Super cool! Seems that this model is 8ch. 2 relays are for on and off to power up relays. Total 10ch. I think I need to buy programming software(and cable) if I need to use all 10 relays as I want. But 8 momentary is enough right now. Someone mentioned about wiring need. Wire 2 is +12vdc. Wire 1 is -12vdc. Wire 4 is ground and rest are NO relays. It think wire 3 is for feeding 10A via relays but I have not test that. Thanks again! Buttons 3 and 4 not working as seller told!
Express delivery 14 days , kind of bulky, but seems pretty good quality. I will be using it for tow truck/wrecker. NO ENGLISH USER MANUAL !!!!!!!!
verry good product working nicely, only butons 3 and 4 are not working, green, 1 and 2 are like the others
