KY-019 1-Channel 5V Relay Module 10A

The KY-019 1-Channel 5V Relay Module is an essential component for engineers and makers looking to bridge the gap between low-voltage digital logic and high-power AC or DC loads. Utilizing a reliable electromechanical relay, this module allows microcontrollers operating at 5V to safely switch appliances, motors, and lighting systems drawing up to 10A at 250V AC or 30V DC.

Designed for easy integration, this compact module is fully compatible with popular development platforms like Arduino, Raspberry Pi, and ESP32. It features standard input header pins for VCC, GND, and signal control, alongside robust screw terminals for secure high-voltage load connections. An onboard LED provides immediate visual feedback of the relay's switching state, streamlining the debugging process for your smart home or industrial IoT circuit diagram.

Features:

• High Switching Capacity: Safely controls heavy loads up to 10A 250VAC or 10A 30VDC.
• Logic Level Compatibility: Easily triggered by standard 5V digital signals from microcontrollers.
• Onboard Indicator: Features a status LED that illuminates when the relay is energized.
• Secure Connections: Equipped with heavy-duty screw terminals for Normally Open (NO), Normally Closed (NC), and Common (COM) wiring.
• Compact Design: Optimized PCB layout ideal for space-constrained DIY automation projects.

Package Includes:

1 x KY-019 1-Channel 5V Relay Module
