    It's an "optocoupler" relay module operating at 12 Volt. Does this mean that 12 V is galvanic isolated from the arduino, that should control the relays? My first impression was: I am missing a separate ground for the relay control and for the arduino! However, after some study I discovered that you CAN operate the board with galvanic isolated 12 V and the arduino's 5 V. How? Don't use the straps!! So don't connect the 4 middle pins with straps to Ground or to VCC of the relay module, but connect these 4 pins to the arduino's ground! Now the 12V and the arduino's 5V are galvanic isolated! See photo!

    Bardzo praktyczny system przekaźnikowy, można skonfigurować różne urządzenia bez potrzeby tak wielu obwodów

    Te moduły przekaźnikowe są świetne dla Arduino łatwe w użyciu

    Had a problem where using the car lights (tail,brake,indicators etc) were creating interference on the two camera's on my caravan. This shouldn't have happened but I didn't have the time to chase Ford on why. Fitting a commercially available "lights" module into the car may have fixed this but the power to supply it is fed from the car battery and I wanted to isolate the caravan lights from the car lights. I could have bought and fitted the commercial "lights" module into the caravan but they are stupid money for what they are and, because this relay module was to be fitted in the caravan, I wasn't short of space. I fitted it so each relay was in series with each light circuit. The caravans battery supplied power to the relay module. which powered all the caravans lights. Works a treat. No more interference and at a very reasonable cost. Have a few other projects for this handy little module. Quality/delivery and price were excellent. This one is a spare. I actually used a 6-way version of this as it arrived a few days earlier.

    Items arrived. Order a mixture of electronics components, and heavy gear motors - packaging insufficient to protect electronics from heavy motors....
