So I need a last word of wisdom.
Following advices given in my other thread I've bought opto-triacs to trigger the power-triacs.
Are my resistors reasonable sized?
What to use to see if power-triac is properly triggered by opto-triac?
Would a LED work if i place diodes at both ends of it to prevent voltage going reverse direction?
To look at the AC-signal in a scope, can I connect a diode to one of the lines to make it work as GND for the scope? I just want to see it coming on and off? IIRC I used this method when I wanted to see if the zero-crossing detection code I wrote was working? (There is no need for ZCD in this application). Just want to see that AC is flowing through triac.
Other considerations before I finally hook the 24VAC motor up?
I have a varistor connected between AC-lines to suppress current-rush.
Attached is datasheets for triacs and the circuit I intend to use.
