8 Channel Relay - 5V DC with OptoCoupler Module Board (220v AC 7A)

8 Channel 5V DC Relay Module with Optocoupler for Microcontrollers & High Power Switching

The 8 Channel 5V DC Relay Module with Optocoupler is your essential solution for safely interfacing low-voltage digital logic with high-voltage AC/DC devices. This versatile board features eight independent relays, each operating on a 5V DC input. Crucially, every channel incorporates an optocoupler, providing robust electrical isolation. This protects your sensitive microcontrollers like Arduino, ESP32, and Raspberry Pi from high-voltage spikes. It's engineered to safely switch a wide range of loads, supporting up to 250V AC at 10A or 30V DC at 10A. Ideal for diverse applications from home automation to industrial control, this module ensures reliable and secure operation. Integrated LED indicators offer instant visual feedback on relay status. Convenient screw terminal blocks simplify wiring, empowering your automation projects with precise and safe high-power switching capabilities.
