Description
Product Description
This 2-Channel Solid State Relay (SSR) is a versatile and reliable switching module designed for safely controlling AC loads using low-voltage DC signals. It is an ideal solution for applications requiring electrical isolation between the control circuit and the load circuit, such as in home automation, industrial control systems, and IoT projects.
The module supports a wide input control voltage range (5V, 12V, or 24V DC) and features a selectable High/Low-level trigger, offering flexibility for different microcontroller platforms (like Arduino, STM32, PLC) and control logic requirements. Each channel can independently switch AC voltages up to 240V, making it suitable for controlling lights, heaters, motors, and other AC appliances.
Built with optocoupler isolation, it ensures enhanced safety by preventing high-voltage interference from damaging your low-voltage control circuitry. The compact design, screw terminal connectors, and LED channel indicators make installation and operation straightforward for both hobbyists and professionals.
