Can I put 24V through a 12V relay?

Just doubtful. 24V relay never work at 12V weather is a AC or DC voltage. If you want to know the pickup voltage of relay, you just set testing setup with variable voltage source.

Is there a 24V relay?

The 24v relays feature silver contacts for durability and a removable metal mounting tab for convenient installation. All relays are rated to 500,000 cycles and now feature a braided power strap for increased reliability.

Will 5V trigger a 12V relay?

You cannot activate a 12Vdc relay with 5V.

Can I use a higher amp relay?

Yes, if it will fit in the space you have, and it has the same or better dc ratings. A relay rated for 50 amperes ac may well fail on the first operation, as the relay contacts designed for dc circuit interruption are much more robust than for the same current ac circuit contacts.

Can I use a 12V power supply on a 24V device?

No. Or almost certainly not. Any electronic device won’t work very far outside its design limits, and might be damaged – at least if the voltage is too large. A 24V device might work between 19V and 33V; a professionally-made device will have a published working voltage range.

How many volts does it take to trigger a relay?

Most are rated at 12v, usually a range of 12-15v. Actual voltage required to operate the relay is usually a little under 12v. That is why your accessories can still operate with the key on and engine off, usually making actual voltage a bit under 12v with lights on.

How to turn on 12V to 24V?

The 12V circuit that this creates will always be on, you can make it be switched (such as by the ignition switch) by simply wiring it through a 24V relay.

Can a 24V relay run on 12V?

This is because most so-called “24V” relays only need the full voltage while actually switching over. Once the relay has pulled in, most “24V” relays will hold in quite satisfactorily on 12V or even less. So there’s actually no need for a continuous 24V supply – all you really need is that first short pulse.

How does an a relay convert voltage?

A relay does not convert voltage by itself, but it’s useful for converting a signal to a different voltage (for example, a 24V brake light signal to 12V). You can think of a relay as a switch that is turned on/off using voltage instead of a finger.

How do I connect fig to a 24V DC relay?

If a low-side switch is what you need, simply connect Fig,1 to a 12-13.8V DC supply rail and most 24V DC relays will function almost as normal. However, we can simplify it a little more…
