Two-channel relay module equipped with optoisolated control inputs and relays with 5V coils. Designed for controlling loads up to 10A at 250VAC from a microcontroller or development platforms
The relay module is designed for controlling actuators using digital signals generated by microcontrollers and development platforms. The solution enables safe switching of loads powered by AC mains or DC voltage, such as lighting, motors, solenoid valves, and other electrical devices that require isolation from the logic control section.
The board is equipped with two electromagnetic relays with 5V coils, whose contacts allow switching currents up to 10A at 250VAC or 110VDC. Optoisolated control inputs separate the logic signals from the relay circuits, reducing interference and increasing the operational safety of the microcontroller.
Connection outputs

The module supports control signals with logic levels of 3.3V and 5V. The relays are activated by a low logic level. A jumper between the VCC and JD-VCC lines allows independent power supply of the logic section and the relay coils. Standard 2.54mm pitch pin headers and ARK screw terminals facilitate integration with installations and mounting in prototyping and educational projects.
