Please, are there any standards or guidance prefer to segregate between analogue signal in & out of the same level ( level-1).

As far as I know the segregation between Digital and analogue signals and separate between ESD DCS signals too. but to segregate between the IN & OUT of the same signal type used for the same control system, I have no reason to do so even my consultant insist for me to apply his idea to segregate between IN & OUT digital and analogue.

Many Thanks

From the information provided, you are correct.

Unless there is a compelling reason we are unaware of there would be no difference between input and outputs of the level.

 

Thanks for your reply
