2 Channel Relay Module rated for up to 30 A per channel, designed as a robust controller for automation and industrial systems. It uses optocoupler isolation to support and low level triggering while handling loads up to 30 A at 30 V or 250 V. The module features large power relays and LED indicators for each channel, ensuring stable performance and easy status monitoring. It offers a life of 10 million operations and a maximum switching frequency of up to 5 kHz. Suitable for electrical engineers, enthusiasts, and developers, this module provides a versatile solution for circuit modifications and electronic experiments. Compact in size with mounting holes for easy integration into existing setups, it is well suited for home systems, controllers, and industrial automation. Use scenarios: Home automation: control power devices such as lighting, pumps, or HVAC components from a microcontroller or automation controller. Industrial automation: remote or centralized control of motors, heaters, or solenoids with protection for the control side via optocoupler isolation. Prototyping and education: experiment with relaybased circuits, learn isolation and switching behavior, and develop electronics projects.
