The 4-channel Relay Board is designed to effectively control various devices such as lights, fans, and other appliances, while ensuring complete isolation from your microcontroller.

The relay’s coil voltage is 12V, making it compatible for direct use with any 12V regulator. However, for optimal performance, it is recommended to use separate regulators between your Arduino and the Relay board.

This versatile Relay Board enables you to easily manage high-power devices with a capacity of up to 10A through its on-board relays. The relay control is made accessible via a 1×3 header, which is user-friendly and can be conveniently connected to many development boards using servo cables.

Features:

Control high-power devices up to 10 A with a simple high/low signal Provides isolation between the microcontroller and device being controlled Screw terminals for relay connections 3-pin servo-style header for power/signal interface LED indicator provides visual feedback
