Relays are an essential component of any electrical system that involves the use of switches. They allow for remote control of switches, which makes them highly efficient and convenient. The 28146RE relay is a commonly used relay in various electrical systems. In this article, we’ll cover everything you need to know about the 28146RE relay wiring diagram.
What Is a 28146RE Relay?
The 28146RE relay is a type of electromechanical relay that is used to control high-powered electrical systems. It is a DPDT (double-pole, double-throw) relay, which means that it has two sets of contacts that are each capable of switching between two different circuits. This makes it highly versatile and useful in a wide range of electrical applications.
How Does a 28146RE Relay Work?
The 28146RE relay works by using a small amount of electrical power to control a larger amount of power. When the relay receives a signal from a switch or other control device, it activates an electromagnet that pulls the contacts together or pushes them apart, depending on the configuration of the relay. This allows the larger circuit to be turned on or off, depending on the desired outcome.
When the relay is not activated, the contacts are in their default position, which may be open or closed, depending on the configuration of the relay. This means that the power to the larger circuit is either flowing or not flowing, depending on the state of the contacts.
What Are the Applications of a 28146RE Relay?
The 28146RE relay is commonly used in a wide range of electrical applications, including:
- Automotive systems
- Industrial machinery
- HVAC systems
- Power generation and transmission
- And many more
Its versatility and flexibility make it an ideal choice for any application that involves the control of high-powered electrical circuits.
28146RE Relay Wiring Diagram – How to Wire It
Wiring the 28146RE relay is a relatively simple process that involves connecting the appropriate wires to the appropriate terminals on the relay. The wiring diagram for the 28146RE relay is shown below:
| Terminal Number | Description |
|---|---|
| 1 | Coil Negative |
| 2 | Coil Positive |
| 3 | Normally Closed Contact |
| 4 | Common Contact |
| 5 | Normally Open Contact |
| 6 | Normally Closed Contact |
| 7 | Common Contact |
| 8 | Normally Open Contact |
To wire the 28146RE relay, follow these steps:
- Connect the negative side of the control circuit to terminal 1.
- Connect the positive side of the control circuit to terminal 2.
- Connect the normally closed contact of the first set of contacts to the load that will be turned on or off by the relay.
- Connect the common contact of the first set of contacts to the power source for the load.
- Connect the normally open contact of the first set of contacts to the load that will be turned on or off by the relay.
- Repeat steps 3-5 for the second set of contacts.
Once the wiring is complete, the relay is ready to be activated and control the load as desired.
28146RE Relay Wiring Diagram – FAQ
What is a DPDT relay?
A DPDT relay is a type of relay that has two sets of contacts that are each capable of switching between two different circuits. This makes it highly versatile and useful in a wide range of electrical applications.
What is the difference between a normally open and normally closed contact?
A normally open contact is one that is open (not connected) when the relay is not activated, and closed (connected) when the relay is activated. A normally closed contact is one that is closed (connected) when the relay is not activated, and open (not connected) when the relay is activated.
