I built and 8 outlet version of this to drive some lamps. The SainSmart relays couldn't handle fast cycling and the contacts fused. This happened when using only 60W incandescent bulbs across each relay. That's well below each relays rated current threshold. Anyone building a lamp controller like this would be advised to either slow their cycle rate or use better relays. Solid state relays may work better, especially for low current draw setups running LED lights.
Nice. This mechanical relay would drive me nuts especially at night. Solid state relay would last longer, would respond faster and don't make that annoying sounds. I'm building a similar project but will be wireless using xsource 433mhz transceiver, less wires, and i can put lights 100 feet away from the controller as long as there is power source.
Hi I am running an home automation software HA,, Can the relay handle
hooking up to a washing machine (+or-) to cut the power off? I have some
5v single relay and I like to ask 1st before I start connecting them to
receptacles. Also I notice an 14gauge with cannot fit the relay
because the screw cannot screw in. any ideas of relays I can use for my
project . I want to cut off my washing machine and well pump when its
not is use... I notice those relays are only 10amps
Arduino Uno (or homemade as seen). Sainsmart 8 relay module 5v. 2 - deep 4square boxes. 2 - double duplex raised covers. 3 - duplex recepts (break only ungrounded tab on each). 1 - switch/recept combo. 10a inline slowburn fuse 250v. Power cord. 6in. din rail. 6 terminal strips with jumpers and 2 end stops. #16 awg stranded wire. Misc wires, crimps, fork terminals, wire nuts. Let me know if you have more questions on operation, assembly, parts etc. I can be more specific if needed.
