4 channels SSR

This 4-channel solid state relay module operates at 5 volts with stable, reliable triggering for industrial automation and control applications. Each channel provides optical isolation and zero-crossing detection, ensuring clean switching of AC loads without mechanical wear or contact bounce. Ideal for HVAC systems, lighting control, and motor management, the SSR delivers consistent performance across repeated cycles. The compact design integrates seamlessly into control panels and embedded systems requiring simultaneous multi-channel switching capabilities.
