16 Channel 12V Relay Module with Light Coupling and LM2576 Power Supply
The 16 Channel 5V Relay Module with Optocoupler is a versatile and reliable switching solution designed for controlling multiple high-voltage or high-current loads using low-voltage control signals. Featuring 16 independent relays, this module allows simultaneous control of multiple devices such as lights, motors, pumps, solenoids, and appliances from microcontrollers or PLC systems.
Each relay channel is equipped with an optocoupler for electrical isolation, enhancing safety by protecting control circuits from voltage spikes and electrical noise on the load side. Operating at 5V logic, the module is fully compatible with popular development platforms like Arduino, Raspberry Pi (with level shifting), ESP32, ESP8266, and other microcontrollers.
Designed for stability and durability, the module includes status LEDs for each relay, screw terminals for easy wiring, and high-quality relays capable of switching AC or DC loads. This makes it an ideal choice for home automation, industrial control, IoT projects, robotics, and automation panels where reliable multi-channel switching is required.
