I have a triac coupled to a random phase opto-coupler. Even when there is no low side voltage signal to the opto the triac is showing an output of 16vac. The triac is coupled to a 240vac mains voltage. This low voltage would not be able to operate a mains device.
Is this normal for a triac. What would be the explanation for my meter showing this voltage?
