Description: This is a high quality single pole, double throw (SPDT) sealed relay from Omron. ... Use them to switch high voltage, and/or high current devices. The coil voltage on this relay is rated at 12VDC, and the load current is rated up to 10A.
What is the difference between SPST and SPDT relay?
SPST simply mean single pole, single throw. The product controls one circuit with one On position. SPDT means that it is a single pole double throw which means it has two ON positions . This can be a variety of circuitry however.
What is a SPDT relay?
SPDT ( Single-Pole Double-Throw ) relays have a single set of Form C, break before make or transfer contacts. That is, a common terminal connects to either of two others, never connecting to both at the same time. Including two for the coil, such a relay has a total of five terminals.
What does SPDT relay mean?
The SPDT Relay(30A) is a high quality Single Pole Double Throw Relay (SPDT). The Relay consists of a coil, 1 common terminal, 1 normally closed terminal, and one normally open terminal. When the coil of the relay is at rest (not energized), the common terminal and the normally closed terminal have continuity.
What is a SPDT relay used for?
Relay is a electro-mechanical switch used to control high power application through low power signal electronic circuits , for an example a simple timer circuit working under 5V DC bias can not control high voltage light bulb, by introducing Relay component we can easily control light bulb.
What SPDT stand for?
A Single Pole Double Throw (SPDT) switch is a switch that only has a single input and can connect to and switch between the 2 outputs. This means it has one input terminal and two output terminals. A Single Pole Double Throw switch can serve a variety of functions in a circuit.
What is DP switch?
What is a double pole switch ? Double pole switches are connected to two separate electric circuits. They essentially contain 2 switches which are linked together and can complete the circuit either simultaneously or staggered.
What are the types of relays?
- Electromagnetic Relays.
- Latching Relays.
- Electronic Relays.
- Non-Latching Relays.
- Reed Relays.
- High-Voltage Relays.
- Small Signal Relays.
- Time Delay Relays.
What is DPST relay?
DPST – Double Pole Single Throw .
Equivalent to two SPST switches or relays actuated by a single coil. Including two for the coil, such a relay has six terminals in total. The poles may be Form A or Form B (or one of each).
What happens if you put a relay in backwards?
Often seen as a quick fix, using the wrong relay for the application can cause inadvertent voltage spikes . ... Many relays, if installed for the wrong application, could and will cause a short (Internal Relay Circuit) and most likely cause functionality issues or even damage to the vehicle computer systems.
How many amps before you need a relay?
Most automotive relays are at least 30A (check the specs to make sure). This means they can transmit 30A without issue. The fuse holder you are looking at, however, cannot handle that much amperage.
Why is relay used?
Relays control one electrical circuit by opening and closing contacts in another circuit . ... Relays are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices except for small motors and Solenoids that draw low amps.
Can a relay be a SPDT type switch?
So basically you can see the SPDT relay as a way of switching between 2 circuits : when there is no voltage applied to the coil one circuit “receives” current, the other one doesn’t and when the coil gets energised the opposite is happening.
Do I need a relay?
A relay is an electrical switch that lets a low current circuit control a high current circuit such as a large LED light bar. ... If you are using a light pod that does not have a very large amp draw, you may not need a relay switch, but if you are using a larger LED light bar, they are a must have.
