iRhapsody Relay 12V 5-Pin SPDT Automotive Relay Kit — 40A/30A High-Current

Meet the iRhapsody Relay Kit, a 25‑piece collection of 12V DC relays designed to help you manage power across automotive and other 12V systems. Each unit uses a compact 5‑pin SPDT configuration, enabling clean, reliable switching for loads like lighting, audio, security components, and more. The kit is built to perform in real‑world conditions, from city streets to outdoor installations, without demanding new wiring hierarchies or special tools.

With a focus on fast, decisive switching, these relays are suited to applications where quick engagement and disengagement matter. The nominal coil voltage is 12 V DC, with a coil power of 1.8 W and a coil resistance around 80 Ω, ensuring a compact footprint while delivering dependable control signals. The relay supports a wide operating voltage range, including 6–8 V for activation and 0.6–3.6 V for release, and it can handle up to 15.6 V DC on the load side. This makes it a flexible choice for a range of 12V systems and devices.

Versatility for real-world setups

The iRhapsody SPDT relays are designed for use in vehicles and other 12V powered systems. They support car audio, lighting rigs, LED strips, security components, headlights, and various other accessories. The 5‑pin configuration (SPDT) helps you route signals between common and normally open or normally closed contacts, giving you flexible control without complicated wiring schemes.

Designed for durability and dependable operation across a range of environments, the relays withstand typical road and outdoor conditions. The combination of rapid actuation, robust electrical life, and a broad temperature span makes them suitable for both daily commuting setups and more ambitious builds. While results can vary by individual installation, you may notice smoother control of auxiliary systems and improved reliability in switching tasks when using a dedicated 12V relay like this kit.
