Details

The 4-Channel 5V Relay Module is an essential interface board for switching high-power electrical devices using low-voltage signals from microcontrollers. This module features four independent relay channels, each capable of handling up to 10A at 250V AC or 30V DC, making it ideal for home automation, industrial control, and robotics projects. Equipped with optical isolation, it protects your sensitive microcontroller circuits from high-voltage interference and spikes. The module operates at a low trigger current of 5-20mA, allowing direct control from Arduino, ESP32, Raspberry Pi, or other development boards. Each relay has a standard 3-pin interface (Normally Open, Common, Normally Closed) for easy connection to your load. The compact design includes mounting holes for secure installation. Choose this relay module for reliable switching performance, safety isolation, and broad compatibility with popular development platforms.
