for several I/O circuits rated at less than 30V but with an isolation rating of 250 V, what is the spacing requirements between isolated i/o's? That is say you have two i/o circuits, extra low voltage, but in the specs say they are isolated, 250V. If you're using IEC 1010 do you use the 50 V spacings from the tables or use the 300 V spacings from the tables for spacing between the two circuits?
thanks for any input eric [email protected] ps - my opinion is use the 300 V spacings.
