A Double Pole Double Throw (DPDT) relay is a switch that has 8 terminals. It works by the application of an electric current to the coil which in turn activates the relay. This allows the switch to be either switched on or off. This switch is commonly used in a variety of applications, such as motor control, lighting control, and door chimes. Understanding how to read an 8 pin DPDT relay wiring diagram is important in order to successfully wire the switch.
Reading the Wiring Diagram
The wiring diagram for an 8 pin DPDT relay is relatively straightforward. It consists of 8 pins that are labeled with numbers or letters. The numbers or letters correspond to the terminal numbers on the switch. The diagram also includes pictorial representations of the connections that need to be made. The diagrams are usually found on the inside of the relay’s cover, or on the back of the switch.
Making Connections
Once the wiring diagram has been understood, the next step is to make the appropriate connections. This is done by connecting the wire from the power source to the appropriate pin on the switch. The wire must then be connected to the terminals on the switch. Once all the connections have been made, the switch can then be tested to ensure that it is functioning properly. If any problems are encountered, the wiring diagram should be consulted to ensure that the correct connections have been made.
Conclusion
Understanding how to read an 8 pin DPDT relay wiring diagram is an important part of wiring and controlling electrical systems. Knowing how to correctly connect the wires and terminals is essential in order to ensure that the switch functions correctly. With a little patience and knowledge, one can easily understand and properly wire an 8 pin DPDT relay.
