Description

The 5V 8 Channel Relay Module with Optocoupler Isolation is designed to safely switch multiple high-voltage AC or DC loads using low-voltage control signals from microcontrollers and embedded systems. The module features eight independent relay channels, allowing simultaneous control of electrical devices such as lighting systems, motors, pumps, fans, solenoid valves and industrial equipment.

Built with Songle SRD-05VDC-SL-C relays, the board supports reliable switching performance while the integrated optocoupler isolation helps protect the control circuit from electrical noise and interference. The JD-VCC isolation option enables separate power supplies for the relay section and logic section, improving system stability in demanding applications.

Clearly labeled input pins, LED status indicators and screw terminal connectors make installation straightforward for beginners and professionals alike. Whether you are building a smart home automation system, industrial control panel, robotics project or IoT application, this relay module offers dependable operation and easy integration with popular development platforms. Chip.pk supplies genuine electronic components for students, engineers, makers and industries across Pakistan.
