Step-by-step Wiring Guide
Relay wiring can seem intimidating, but our easy guide breaks it down. We’ll go through the process step by step. Soon, you’ll have your 8-pin relay ready to go. Follow these directions closely, and remember, safety is key. Make sure the power is off before you start.
Connecting The Coils
Find the coil pins. These are usually labeled on the relay itself. Pins generally marked “A” and “B” or numbers like “2” and “7”. These pins energize the coil.
- Use your wiring diagram.
- Strip the wire ends. About 1/2 inch should do.
- Crimp or solder. Attach the wires securely to the pins.
- Secure the connections. Ensure they are tight and covered.
- Double-check the polarity. This ensures that the coil energizes correctly.
Wiring The Contacts
The next step is wiring the contacts. These are the pins that control the switch. They let your device know when to turn on and off.
- Identify Normally Open (NO) and Normally Closed (NC) pins.
- Next, find the common (COM) contacts.
- Make sure wires are prepared. Strip and crimp as before.
- Carefully connect NO, NC, and COM wires.
- Inspect to ensure no cross-wiring has taken place.
Common wiring configurations might be:
