I have a plasma cutter without a pilot arc and would now like to convert it to a pilot arc. For this, I got a hose package with pilot ignition. It contains an additional cable—I'll call it the pilot cable. For the pilot ignition, I would now like to use a switch/relay to short-circuit the…
I would like the lamp to light up after 2 seconds (time delay) by closing the normally open contacts (NO) -KM and -KT. But even though I've set everything up and wired it correctly, it still doesn't work. Do you have any idea how to make -KM and -KT close after a certain time?
Hey guys. I have a question. I'd like to control a gate opener with the Shelly. The relay that drives the gate motor is powered by a 12V AC relay. Can I simply wire the Shelly as shown in the diagram?
Hello everyone, I want to replace the defective blower relay in my vehicle. The new relay I want to purchase has the same voltage and current rating (12 volts and 40 amps) as the old one. Before I install it, I have the following questions: Is it enough that the volt and ampere values are…
Hello, I installed LED indicators on my Husqvarna WR 250. It obviously didn't work with the original relay. So I installed a load-independent one, but when I activate the left indicator, for example, the left indicators only light up (ie, they don't flash). The same thing happens on the right. I thought it was the…
Hello, I would like to install a starry sky projector in my car, which I control via a button that leads to a relay, which then controls the projector. What kind of relay do I need? The button should open the relay with one click and close it with another (on / off). I saw…
I know theoretically how a relay works and I know about a magnetic coil, armature, working current, control current, working current contact, etc. But ultimately I don't understand how a relay works in a car. Especially after the statement: The advantage of a relay is that you can switch large currents with it??? How large…
Hello, I want to operate a relay on an ESP, but I don't know how to connect it correctly. I've searched online but haven't found anything that would help me. My relay is the SRD-05VDC-SL-C from Songle. (Datasheet: https://elteile.de/media/pdf/7f/be/05/SRD_Series.pdf ) I have the model without a PCB, so I can't rely on its labels. Thanks…
Hello, Who can help me understand the circuit diagram of this latching relay? https://www.grt-relay.com/latching-relay/3-phase-three-phase-latching-relays.html What is the German term for latching relays? Self-holding relays? Impulse relays? I know about standard relays like SPDT and DPDT relays and have used them before, but latching relays are somewhat different from traditional relays. As an example experiment, I…
Good Morning, I built a circuit for a sound box that I can use with mains power and batteries! Now I've installed a relay that switches to mains power when the power cable is plugged in. Otherwise, the box runs on battery power. Now the problem is that when I pull the power cable out…
