Guest guest Posted October 24, 2006 Share Posted October 24, 2006 Looking at areas U6 all the way to U21 there should be 16 6 pinned chips (Opto isolators I believe) Only problem is 13 match codes on top of the chip and the other 3 dont.....13 x M0C30233 x MDC3023Is there any difference?

Guest guest Posted October 24, 2006 Share Posted October 24, 2006 There are possibly the same but from 2 different suppliers. I don't think it is a problem. You might want to send an email to info@lightorama.com to confirm.Yves Link to comment Share on other sites More sharing options...
Guest guest Posted October 24, 2006 Share Posted October 24, 2006 In two of my kits all of the optos matched in one kit they did not. This did not affect the funtion in any way. Link to comment Share on other sites More sharing options...

Then it is most likely a Triac output optoisolator and won't cause you any problems, as long as you install it in the correct direction. Link to comment Share on other sites More sharing options...
Guest guest Posted October 25, 2006 Share Posted October 25, 2006 Thanks guys :-) Another question before I proceed to test, do I have to ground the heatsinks?I have the bigger high power ones.Thanks Link to comment Share on other sites More sharing options...
Guest guest Posted October 25, 2006 Share Posted October 25, 2006 You don't have to ground them. It's just a nice place to land the ground if you are going to use grounded plugs and pigtails. I have two styles of boards, and mounted them in different ways. On the large heatsink style I ran a #12 wire from sink to sink (all my boards but one are in a large metal case) on the 2 kit boards I have, there are low power heat sinks. I didn't ground them at all.On my Orbit box, I crimped a lug on the green ground wire and landed it on a mounting screw that mounts the large heatsink. None of the output extension cords have a ground.If you're using a metal case to mount your boards, you it's necessary to ground the case.jeff Link to comment Share on other sites More sharing options...
