The Importance of Double Pole Double Throw Relays
As an electrical engineer, I have worked with various types of relays in my career. However, the one that I always find myself using and recommending is the Double Pole Double Throw (DPDT) relay. This type of relay has proven to be essential in a wide range of applications and here are some reasons why.
First and foremost, DPDT relays offer a high level of versatility. They have two sets of contacts that can be used to control two independent circuits. This means that they can be used for both switching and reversing applications. For example, in motor control, DPDT relays can be used to change the direction of rotation by simply switching between the two sets of contacts.
Another reason why DPDT relays are necessary is their ability to handle higher voltages and currents compared to other types of relays. This is due to the fact that they have two sets of contacts in parallel, which allows for greater current carrying capacity. This makes them ideal for use in high-power circuits where safety is a top priority.
Moreover, DPDT relays offer reliable switching capabilities. They have separate poles for normally open (NO) and normally closed (NC) contacts, which ensures that there
My Buying Guide on ‘Double Pole Double Throw Relay’
As an electronics enthusiast, I have had my fair share of experience with different types of relays. However, when it comes to switching between two circuits simultaneously, the double pole double throw (DPDT) relay is my go-to choice. In this buying guide, I will be sharing my knowledge and experience on what to look for when purchasing a DPDT relay.
What is a Double Pole Double Throw Relay?
Before delving into the buying guide, let’s first understand what a DPDT relay is. A DPDT relay is an electromechanical switch that has two inputs and four outputs. It allows you to switch between two circuits by energizing one coil, which in turn energizes one set of contacts while de-energizing the other set.
Consider the Coil Voltage and Current Rating
When purchasing a DPDT relay, the first thing to consider is the coil voltage and current rating. The coil voltage should match the voltage of your control circuit, while the current rating should be able to handle the maximum current of your circuit. It is essential to check these specifications as using an incorrect voltage or current rating can damage your relay.
Choose Between Latching and Non-Latching Relay
There are two types of DPDT relays: latching and non-latching. A latching relay will stay in its energized state even after power is removed from its coil until it receives another pulse to change its state. On the other hand, a non-latching relay requires continuous power supply to stay in its energized state.
If you need a DPDT relay for a specific purpose that requires it to stay in its energized state for an extended period, then a latching relay would be suitable. However, if you need it for a more standard application, a non-latching relay should suffice.
Consider the Contact Rating
Another crucial factor to consider is the contact rating of the relay. The contact rating determines the maximum voltage and current that can be handled by the relay’s contacts without causing any damage. Make sure to select a DPDT relay with a contact rating that is higher than your circuit’s requirements to prevent any potential damage.
Choose Between PCB or Socket Mounting
DPDT relays come in two types of mounting options: PCB (printed circuit board) and socket mounting. For PCB mounting, you need to solder the relay onto a circuit board, while for socket mounting, you can easily plug in and remove the relay from its socket.
If you are looking for portability and easy replacement, then go for socket-mounted relays. PCB-mounted relays are suitable for permanent installations.
Check for Additional Features
Some DPDT relays come with extra features such as LED indicators, diode protection, and built-in resistors. These features can add convenience and protection to your circuit. Consider if these features are necessary for your application before making a purchase decision.
Final Thoughts
In conclusion, when purchasing a DPDT relay, make sure to consider its coil voltage and current rating, choose between latching or non-latching type, check the contact rating, decide on the mounting option, and look out for additional features. By keeping these factors in mind, you can ensure that you select the right DPDT relay for your specific needs. Happy shopping!
