Be sure to choose a relay that can handle your voltage and current requirements to ensure the relay coil doesn't burn out and your circuit doesn't get damaged.

Question 7 months ago on Step 6.

Hi I need. A circuit perhaps using a DPDT relay which will allow a mains powered 12v transform feed to a 12v air pump to switch to a 12v battery feed to the air pump in the event of mains power loss.

Question 8 months ago on Step 6. I want to install a remote control fog-lights to my car. The wattage of each halogen foglight is 55 watts.

My question is, can I use the wireless controller shown below with a relay to power 2 fog-lights under 12 volts power source. I hope someone is still looking at this Instructable Good article as it helped me understand relays a lot better than I did before. I am confused about relays wrt AC vs DC loads.

Is it possible to use a generic solid-state relay to drive a DC load? A related question has to do with the power supplied to each side of the relay. But is it possible to find a power supply that provides multiple outputs - 3. That would simplify life quite a bit.

Reply 10 months ago. Given that the rudimentary tests allow you to use the motor at 5V You could probably power the relay and the motor via the same 5V supply.

Question 1 year ago. I've installed tracker and relay in electric moped in order to block it while it is parked. It kind of works and not. It turns off when you turn the key to ignition off course with batteries inside the bike , but for half a minute or even more it is just switching on and off constantly, so if you hit the start button when relay is on, bike starts, which is not good. I'd like bike to stay blocked immediately when key is turned to ignite and bike shouldn't be able to turn on at all.

I don't know which type of relay I am using but will check later and put it down. Any Idea how to sort this out? Thanks in advance. Question 1 year ago on Step 5. Are these two relays compatible and do the same job? They go to a main PCB on a Samsung fridge which Powers an inverter board for approximately a second or two and then shuts off not allowing the compressor to attempt or even start running.

Which relays on this board typically go bad or should be replaced in order for the board to work properly again? Answer 1 year ago. I'm having a hard time trying to find a compatible replacement relay.

It relays to a. Attached is an image. Any direction as to where I can find a compatible more recently manufactured relay would be greatly appreciated! Question 2 years ago. I'm not really savvy when it comes to this electrical stuff. Can you please tell me what brand is good and what type I need? I don't know what DP. Please help me. Question 3 years ago. Hello Sir, I am an Amateur Radio Operator and would like to use 2 10 Amp 12vdc relays to control Horizontal or Vertical transmission of my Cubical Quad antenna Transmitting element,the 10 Amp Relays are well suited for this application,my only Question is,"with the coil energised how long can it stay energised before overheating or would it even overheat"If there is a way to cool the relay coil I could do that if need be.

Thank You Bob. Answer 2 years ago. The spec sheet for a suitable Relay lists coil draw at 30mA 12V , that's so little I doubt it would ever heat up let alone over heat.
