Will A 6V Relay Work With 5V?

It is not good practice to rely on a 6 volt relay to pull in on less than 5 volts. (There will be some voltage drop between the collector and emitter of the transistor.) Les. When the key was pressed I need the arduino to switch a relay which turns on 12v leds, a simple relay.

Can we connect 9V battery to 5V relay?

Yes. Probably. You need to find out the current that the relay coil needs when it is fed at 5 volts. Then you need a resistor that will drop, lose.

Will a 6v relay work with 12v?

Description. This circuit allows a 12v relay to operate on a 6v or 9v supply. Most 12v relays need about 12v to “pull-in” but will “hold” on about 6v.

Can I run 12v relay on 5V?

You cannot activate a 12Vdc relay with 5V.

How does 6v relay work?

When you give DC supply to 2 of its terminals of electromagnet, switch is shifted from N/C position to N/O position. Now the 6V relay is operated by giving a 6V supply to the electromagnet while a 12V relay has to be operated by giving a 12V supply.

Can I use a 9V power supply on a 5V?

Of course it’s not alright to use a 9V adapter for a 5V device.

How do you convert 6v to 5V?

1. The best way to do that is to use a 7805 voltage regulator. 7805 converts any unregulated power supply above 5 Volts (say 6volts or 9 Volts) to 5 Volts .
2. Use a zener diode.
3. Use a voltage divider circuit V1=V(r2/(r1+r2) ) and V2=V(r1/(r1+r2))

How much voltage can a relay handle?

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.

What is 5V relay?

A 5v relay is an automatic switch that is commonly used in an automatic control circuit and to control a high-current using a low-current signal. The input voltage of the relay signal ranges from 0 to 5V.

Do relays have minimum voltage?

Does this happen in all relays? As you can see, the pick-up voltage, what we know as the pull-in voltage is 75% of the maximum. That means the minimum voltage required to activate this relay is 5 x 0.75 = 3.75V.

What is difference between 5V and 12V relay?

What is the difference between a 12V relay and a 5V relay? The voltage ratings are what the coil needs to energize properly. The 12V coil will likely have a higher resistance than the 5V coil. Coil resistance, voltage and current are completely independent from the relay contact ratings.

How many amps before you need a relay?

You will often see circuits carrying less than 20 amps switched directly, while circuits of 30-40 amps can sometimes be directly switched but will often be controlled by relays. Anything above 40 amps is pretty much always on a relay.

How can I make 12V relay module at home?

DIY Relay Module Making

1. Step 1: 12V Relay. Buying Link.
2. Step 2: PCB Board. I have used Dot PCB Board.
3. Step 3: Any PNP Transistor. Use any PNP Transistor Which Can Handle 20mA At least.
4. Step 4: PC817 Opto-Coupler.
5. Step 5: Resistor.
6. Step 6: PCB Mount Screw Terminal Block.
7. Step 7: Push Switch.
8. Step 8: Indicator LED.

How does a 5 pin relay work?

5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits. They have both normally open and normally closed connection pins. When the coil is activated, power will be switched from the normally closed pin to the normally open pin.

Why use a relay instead of a switch?

Relays can reduce the need for high-amperage wiring and switches, which are expensive and take up space. Therefore, switching to relays in your electronic systems can reduce the size or weight of a casing, for instance, or allow manufacturers to fit more functionality into a space of the same size.

Can I use a 12V power supply on a 6V device?

If the device has its own internal switching regulator, the voltage probably won’t be a problem, but since the 12V power supply has a lower maximum power (12V * 0.35A = 4.2W, and 6V * 1A = 6W), it may draw too much power and the power supply will be damaged.

What happens if you plug a 12V into a 5V?

The device will very likely burn out. In addition, depending on what the device is and the capacity of the 12V supply, connecting a 12V supply to a device rated 5V max could lead to a hazard – fire, explosion, etc.

Can I use a 4.5 V adapter to power a 5V device?

They’re very stable on the output voltage and can kick out an amp or so. It’ll work fine.

Can I use a 6V adapter to power a 5V device?

If you’re mildly comfortable with electronic circuits, you could convert the 6V adapter to 5V. This can be done by hooking up the output of the adapter to a simple 5V linear regulator (the 7805) — the dropout would probably be low enough at 200mA to supply 5V.

Can I use 5V for 6V?

The short answer is No. A 5V, 2A adapter gives 10W of power and the 6V,1A gives only 6W.

Can you run a 6V motor on 5V?

Yes, a 6 VDC motor of that type should run at an RPM proportional to the voltage. Torque can be the same at the lower voltage, so power will depend on the RPM, and will be about number you quote.
