4-Channel SSR Solid State Relay - 5V Previous 
The 4-Channel Relay Module - 5V is a switching module for controlling high-voltage and high-current circuits from a low-voltage microcontroller or other control device. It operates at 5V DC and provides four independent channels for separate control. Each channel uses a Low-Level Trigger and activates when the input signal goes low. The module includes screw terminal blocks for external wiring, LED indicators for channel status, and an optocoupler for isolation between input and output. It is suitable for electronics, robotics, and automation projects that require relay-based switching.
