    Default Control 12V relay switch

    Is it any modules that can control 12v relay switches via the profilux 4?

    I have been reading the 1-10V only can support 20ma, and thats not a good thing, but using the 1-10V to trigger a relay could work. Any electronic relays that work with the 1-10V port? (or relay modules that is dedicated for this use).

    (to control things like solenoid valves etc without using a transformator or a 220v solenoid).

    Caution: outputs per charge only 20mA, do not forget free wheeling diodes!

    You can also use S port

    Is the S port also limited to 20mA or is it the same?

    Yes,

    Use good relay like Finder 43.41.7.012.2000 (relay used by GHL in their PowerBar) and again do not forget free wheeling diodes!

    Great. Have anyone tried to use the LED Controller V2, then using a PWM relay like this http://www.ebay.com/itm/322256050081 to control 4 12v outputs?

    Can you suggest a free wheeling diode that would work with the 20ma limit of the GHL?

    Hello
    You need a relay circuit like this. Unfortunately only in German
