Are all 12 volt relays the same?
The problem is, not all relays are the same. Just because it has the same number/location of terminals, doesn’t mean the relay works for that application. Some relays, when used for the wrong application, can generate a voltage spike over 100V on a traditional 12V system.
How many volts does it take to change a 12V relay?
The nominal voltage of a 12V relay is 12V, so 80% of this is 12 x 0.8 = 9.6V. So in theory, this relay should activate at 9.6V.
Can you use a 24 volt relay on a 12 volt system?
Reply By: Peter 2. Having tried it on my Humvee the smoke escapes very quickly and the relay will no longer work ;-))) but as has been said you can use a 24v relay to switch 12v and vice versa. The actual relay coil requires the corredt voltage. The switching contacts can handle either.
What is automotive 12V relay?
12 Volt Automotive Relays. Automotive relays are for use in 12 volt electrical systems. Relays are used when you need to switch higher currents than a switch can handle, or when you want to isolate an electrical circuit. Our relays have either 5 contacts or 4 contacts. Relays with 5 contacts are called Changeover Relays,…
What does a 12 volt relay switch do?
A relay works by using a switch to run 12 volts to the relay. The relay acts as an electrical switch that activates and draws power straight from a good fused battery connection and sends it to the lights or accessory.
What is automotive relay?
An Automotive Relay is used to pull signal from a source (Headlight connector) that triggers power to be drawn from the battery. There are two sets of cables meant to provide power to an HID ballast.
