Description

The ELEGOO Relay Module 4 Channel DC 5V with Optocoupler is a professional-grade control solution for Arduino projects and microcontroller applications. This module operates at 5V and features four independent relays, each capable of handling maximum contact ratings of AC250V 10A and DC30V 10A, making it ideal for controlling high-current appliances and industrial devices. The optocoupler isolation ensures safe signal transmission between your control circuit and load. Built-in working status indicator lights provide visual feedback for safety and ease of troubleshooting. With a standard interface designed for direct microcontroller connections, this relay module integrates seamlessly with Arduino, Raspberry Pi, and ST platforms. Ensure your power supply delivers current exceeding 1A for reliable relay operation. Perfect for automation projects, smart home applications, and any scenario requiring robust switching of AC or DC loads.

Key Features

ELEGOO 4 Channel Relay Module operates at 5V with optocoupler isolation for safe microcontroller integration and reliable signal transmission.
