FAQ
What is the difference between normally open and normally closed contacts?
Normally open (NO) contacts remain open until voltage is applied, at which point they close to complete the circuit. This is ideal for ignition control where the relay should only conduct when commanded.
Can this relay be used in marine applications?
While the relay is designed for automotive use, its painted exterior and corrosion‑resistant contacts make it suitable for many marine environments, provided it is protected from direct water exposure.
Is the relay compatible with 12 V and 24 V systems?
Yes, the relay is rated for typical automotive voltage ranges, operating reliably on both 12 V and 24 V DC systems.
How do I replace the relay safely?
Disconnect the vehicle battery, locate the existing relay, and use the plug‑in design to pull it out. Align the new relay’s pins and push firmly until it seats securely.
What warranty does Standard Motor Products offer?
The relay comes with a limited one‑year warranty covering defects in materials and workmanship, reflecting the manufacturer’s confidence in product quality.
