    Description

    The 24V 30A 1-Channel Relay Module with Optocoupler Isolation is a high-power control module built for safely switching AC and DC loads in electronic and industrial automation systems. Featuring an optically isolated input, it protects low-voltage microcontrollers such as Arduino, ESP32, or STM32 from high-power circuit interference. This module supports both high-level and low-level trigger modes, allowing flexible compatibility with various logic control systems. With its robust relay rated for 240V AC or 30V DC at 30A, it can control motors, lighting, fans, pumps, and other large electrical appliances. The integrated LED indicators for power and relay activity make debugging simple and efficient. Built with safety and reliability in mind, this relay module is ideal for IoT, home automation, and industrial automation projects requiring high-current switching and stable performance. Featured By RoboticsBD.
