opto isolator
seems like you guys across the pond use the isolators alot...
Nelson Hobbies over here sell the S.M. services unit. I have been curious as to the reliability of the unit. I would love to have the advantages the unit has to offer but I am one of those people that have a firm belief that having the least # of parts in a system is reduces the chances of failure of that system.
Does anyone know or has anyone heard of any failures of the S.M. services unit??? And those of you who have had failures with any brand of isolator....what type of failures have you experienced??? complete unit failure, partial failure, etc.??
