⚡ 8-Channel Relay Module - Smart Control of Electrical Loads ⚡
The 8-Channel Relay Module allows you to control up to eight electrical devices independently using low-voltage signals from microcontrollers like Arduino or Raspberry Pi. Each relay can switch AC or DC loads, making it ideal for home automation, robotics, and industrial control projects.
✅ Technical Specifications:
- Number of Channels: 8 independent relays
- Operating Voltage: 5V DC (some modules support 3.3V to 5V)
- Coil Activation Current: ~70mA per relay
- Relay Rating: Up to 10A at 250V AC or 30V DC
- Built-in Protection: Flyback diode for each relay
- Control Signals: TTL low-level trigger
- LED Indicators: For each channel to show status
- Relay Type: Normally Open (NO) and Normally Closed (NC)
🔹 Features:
- Easy interfacing with low-voltage microcontrollers
- Capable of driving high-power devices like lamps, fans, pumps, and appliances
- Reverse voltage protection for safe operation
