Read up on 4-20mA current loop. Industry standard or prefered method. Didn’t know that.
When I posted, the thought was in the back of my mind, ‘probably will not matter due to it be a current loop’.
Thanks for confirming Bob.
Cheers

Hi Jim
Not sure but I think 4 - 20mA loop is a pretty robust system in “dirty” environments.
