🔌 Wiring & Usage

1. Control Connections (12V Logic)

VCC: Connect to 12V power supply (for relay coil).
GND: Common ground (shared with control signal).
IN1, IN2: Signal pins (activate with 12V HIGH or LOW, depending on jumper setting).

2. Load Connections (Screw Terminals)

NO (Normally Open): Circuit closes when relay is ON.
COM (Common): Central contact.
NC (Normally Closed): Circuit opens when relay is ON.

⚠ Warning:

Do not exceed 250V AC / 10A per channel.
Keep high-voltage wiring separate from control circuits.

🛠 Applications

Automotive systems (12V car electronics, lights, fans).
Industrial machine control (PLC interfacing).
Home automation (appliance control via 12V triggers).
DIY power distribution panels.
Safety cutoffs & emergency switches.

📦 Package Includes

1× 2-Channel 12V Relay Module.
(Optional) Jumper caps & mounting screws.

⚡ Why Choose This Relay Module?
