    Default Not fadeing

    So got a 8 ch ssr. I was told some where that I'd be able to fade lights with it. So far it only turns on and then off. Any ideas? I could be wrong about the fading part

    What type of SSR? What type of controller?


    2019 - Just moved into a new home (yet another change of plans). Will be dim but not dark. Too much to do at the new place to leave time for a show.

    It's a low level eight channel relay and I'm running it with vixen on falcon pi player
    This is the link for the relay I bought

    That relay needs an additional controller to drive it. FYI: That relay has a built in Zero Cross circuit. This means you cannot (easily) use it for dimming. It is an on/off type of device designed to be driven by an arduino type device.

    It worked fine when I used the gpio pins it just won't dim. So if I got a non zero cross would I be able to do dimming through the gpio pins

    Yes you would. Then you could send out a timed pulse to trigger the SSR at various parts of the AC cycle so you get almost any brightness you like. NOTE: I suggest you look into a controller that knows how to do dimming. You can get a list of them on the wiki. My favorite is the Renard series of controllers.

    Looks like they are zero-cross Solid State Relays, so they won't dim/fade. Just on/off

    So I'd need to get one that can cross

    Yes, non zero cross or random cross.

    Very brief explaination...
    The Solid State Relays (actually the opto-isolators in them) come in zero-cross and random-cross. Zero-cross means it only activates the Traic when the AC voltage is zero. This keeps the voltage AC wave from being chopped and is advantageous when noise on the circuit could cause problems. Random-cross will turn the Triac on at anytime and will allow a partial wave, this is how we dim the circuit, turn it on for a portion of the AC voltage wave and off again at the next zero.

    Hi, so you don't end up with an item that doesn't do as you expect again, if you look at the part number on the relays G3MB 202P. You need the G3MB 202PL the P is zero crossing the PL is non zero crossing.
