trouble with a triac

(1/4) > >>

1makermold:
I am having a problem with a triac BAT16, when I trigger it with an optocoulpler it turns on but the voltage is half of what it should be, Im trying to make a switch for 12 to 24 vac, I have tried a Q4006l triac but still have the same results

soldar:
I do not understand what you are trying to do. Can you post a schematic?

1makermold:
Here is the schematic, I figured it out last night I changed the 150 ohm resistor to 100 ohms works good now, thanks,
but I was wondering if I could trigger the gate with a transistor other than a optocoupler, or would it latch and just stay on

soldar:
The text of your OP makes no sense with that circuit.

You cannot use a bipolar transistor to control the triac because the switching voltage and current reverse direction.

1makermold:
I know, on the schematic it says 240 volts but I'm only using 24 vac, thanks
