2-Channel Relay Module

The 2-Channel Relay Module (12V DC) is a versatile switching solution designed to interface low-voltage control systems with high-voltage electrical loads. Whether you’re working with microcontrollers like Arduino, PLCs, or other digital control logic, this module provides a safe and efficient way to operate motors, lamps, solenoids, and other devices requiring higher current or voltage.

Operating on a 12V DC input, the module is fully compatible with most control platforms and features two independent relay channels, each capable of handling up to 10A at 250V AC or 10A at 30V/28V DC. This makes it ideal for switching both AC-powered appliances and DC-driven devices in a wide range of automation projects.

Each relay is connected to clearly labeled green screw terminal blocks, allowing for easy, secure wiring of both the control inputs and the switched outputs. LEDs indicate the relay status in real-time, aiding in diagnostics and testing during setup or maintenance.

The compact, board-level design is well-suited for industrial control cabinets, home automation systems, robotic control, and custom electronics projects. You can use it to independently control two devices from a single controller or build a more complex multi-relay system for broader applications.

With durable construction and support for isolated control, this 2-channel relay module ensures reliable switching performance, electrical isolation, and long operational life—even in demanding automation environments.
