4 Channel Relay - 12V DC with OptoCoupler Module board

The 4-Channel Relay Module (12V DC) is designed for controlling high-voltage devices using low-power microcontrollers, PLCs, or other control systems. It features optocoupler isolation, ensuring safe signal transmission and protection from voltage spikes or interference. This module can be used to control AC or DC loads, making it ideal for home automation, industrial applications, and electronic switching projects.

Each of the four relays on this module is rated for high-current switching, enabling reliable operation of motors, lamps, pumps, solenoids, and other electrical appliances. The built-in LED indicators provide a clear status of relay operation, while the screw terminal connectors allow for secure wiring. The module’s compact design and durable build make it suitable for both DIY projects and professional applications.
