5V Relay Module (1CH)

Description

The 1 Channel Relay Module is a compact and reliable switching module designed for controlling high-voltage AC or DC appliances using low-voltage microcontrollers. It allows Arduino, Raspberry Pi, ESP32, ESP8266, and other development boards to safely control electrical devices such as lights, motors, fans, pumps, and home appliances. This module features an onboard relay, driver transistor, optocoupler isolation (in selected models), and status LED indicators for stable and safe operation. It is widely used in automation systems, IoT projects, industrial control, and smart home applications. Features Single channel 5V relay module Supports high-voltage AC and DC switching Compatible with Arduino, Raspberry Pi, ESP8266, ESP32, and AVR boards LED status indicator for relay operation Transistor driver circuit for reliable switching Screw terminals for easy wiring connection Low trigger current with stable performance Compact PCB design for easy installation Applications Home automation systems Smart appliance control Industrial automation Motor and pump control Lighting control systems IoT switching applications DIY electronics projects Technical Specifications ParameterValueOperating Voltage5V DCRelay Channels1 ChannelTrigger SignalLOW Level TriggerSwitching Capacity250V AC / 10A or 30V DC / 10AInterface TypeDigital InputIndicator LEDYesMounting TypePCB MountCommunicationTTL Control Signal Package Includes 1 × 1 Channel Relay Module
