Kim Posted December 2, 2007 Share Posted December 2, 2007 It seems i have a bad opto MOC3023 on channel 8!I cant find them here in Denmark!I bought a MOC3063 which should be compatible (Just rated for higher voltage) but it dont work either!All voltages around the opto is fine compared to a working channel! (Except for signal to R7 when the channel should lit)Is there a equivalent to the MOC3023 i can use?Regards/Kim Link to comment Share on other sites More sharing options...
AI Posted December 2, 2007 Share Posted December 2, 2007 I bought a MOC3063 which should be compatible (Just rated for higher voltage)You my need to change the gate resistor. AI Link to comment Share on other sites More sharing options...
Kim Posted December 2, 2007 Author Share Posted December 2, 2007 Resistor measures 330 ohm (Im using 230v) so its ok.I just compared the 3023 and 3063 and it seems i got wrong information about compatibility. The 3063 has a zero crossing circuit wich the 3023 dosnt have.Wish i had a cross reference guide /Kim Link to comment Share on other sites More sharing options...
AI Posted December 2, 2007 Share Posted December 2, 2007 Yes it is vary hard to fine the optos without the 0cross. Some times you can find them on E-Bay. If you can't find them let me know I have some. AI Link to comment Share on other sites More sharing options...
