Just wondering what the advantage of a relay is apart from perhaps isolation?
Why would you ever bother with a bulky relay that has mechanical wear and requires more power to activate?
I need to take a logic level output from a gate motor controller and use it to switch on some 12V AC garden lights when the gate opens. I initially thought I needed a relay but wonder why I wouldn't just use a TRIAC?
TIA,
JohnO
