12V Relays

Switch high-power loads with our 12V relay modules designed for automotive, industrial control, and battery-powered projects. These relay modules provide reliable switching for motors, solenoids, lighting systems, and other 12V DC applications with optocoupler isolation for enhanced safety.

Our 12V relay range includes versatile options from single channel modules for basic switching to multi-channel configurations including 2 channel, 4 channel, 8 channel, and 16 channel relay boards for complex automation systems. Each relay handles up to 10A at AC 250V or DC 30V.

Ideal for automotive electronics, solar power systems, battery management, PLC control, and off-grid applications. Compatible with Arduino, ESP32, PLC controllers, and other microcontrollers with appropriate level shifting.
