansion, and adapter modules would be best suited. Thanks in advance for the help. Dave Quote Link to comment Share on other sites More sharing options...

MVP 2021 Ausman Posted May 9, 2019 MVP 2021 Report Share Posted May 9, 2019 I hate to be contrary here, but doesn't the AI4AO2 only work on 24v? In the long dim past I remember getting into trouble trying to do a fully 12v system with a mix, as some of the I/Os would only work on 24, not 12. cheers, Aus Quote Link to comment Share on other sites More sharing options...
DanT Posted May 10, 2019 Report Share Posted May 10, 2019 Hi; Ausman : Correct - looked at the Spec Sheet for the IO-AI4-AO2, Power is 24 VDC ( 20.4 - 28.8V Range). -- needed for the Analog Outputs IO-ATC8 -- does not have an external Power Supply Requirement, all terminals dedicated to Inputs IO-PT400 - - does not have an external Power Supply Requirement, all terminals dedicated to Inputs Soooo -- these are dependent on power from the Bus, and are NOT Isolated !!
