Description
This 4-Channel Relay Module allows microcontrollers to safely control up to four high-power AC or DC devices at the same time. Featuring optical isolation and high-current relay switches, it is an essential component for complex home automation and multi-device control projects.
Key Features:
- 4-Channel Independent Control: Switch and automate four separate appliances or electrical circuits independently from a single expansion board.
- High Load Capacity: Safely switches high-power loads up to 240V AC / 10A and 30V DC / 10A on every individual channel.
- Optocoupler Optical Isolation: Built-in optocouplers shield delicate microcontroller circuitry from high-voltage spikes, noise, and electromagnetic interference.
- Flexible 2-State Terminals: Heavy-duty 3-pin screw terminal blocks for each channel feature Normally Open (NO), Common (COM), and Normally Closed (NC) connections.
- Individual Channel LEDs: Onboard trigger LEDs give real-time visual feedback whenever a specific relay channel is activated.
- Microcontroller Compatible: Hooks up effortlessly to standard 5V logic signals from Arduino, Raspberry Pi, ESP32, ESP8266, and PIC microcontrollers.
- Versatile Applications: Perfect for multi-room smart home lighting, home automation hubs, motor sequence controls, and custom DIY electronic systems.
