The Ultimate Guide to 4-Pin Relay Wiring Diagrams

4-Pin Relay Wiring Diagram

A 4-pin relay is a type of electrical switch that is used to control the flow of electricity in a circuit. It has four terminals, which are typically labeled as follows:

• Terminal 1: Coil terminal 1
• Terminal 2: Coil terminal 2
• Terminal 3: Normally open (NO) contact
• Terminal 4: Normally closed (NC) contact

When the coil of the relay is energized, the contacts will change state. The NO contact will close, and the NC contact will open. This allows current to flow through the circuit. When the coil is de-energized, the contacts will return to their original state. The NO contact will open, and the NC contact will close.

4-pin relays are commonly used in a variety of applications, such as:

• Controlling the flow of electricity in a circuit
• Isolating circuits from each other
• Protecting circuits from overloads

When creating a 4-pin relay wiring diagram, it is important to follow these steps:

1. Identify the purpose of the relay.
2. Determine the coil voltage and current requirements.
3. Select a relay that has the appropriate contact ratings.
4. Draw the circuit diagram.
