WebDec 24, 2024 · If the output terminal is working, then you should measure 0 volts when ‘OFF’ and the full source voltage when ‘ON’. For digital and relay outputs, this is true. It should also be true for AC outputs driven by TRIACs, but in these cases, some confusing meter readings can … Webcurves of a typical TRIAC. Note that the snapback voltage decreases as the gate current increases from an initial zero point value. Fig. 8 - TRIAC Finally, a phototriac can be …
WebDec 30, 2011 · Location St. Louis, MO. Posted December 29, 2011. Have VOM or now days a DVM, will troubleshoot. Take a ohm meter and read the ohm across the A1 and A2 leads. Then reverse the meter leads. If in either test the resistance is below say 1K ohms the Traic is considered shorted. Mind you, a few volts DC is not the same as 120VAC. WebSep 13, 2024 · Simple way to test a triac under power is use a 6v - 12v transformer and hook a suitable lamp and the triac up in series across the secondary, use a 33ohm resistor from G to A2 and it should switch on/off with when resistor connected.
