    Default Which DCSSR to get? Dumb RBG strip.

    Greetings

    I have 2 feet of dumb rgb strips in my North pole for lighting.

    +12v
    B
    R
    G

    is the wiring layout.

    +12vdc is COMMON and the ground wires run independent for each colour, THIS IS OPPOSITE to how a typical SSR is built where ground is COMMON.

    Not pixel strips, just dumb 12vdc 5050 leds with resistors..

    Which DC SSR should I be looking to buy?
    Cheers!

    No - - the typical DCSSR is common anode (common +) and the MOSFETs sink the ground from each color.

    So on a DC SSR like this, would you run a jumper wire from the + out to the other + outs and then connect the R,G, and B to the - outs.

    I have to admit I'm a little confused about this as well.

    I'm not completely familiar with the DirkCheap SSR but I think you'll find it's the same as the DCSSR and the input +DC is the same connection/trace as the + on the RGB outputs and are already connected together. A quick look at it visually and/or with a meter should tell you that.

    You'd provide +/- power at the DC IN terminal block. Then you have four channels of output, and the + signal is common to all four channels while the - is switched. You would want to use common anode strips with this SSR.

    Even though the DIGWDF Store has been closed for more than a year, it's still awesome!
    User guides, documentation and other files are still free and available for downloading.

    In answer to the OP's question. I would recommend one Dirk's Cheap DC SSR's like shown above. You can get them @ http://digwdf.com/store/category.php?id_category=9 . He has two different versions available, one is capable of handling higher amperage.
    2012 - 1st year 64 Channels - 7500 LED lights - 5 sequences
    2013 - 128 Channels - 10,000 LED lights - 7 sequences (2 New)
    2014 - 201 Channels - upgrading 8 Arches to dumb RGB - 8+ sequences (1+ New)
    2015 - 240 Channels + 8 Universes - sequences TBD
    2016 - No Display
    2017 - Back in the Game - 240 Renard Channels + 12 Universes
    2018 - 256 Renard and 9 Falcon Outputs of Pixels - 16 sequences shown over 2 nights

    Would a DM-103 work, you could embed this into your prop (they are very tiny).

    I believe RobG has alternative firmware for this tiny board as well (to run some DMX floodlights).
    I bought 10 on my last order from Ray, but doubt I am going to use them all this year.

    Budude, on closer examination of my DC SSR, you are correct! re-wiring my connection and testing..

    Edit**
    Forgot to reply after testing..

    Everything is working.. I had my SISO board incorrectly wired to my Ren8SS
