This relay can be used to switch High power (whether AC or DC) to a load by driving the relay coil with a far much lower voltage and current. When Current flows through the relay coil, It makes or breaks its contacts through electromagnetic induction. A relay contacts comprises of the Normally-Open (NO) and Normally Closed (NC) contacts. These refer to the state of the relay contacts when the relay coil is not energized. When driving a relay coil from a digital output or transistor, always connect a diode in reverse bias across the coil of the relay in other to avoid the resulting back-emf that appears across the coil of the relay when its turned off from damaging the digital device or transistor.

Relay Pin Configuration
Pin Number | Pin Name | Description |
1 | Coil End 1 | Used to trigger(On/Off) the Relay, Normally one end is connected to 12V and the other end to ground |
2 | Coil End 2 | Used to trigger(On/Off) the Relay, Normally one end is connected to 12V and the other end to ground |
3 | Common (COM) | Common is connected to one End of the Load that is to be controlled |
4 | Normally Close (NC) | The other end of the load is either connected to NO or NC. If connected to NC the load remains connected before trigger |
5 | Normally Open (NO) | The other end of the load is either connected to NO or NC. If connected to NO the load remains disconnected before trigger |
Applications of Relay
- Commonly used in switching circuits.
- For Home Automation projects to switch AC loads
- To Control (On/Off) Heavy loads at a pre-determined time/condition
- Used in safety circuits to disconnect the load from supply in event of failure
- Used in Automobiles electronics for controlling indicators glass motors etc.
