    UK Switching relay

    x I am setting up a series of fish rearing tanks. Each tank will have a 240v centrifuge to collect sediment as I’m drawing water from my lake. The centrifuge has an automatic switch off when the sediment builds up and needs emptied. In the water line is a 240v 30amp UV sterilisation light. If...

    Automotive Relays in series

    I have a specific scenario where my new spot light/flood light pods have three wires feeding them. (Black-Ground, Red-white LED, Yellow-Amber LED) as you can imagine I’d like to have a simple operation to use on or the other but only if the fog light switch is active essentially giving the go...

    How do I synchronize 2 light bulbs using relays?

    Hey everyone, here's my imaginary problem, let's say I have 2 light bulbs, both of them take energy from the same source, however, 1 of them has a button to turn it off, the other one does not. How would I make it so when that button is pressed the other light bulb also turns off? The second...

    What is the name of this circuit?

    Hello, I am looking for the name of this type of circuit and how it gets wired. If it isn't too complicated it may become a DIY project but want to be able to know what I am looking at if I hire a pro. I have two 120 volt single medium lamp socket wall sconces. I want them on either side of my...

    2 Relays for High Beam and Flasher?

    I recently installed new headlights units on my 2004 BMW Z4. The issue is the car had xenon for high/low beam then a separate bulb for flashing brights. Because of this the new high beams, separate from low beam. Only work when flashing and not for running high beams. Would it be a viable option...

    Motor Controls Challenge

    I"m a student learning motor controls and created a challenge for myself but am stuck. Here is the challenge: Challenge 1 A) Using a blower (compressed air) set to a min level so that it would keep the light bulb from turning on. No air or falls below the min level, and fail the light comes...

    Relays coils

    Bit of a random question but I’ve got a practice reason for asking. I know with a lot of control circuit timers and relays they state on them what there contacts can carry for example 2amp inductive 5amp resistive. My question is if we are pulling in a relay through these contacts is it possible...

    Why not use a latching relay to power the headlights instead of two regular relays?

    I was wondering why why not use a latching relay to power the headlights instead of two regular relays? It seems less complicated to me.

    Removing a relay

    I'm trying to learn more about relays. Can someone link to a resource that describes how they work? I mean like a wiring diagram of 1L1 3L2 5L3 2T1 4T2 6T3... Here is a LC1K09 that is connected to a lighting circuit. What are the alternative ways to remove/disconnect it and instead have the...

    What are these relays in the fuse box?

    Hello, can someone explain to me what these are and how they work? I suspect these are relays that control the electro heaters because the heating dials have an On and Night setting. Or because there is a dial in another part of the house where I assume some kind of schedule can be programmed...

    Multiple motion sensors for one lightning circuit problem

    Hey Guys! I have a little complex task. Its working overall, but i want to understand some strange acting of the motion sensors. Basically 3 lightning circuits to control with 4 motion sensors which are the same EGLO detect me 6. 1., The sensor 1 lets say M1 and the sensor 2, lets say M2...

    Smart home relays conformity?

    Hi Guys, Hope someone can advise. Going to be rewiring my house soon and going to be designing it with smart relays for all the lighting circuits. The relays will be in one central location with all lighting circuits ran to the central JB. The electrician inspecting and testing the install...

    Can anyone tell me please how to wire 3. 8PIN relays?

    Can anyone please tell me how to wire 3 8Pin relays together? Those 3 relays are for access control controlling the doors, so when the fire alarm triggered will disenergized those 3 relays and unlock the doors. Thanks

    Relays to control lighting in a domestic house.

    Hi all I'll freely admit, I'm out of my depth here. I've been asked to sort some lighting in a bathroom do do the following: Main lights and some accent lights from one switch. Mirror lights and the same set of accent lights from another. I guess it can be done using 230v relays, but haven't a...

    Impulse relays

    Hi. I have a problem with these relays. They are controlling the lightning in my house. Light are always on and switches are not working. Lights can be turned off only from main fuse. Lights have 24v transformer. Is there some kind of trasformer or fuse controlling the relays witch can be broken?

    I have 2:30 amp relays running the door poppers for my shaved door handles. They only seem to work properly when the Vehicle is running. Is this an alternator a battery relay or perhaps a wiring problem?

    Changing original 32Amp contactors for solid state relays?

    Hi Guys, My underfloor heating has 3 x 32amp contactors. They make a hell of a thump when opening and closing. Bit of a hum also. I'm looking at the idea of changing them for solid state relays like this one Solid State Relay - 40A (3-32V DC Input) - COM-13015 - SparkFun Electronics -...
