    Wayne,

    Can you list a BOM for what is shown there? I realize it may not be current, and these are always changing, but I am trying to figure out what is what, and that would certainly help me.

    Thanks.

    Are SSRs "on/off", or can they function as dimmers?

    Thanks, I've searched the forums 9 ways to Sunday, forgot about the Wiki - and that's where the answer was.

    No problem, I always try to remember "the wiki is your friend"


    Now if we can just get Frank to write a wiki on the DMX/Renard....

    Here's a quick follow-up on my SSR question. I posted a similar question at http://diylightanimation.com/, one of the admins offered a few more details:

    In a basic way all SSR are On/Off at there core. Some are not dimmable as they are what is called zero cross triggered.

    This means they can only be switched on or off at the point in an AC cycle where the voltage goes to zero (ZC .. Zero Cross) . These can not be dimmed but can turn power on and off.

    Random triggered SSR's (what we build here) can be turned on at any point in the AC cycle but will only turn off at the ZC.

    With these points in mind here is how dimming works with random triggered SSR's and a standard dimmer.

    The SSR is triggered at some point in the cycle. IT can be at the very beginning in which we trigger it and it will then stay on the whole cycle till it turns off at the end ZC ( remember it only will turn off at this point no matter what once it is turned on). This would give us 100% power 100% of the time for full on.

    Or we could wait till half way throught the cycle and it would give us 100% of the power 50% of the time for an average of 50% of the energy to the light. This will dim the light.

    We could never trigger it and it would give us 100% of the power for 0% of the time and the light will not come on.

    This is a basic description and there is a little more to it. But in simple terms this is what happens.

    The zero cross triggered SSR will only turn on at ZC and off at the next one so it is either 100% of the time or 0% of the time so you end up with on or off.
    Hope this helps others as much as it helped me.

    Hi there, sorry but I'm still confused on how to wire it up.
    I've attached a pic. of how I think it should go. Would you
    please tell me if this is correct.

    Correct!! You might even place that excellent illustration into the Wiki.
